Frequently Asked Questions About Dell Laptop Battery

How long does a Dell laptop battery last? When should I consider replacing mine?

All rechargeable batteries wear out with time and usage. As time and cumulative use increase, the performance will degrade. For the typical user, noticeable reduction in run time generally will be observed after 18 to 24 months. For a power user, reduction in run time generally may be experienced prior to 18 months. We recommend buying a new Dell laptop battery when the run time does not meet your needs.

How long am I able to use my Dell laptop on a fully charged battery?

Many factors affect the amount of time that a portable computer battery can deliver power before it must be recharged. These factors include the configuration (processor, memory, etc.), types of applications being run and display brightness.
Dell uses industry standard benchmarks for battery run time claims. For more information on battery run times and benchmarks, the white paper, “Understanding Battery Life in Portable Computers” is available.

How do I charge my Dell laptop battery?

The battery charges in the laptop when the laptop is connected to an AC power source via the AC adapter.

How long does it take for a Dell laptop battery to fully recharge?

The charge time varies depending on the system. If the system supports ExpressCharge, the battery typically will have greater than 80% charge after about an hour of charging, and fully charge in about 2 hours with the system off.

Should I totally discharge, then recharge my Dell laptop battery occasionally to make it last longer?

No, discharging and charging does not increase the life of a Lithium Ion technology battery.

Can a Dell laptop battery be “overcharged”?

No, the battery is designed to stop using the charger when it reaches full charge.

Does Dell sell external battery chargers?

Dell offers a Datamation battery charger for large institution customers. The charger has 16 charge bays to charge batteries for Latitude D500/D505/D510/D520/D600/D610 laptop systems. The product can be found at www.exceldigital.org.uk.

Is it easy to install a battery?

Yes, very easy. First, make sure all open files are saved. Next, either attach the AC adapter directly to the laptop or set the system to “hibernate” mode or shut off. Release the latch on the current battery, and simply install the replacement battery.

Will Dell laptops accept non-Dell batteries?

Dell has a rigorous qualification process by which all Dell batteries are validated to ensure proper function, performance and safety. Some non-Dell batteries are available in the market with claims of compatibility with Dell systems. Dell cannot verify these claims, nor the safety of using them in a Dell system. Dell strongly encourages our customers to use only Dell laptop batteries advertised as appropriate for their laptop model. Only Dell laptop batteries come with a 1-year warranty, are engineered for optimal safety and performance for Dell systems, and are supported by Dell technical support for the length of the warranty period.

What is a modular bay battery?

In some laptop systems Dell offers a battery that can be used in the optical drive media bay (DVD/CD drive bay). This enables the use of two batteries, potentially extending the available run time.

If I install a modular bay battery, are my primary and modular bay batteries working at the same time to power my laptop computer? No, the modular bay battery is used first, then the system automatically switches to the primary battery. This is a deliberate design to allow the most amount of run time to remain in the primary battery in case the modular bay battery is removed and replaced with an optical drive.
What does Dell recommend for battery storage for a long period of time? When storing for more than 4 days these guidelines can better preserve the life of your battery: Do not store batteries for long periods plugged into or attached to any power source. This includes AC adapters and laptop security carts plugged into an outlet.
Laptop batteries, including those stored in laptop systems, should maintain an Operational Storage Temperature of 0° to 35°C (32° to 95°F).
Batteries may be stored in the laptop or outside of the laptop.
Charge batteries before storing. The recommended charging time should not exceed 1 hour. Typically, this should charge the battery to between 80% and 100%. (Some discharge will take place over time. Stored batteries are expected to discharge 10-15% over a four month period, for your information.)

Cloud Computing Education Taken to the Next Level

Cloud Computing Education Taken to the Next Level

There is no surprise that cloud computing education is a necessary tool for many companies and even schools. With this type of computation system that should not be confused with others such as grid computing, utility computing or autonomic computing. Even if you are not completely familiar with cloud computing, you most definitely use it on a regular basis such in computer applications like Skype. The interesting part about cloud computing is that entire systems can be set up on a renting basis. The infrastructure of your project and the access tools and applications used can be rented rather than the more commonly owned tools to get these businesses and projects running.

The Economics of Cloud Computing

With a down spiraling economy, with already cut IT budgets, cloud computing education may be the answer to many problems, especially IT financial problems. Many critics wonder if this type of computation system will really work in the long run, if it is a quick fix for a poor economy or if it will just fizzle out like other computation promises. Regardless of the suspected hype that this new system has generated, it is true that cloud computation is another form of what most people are accustomed to such as social networking sites like Facebook and MySpace, email systems like Hotmail, email filtering companies and even security monitoring. These are all forms of clouds computation.

What Benefits Does Cloud Computing Have on Education?

It is no wonder why students find themselves in a bond. Not only do they have to worry about student loans and purchasing books, but they also have to spend hundreds of dollars on computer software in order to complete their assignments and prevent their computer from failing on them. With this in mind, cloud computing education allows computer users to use desired applications without the necessity of purchasing the software, the frustration of installing it or the hassle of taking up computer memory with support software. Through different cloud platforms like Software as a Service, Infrastructure as a Service and Platform as a Service, cloud computing is made possible.

Considering the money saved through these cloud applications, most speculate that the largest benefit that cloud computing has on education is its economic factor. Instead of purchasing software and infrastructures, renting prices are determined by how often and how many services are being used. All software and data are stored in a remote host which enables computers to free up space while also being accessible at any time for users. Considering the amount of resources that cloud computing offers, users can find just about any type of infrastructure, service or software that they need. This helps to cut costs for educational institutions or any type of organization or business that uses cloud computing since these organizations will no longer have to purchase expensive software for an individual or a limited small number of employees and students.

Many experts in the IT field believe in Cloud Computing education and the benefits that it can provide for millions of computer users on a daily basis. However, only time will tell if this computation system will prove to be a success in the world of computation.

Difference Between Impact Printers And Nonimpact Printers

What are printers? A printer is an output device that prints characters, symbols, and perhaps graphics on paper. The printed output is generally referred to as hardcopy because it is in relatively permanent form. Softcopy refers to temporary images such as those displayed on a monitor. Printers are categorized according to whether or not the image produced is formed by physical contact of the print mechanism with the paper. Impact printers have contact; nonimpact printers do not.

Impact printers

An impact printer has mechanisms resembling those of a typewriter. It forms characters or images by striking a mechanism such as a print hammer or wheel against an inked ribbon, leaving an image on paper. Impact printers are dying out; however, you may still come in contact with a dot-matrix printer. A dot-matrix printer contains a print head of small pins that strike an inked ribbon, forming characters or images. Print heads are available with 9, 18, or 24 pins; the 24-pin head offers the best print quality. Dot-matrix printers permit a choice between output of draft quality; a coarser-looking 72 dots per inch vertically, which may be acceptable for drafts of papers and reports, and near-letter-quality, a crisper-looking 144 dots per inch vertically, which is more suitable for a finished product to be shown to other people.

Dot-matrix printers print about 40-300 characters per second (cps) and can print some graphics, although the reproduction quality is poor. Color ribbons are available for limited use of color. Dot-matrix printers are noisy, inexpensive, and they can print through multipart forms, creating several copies of a page at the same time, which ninimpact printers cannot do.

Another type of impact printer is not used with microcomputers. Large computer installations use high-speed line printers, which print a whole line of characters at once rather a single character at a time. Some, called chain printers, contain characters on a rotating chain; others, called band printers, contain characters on a rotation band. Speeds of up to 3000 lines a minute may be possible with these machines.

Nonimpact Printers

Nonimpact printers, used almost everywhere now, are faster and quieter than impact printers because they have fewer moving parts. Nonimpact printers form characters and images without direct physical contact between the printing mechanism and the paper.

Two types of nonimpact printers often used with microcomputers are laser printers and ink-jet printers.

Laser Printer: Like a dot-matrix printer, a laser printer creates images with dots. However, as in a photocopying machine, these images are created on a drum, treated with a magnetically charged ink-like toner (powder), and then transferred from drum to paper.
- There are good reasons why laser printers are so popular. They produce sharp, crisp images of both text and graphics, providing resolutions from 300 dpi up to 1200 dpi, which is near-typeset quality (NTQ). They are quiet and fast. They can print 4-32 text-only pages per minute for individual microcomputers, and more than 120 pages per minute for mainframes. (Pages with more graphics print more slowly.) They can print in many fonts (type styles and sizes). The more expensive models can print in different colors.

- Laser printers have built-in RAM chips to store documents output from the computer. If you are working in desktop publishing and printing complicated documents with color and many graphics, you will need a printer with a lot of RAM. Laser printers also have their own ROM chips to store fonts and their own small dedicated processor. To be able to manage graphics and complex page design, a laser printer works with a page description language, a type of software that has become a standard for printing graphics on laser printers. A PDL (page description language) is software that describes the shape and position of letters and graphics to the printer. PostScript, from Adobe Systems, is one common type of page description language; HPGL, Hewlett-Packard Graphic Language, is another.

Ink-jet printer: Like laser and dot-matrix printers, ink-jet printers also form images with little dots. Ink-jet printers spray small, electrically charged droplets of ink from four nozzles through holes in a matrix at high speed onto paper.

- Ink-jet printers can print in color and are quieter and much less expensive than a color laser printer. However, they are slower and print in a somewhat lower resolution (300-720 dpi) than laser printers. Some new, expensive ink-jet printers print up 1200 or 1400 dpi. High resolution output requires the use of special coated paper, which costs more regular paper. And, if you are printing color graphics at a high resolution on an ink-jet printer, it may take 10 minutes or more for a single page finish printing.

- A variation on ink-jet technology is the bubble-jet printer, which use miniature heating elements to force specially formulated inks through print heads with 128 tiny nozzles. The multiple nozzles print fine images at high speeds. This technology is commonly used in portable printers.

Things to take into account when buying a printer, is the printer easy to set up? Easy to operate? Do I need color? or black will do? Does the manufacturer offer a good warranty and good telephone technical support? Otherwise it’s wise to own your own personal printer and get to know the answer to these questions.

Have You Filled Your Printer With Printer Cartridge

As a gun needs cartridges to shoot, printer needs printer cartridges to print. Printer is no more a computer accessory. It is no more an optional stuff. Today everyone prefers to go for a printer when they buy a computer. Printer has mostly reduced the hand written reports. Print outs are more preferred, whether in office or in school, as it is more convenient to read and even take less time to write than it is written by hand. But how these printer prints? Printer prints on paper with ink. The ink in these printers is in the form of the printer cartridges. Let us deal with this mystery and reveal it.

There are many types of printers. These are the dot matrix printer, inkjet printer, laser printer etc. Although all of the printers do the same job that is printing, their preferences are varied. Some would like to go for a dot matrix printer as they can print multiple pages through carbon copies while some people may like to go for laser printers as the dot matrix printer are too noisy. Dot matrix printer makes a lot of noise while printing on the paper. Dot matrix printers working are similar to the working of a type writer. Whatever may be the type of printer, printer cartridge is needed. Different types of printer uses different printer cartridges.

Printer cartridge is actually the ink that prints characters on the paper. It is the basic tool for the printer to work. Whether a printer is at home or in office, printer cartridge is essential to make mark on the papers. Printer cartridges include toner, ink refill, ink, and inkjet printer ink and top quality cartridges. Let me give you a technical overview on printer and how does it work? Printers are basically endowed with a flat ribbon that strikes and make an impact on the paper in the form of letters. The ink flows from the storage of ink in the printer to the ribbon. Malfunctioning of the ribbon make the printer disables to print characters on paper. Sometime some letters are missed when such happens.

Printer cartridges should always be selected cautiously. Go for the discounted printer cartridge but never compromise on its quality. Quality printer cartridge can offer you the best performance in printing. There are also color printers that print in colors. Colored printers have different printer cartridges. Printer is playing a vital role in the present economy. The success of your business in a way can depend on the printed paper that is depended on the printer cartridge. Your business document will reflect your efficiency and competence in the business. If your printer cartridge is not good at producing quality printing then it would create a bad impression on you client. It can even risk your deal to be finalized. So always check for the printer cartridge to avoid such redundant situation.

Keep excess printer cartridges in store. While printing some important documents, if your printer runs out of ink, what would you do? You may not have enough time to buy new printer cartridge. So always keep with you printer cartridge in surplus to avoid such situations.

Printer Buying Guide

Printers are essential peripherals, performing a critical role as they render electronic information into tangible records or material output. You’re simply not using your computer to its fullest potential if you are unable to print reports, presentations, letters, photos, or whatever it is you need to output. Choosing a printer can be confusing, however, in today’s competitive, ever-changing landscape. This buying guide rounds out some of the more important criteria to consider before you make that all-important purchase decision.

Printing Technologies

This is the biggest decision to make before anything else. Your choice should be based on how you work and the kind of output you will be expecting from the printer.

Inkjet: Inkjet printers can deliver stunning color, so this is the way to go if you are mostly concerned with printing photos. Inkjets can be used for printing text, but the print speed is too slow if the primary purpose of the printer is document printing. To obtain more photo-realism, choose inkjets with an expanded range of colors that includes light cyan and light magenta in addition to the standard four-color CMYK (cyan, magenta, yellow, and black). The extra colors deliver more subtle color gradations in blue skies and skin tones. And if you print a great deal of black-and-white photos, consider photo printers with more than one variation of black ink or with gray inks. Many photo printers use color inks to produce a composite black, resulting in a muddy tint. A second black-ink cartridge and different shades of gray help maintain a neutral tone, with the gray ink allowing for subtle shading and thus improving the quality of black-and-white photos.

Dye-sublimation: Dye-sub printers can print continuous tones and a superior range of colors that laser printers are unable to, making them ideal for more demanding graphic applications or color printing. Dye-sub prints are also less prone to fading and distortion over time than dye-based ink prints. In addition, many consumer-based dye-sublimation printers can print directly from digital cameras and also accept memory cards. They are, however, more limited in the range and size of printing media that can be used usually letter-size paper or smaller.

Laser: Laser printers are the perfect choice if you need to print large amounts of text documents. They print faster than inkjets and have a lower cost of operation over the long-term even though they may cost more to buy initially. There are trade-offs, however. Monochrome laser printers produce crisp black-and-white text but cannot be used for color printing. Color lasers deliver excellent text and graphics but are much more expensive and can be costly to maintain.

Printer Usage

Some printers are good for general printing, while others are better at specialized tasks or combine several functions into one machine.

Photo: If you take lots of pictures, consider getting a photo printer. Photo printers can be in the form of photo inkjets which can print both photos and text; snapshot photo printers for outputting small 4×6-inch prints; or professional photo printers for large, tabloid-size photos and often including network connections to enable printer sharing. Most consumer and professional photo printers use inkjet technology, while most snapshot photo printers that print 4×6-inch prints rely on dye-sublimation technology. Regardless of the type or technology that is used, the most important thing to look for in a photo printer is photorealistic quality. Everything else is secondary.

General Purpose: As the name implies, general purpose printers can be used for printing almost anything, including text and photos. Choose a general printer with a laser format if you print more text than photos; and choose an inkjet format if you print more photos than text.

Multifunction: Multifunction printers (MFPs) combine in one device several functions such as printing, scanning, faxing, and copying. MFPs cost less than buying separate stand-alone devices and cut down on the hassle of setting up individual machines. If you are strapped for budget or space, consider these all-in-one devices. Take note, however, that a malfunction with one component takes down the whole device, and individual components may not be upgradeable. MFPs are available with either laser printers to emphasize speedy text printing and the occasional graphics output; or they are available with inkjet printers for vibrant photo printing.

Environment and Applications

When deciding on a printer, think about where and how you plan to use it. The home user will have different printing needs from that of the office worker, photographer, or traveler.

General/Basic home use: Versatile, affordable printers are the best choices here, and inkjets usually satisfy the printing needs of most home users looking to output photos from their digital camera or for other light printing needs. Ink cartridges can be expensive, so look for inkjets with separate cartridges for each color. This way, you need not throw out entire cartridges simply because one color has been used up ahead of the others but replace only the ones that run out.

Home office: An MFP may be a great device to have in your home office, especially if it comes with an automatic document feeder that can process multipage documents unattended. Extra onboard memory increases efficiency and allows for processing of larger graphics and documents with ease. And if scanning and photocopying are important to you, get an MFP with a higher resolution.

Photography: Photo printers are the obvious choice if printing photos is your main thing. Choose either the smaller, snapshot photo printer that produces 4×6-inch prints; or choose larger-sized, professional photo printers that are capable of delivering tabloid-size 11×17-inch prints even up to full-bleed 13×19-inch prints that include a border to allow room for registration marks.

Text printing: If printing large amounts of text is what you’ll be doing most, monochrome standard laser printers are your best bet as they can turn out page after page of crisp text fairly rapidly. These printers are ideal for printing black-and-white text and simple graphics, so you may need to get a separate inkjet or photo printer in order to print color photos unless you wish to invest in the more expensive color lasers that can print both black-and-white and color documents.

Small network: A workgroup laser printer can be what you need if your home office or small office is built around a network. Workgroup lasers pack faster print speeds and have more memory to handle multiple print jobs. They also offer more advanced handling capabilities such as larger trays, and may offer duplex (double-sided) printing, sorting, and stapling. More expensive than standard laser printers, the majority of workgroup lasers are monochrome designed for printing text and simple graphics.

Traveler: For the businessperson on the go and looking to print, portable printers provide the solution with their compact size (small enough to fit into a briefcase), light weight (less than 5 lbs.), and handy power (operates on batteries or with a car charger). Newer models can print wirelessly making it a non-issue if you forget your USB cable at home. Some portables offer great extras such as a sheet feeder for automatic page feeding, are able to handle transparencies and envelopes, and even support an optional scanner cartridge that replaces the ink cartridge and turns the printer into a scanner. Portable printers are more expensive and print more slowly than standard printers, but convenience is what you’re paying for.

PC-free printing

With something called PictBridge support, photo printers do not need to be connected to PCs to be able to print photos. PictBridge is a standard adopted by manufacturers of printers and digital cameras for PC-free printing, allowing photos to be printed straight from the digital camera to the printer by simply connecting them through a USB cable as long as the printer and digital camera are compatible. A variation to this idea is the ability for printers to read memory cards directly from a digital camera or other image-storing device by simply inserting the cards into designated printer slots.

Once the camera is connected to or the card is inserted into the printer, photos can be reviewed in a number of ways, depending on the printer model. Some may feature a built-in LCD screen that allows shots to be reviewed, edits to be made, and the ones to be printed chosen directly from the screen. Other models may let you create an index sheet similar to a contact sheet in film printing so you can mark the ones you choose for printing and rescan the sheet. Other printer models let you decide which shots you want to print straight from the digital camera. Many types of memory cards are available on the market today, so make sure the printer accepts the kind used by your camera for you to enjoy card-direct printing of photos.

Paper Handling

Paper is obviously an important issue in printing. Here are some important tips on paper handling for printers:

When buying a printer, make sure that it’s equipped to accommodate all the paper sizes and types that you’ll be using. If you need to print on heavy stock, for instance, make sure the printer can handle the heaviest paper you use. For this purpose, a printer’s paper path can give an indication of how it handles paper: Inkjets generally use straight-through paper paths, while lasers use S-shaped or U-shaped paths. Generally speaking, the straighter the path, the thicker the media that can be used. However, the curved paths typical of laser printers also makes it possible to have more flexible configurations for input and output trays.

Using the correct type of paper will also make a difference to your printing. Inkjets can print on a variety of matte or glossy photo paper, but make sure you choose the right kind of paper for your printer to obtain optimal print results. For example, matte papers are suitable for both pigment and dye-based inks, while luster finishes are generally more suitable for dye-based inks.

In terms of size, most inkjets and lasers can handle printing of letter and legal sizes. If you need to print larger prints, however, consider a printer that can handle sizes like 11 by 17 inches. You may also consider getting a printer with multiple paper drawers if you’ll be switching between different paper sizes on a regular basis. For a laser printer, multiple output trays, duplexing (double-sided printing), collating, and automatic stapling can be additional useful features.

If you plan to use third-party paper, make sure it works well with your printer. Before you buy a large quantity of third-party paper, try a few samples by printing the same photos on both the printer manufacturer’s paper and the third-party paper, and then compare the results.

Printer Specs and Key Features

Printers feature various specifications, so navigating the spec sheet intelligently requires familiarity with what each specification entails according to the printing technology involved or for the type of usage planned for the printer.

Resolution: For laser printers, 300 dpi is adequate if all you need is to print black-and-white text, but choose at least 1200 dpi for photorealistic grayscale or color printing. For inkjets, choose one featuring 1200-dpi or higher resolution with a droplet size of 4 picoliters or smaller for sharp, clean output. With photo printers, resolution varies according to technology: Output at 300 dpi by photo printers using dye-sublimation technology is comparable to photo printers using inkjet technology outputting at 1200 dpi or higher.

Speed: Speed ratings vary greatly, and the print speeds cited by manufacturers usually refer to printing in draft mode or at the lowest resolution. For laser printers, a more accurate way of measuring actual print speed is to time just how long it takes from the minute you hit “Print” to the time that it takes the printer to warm up, spool the job into the print queue, and for the printed output to finally come out. For inkjets, print speed is not one of its stronger suits; so don’t be overly concerned with this spec.

Memory: Extra memory will come in handy for laser printers to enable them to handle large graphics and documents more easily. Check the maximum upgradeable memory allowed for your printer, if it features a hard drive with similarly upgradeable memory, and if the printer can use generic memory or needs the manufacturer’s brand. In the case of inkjets, memory is built-in and not upgradeable, but this is not an issue inasmuch as processing occurs on the side of the computer so there’s no need for large amounts of installed RAM to begin with on inkjets.

Connectivity: Most printers today no longer support the older parallel connection but feature instead USB 1.1 or Hi-Speed USB (USB 2.0) either of which should work fine with USB computers. For printers to be used on a network, it will need to have an Ethernet port to enable printer sharing. For more flexible printing options, you may want to look for printers with infrared input/output ports that allow wireless printing from notebooks or other devices with infrared ports. And if high-speed or long-distance printing is what you need, consider printers with a FireWire port.

Consumables and cost per page

The purchase price of the printer is just the beginning of its overall cost because over time, the hidden cost of ink or toner, paper, and parts will add up. These “hidden costs” are the consumables; dividing the total cost of consumables by the number of pages that can be produced from the consumables gives you the cost per page. Laser printers offer the lowest cost per page, using relatively inexpensive toner and normal-weight, uncoated paper. On the other hand, cost per page for inkjets can be four or five times as much, depending on how much ink you use and the cost of the paper normally more expensive, coated, glossy paper for higher-quality color output. The tank configuration for inkjets should also be taken into consideration. Inkjets with a single cartridge for the colored inks will incur higher replacement costs because the cartridge must be replaced as soon as one color runs out even if the cartridge still contains plenty of ink for the other colors. To save costs, get an inkjet with separate cartridges for black and each individual color.

Print Quality

All the specs and fancy features in your printer won’t mean a thing if you don’t have good, solid print quality whether of text or photos to back it up.

Text: Text should be smooth and crisp. At the smallest font sizes, the individual letters should be clearly readable, and they should not bleed into one another. Medium-size fonts should have no fuzzy edges, and the largest fonts especially bold ones should be filled with solid black, not a muddy brown or bluish tone. You should also be able to see well-formed and well-rounded counters (the openings) in letterforms; if you don’t, it’s usually a sign of the printer laying down too much ink. (Remember, however, that inkjet printers will display some wicking on plain, 20-lb. paper, as the ink bleeds along the paper fibers.)

Graphics: For color printing, look for gradients or areas where a color goes from dark to light. Color should transition smoothly, and you should not see any color banding, where distinct bands progress from dark to light. On a test page, you will likely see a gradient bar that goes from black to white through a series of progressively darker gray shades; the transition from shade to shade should be smooth without a noticeable line. Also, look for a nice balance of colors in color-graphic printing something that’s not overly saturated nor flat and washed out.

Photo: A good photo print should like the original photo. Colors should be accurate and balanced, vivid but not oversaturated. Good detail should be present in all areas, with no jagged lines or pixels or any other visual artifacts. Good contrast should exist between shadow and highlight areas not muddy or flat and without color. You may not always be able to tell the difference from one great print to another, but almost everyone can recognize a bad print when they see one. Trust what you see.
