Laptop Batteries and Laptop Battery Care

Laptop Batteries are essential for keeping a laptop running properly. In many cases, businesses, whether personal or corporate, depend on laptops for business dealings day to day. There are a number of ways to properly care and maintain a laptops main power source, the battery. Battery construction of laptop batteries is very different from other traditional electronic device batteries. A brief overview of the construction of laptop batteries will help provide insight into factors that affect the life and care of laptop batteries.

Laptop batteries are constructed with a number of crucial components to regulate charge and power supply to the laptop. A thermistor measures the charge of the battery and regulates how much charge the laptop sends to the battery. When the battery is fully charged, the thermistor tells the laptop to stop charging. Safety fuses and breakers in the laptop battery also help prevent overcharging and aid in overall functionality of the laptop battery. So there is an essential communication that must occur between the components of the laptop battery and the laptop itself to ensure proper function of both the computer and the power supply.

Laptop batteries are becoming more advanced that other types of batteries. In the past they were constructed of NiCd or NiMH which provided less power and did not recharge well. Lithium polymer batteries are the newest revelation in battery technology and they are leaps and bounds beyond old metal batteries. They provide the right amount of power and charge in a fraction of the time of metal batteries. The advantages of lithium batteries make new laptop batteries more practical. Lithium batteries therefore help improve the life of laptop batteries and also make them a more valuable battery for the money.

There are a number of precautions to take to ensure safe and practical function of the laptop battery. Some laptop batteries can become overheated from charging which can create a fire hazard. It is important to place the laptop battery in a location that is free of flammable objects such as paper or furnishings. In general, it is good to avoid extreme temperatures for proper optimal function of a laptop battery. Battery life of a laptop battery depends greatly on how the laptop is used. A laptop battery will not last very long without being charged. A useful method to extend battery life is to close as many unnecessary programs as possible. By closing programs that will not be needed will save useful battery life.

These are just a few pieces of information about laptop batteries that will help the user understand how to care for laptop batteries and how to manage laptop battery life. There is much more information about laptop batteries, including battery construction, battery charging and much more.

Simple Ways To Speed Up Your Windows XP

1. Defrag Disk to Speed Up Access to Data

One of the factors that slow the performance of the computer is disk fragmentation. When files are fragmented, the computer must search the hard disk when the file is opened to piece it back together. To speed up the response time, you should monthly run Disk Defragmenter, a Windows utility that defrags and consolidates fragmented files for quicker computer response.

* Follow Start > All Programs > Accessories > System Tools > Disk Defragmenter
* Click the drives you want to defrag and click Analyze
* Click Defragment

2. Detect and Repair Disk Errors

Over time, your hard disk develops bad sectors. Bad sectors slow down hard disk performance and sometimes make data writing difficult or even impossible. To detect and repair disk errors, Windows has a built-in tool called the Error Checking utility. It’ll search the hard disk for bad sectors and system errors and repair them for faster performance.

* Follow Start > My Computer
* In My Computer right-click the hard disk you want to scan and click Properties
* Click the Tools tab
* Click Check Now
* Select the Scan for and attempt recovery of bad sectors check box
* Click Start

3. Disable Indexing Services

Indexing Services is a little application that uses a lot of CPU. By indexing and updating lists of all the files on the computer, it helps you to do a search for something faster as it scans the index list. But if you know where your files are, you can disable this system service. It won’t do any harm to you machine, whether you search often or not very often.

* Go to Start
* Click Settings
* Click Control Panel
* Double-click Add/Remove Programs
* Click the Add/Remove Window Components
* Uncheck the Indexing services
* Click Next
4. Optimize Display Settings

Windows XP is a looker. But it costs you system resources that are used to display all the visual items and effects. Windows looks fine if you disable most of the settings and leave the following:

* Show shadows under menus
* Show shadows under mouse pointer
* Show translucent selection rectangle
* Use drop shadows for icons labels on the desktop
* Use visual styles on windows and buttons

5. Speedup Folder Browsing

You may have noticed that everytime you open My Computer to browse folders that there is a little delay. This is because Windows XP automatically searches for network files and printers everytime you open Windows Explorer. To fix this and to increase browsing speed, you can disable the “Automatically search for network folders and printers” option.

6. Disable Performance Counters

Windows XP has a performance monitor utility which monitors several areas of your PC’s performance. These utilities take up system resources so disabling is a good idea.

* Download and install the Extensible Performance Counter List(http://www.microsoft.com/windows2000/techinfo/reskit/tools/existing/exctrlst-o.asp)
* Then select each counter in turn in the ‘Extensible performance counters’ window and clear the ‘performance counters enabled’ checkbox at the bottom button below

7. Optimize Your Pagefile

You can optimize your pagefile. Setting a fixed size to your pagefile saves the operating system from the need to resize the pagefile.

* Right click on My Computer and select Properties
* Select the Advanced tab
* Under Performance choose the Settings button
* Select the Advanced tab again and under Virtual Memory select Change
* Highlight the drive containing your page file and make the initial Size of the file the same as the Maximum Size of the file.

Windows XP sizes the page file to about 1.5X the amount of actual physical memory by default. While this is good for systems with smaller amounts of memory (under 512MB) it is unlikely that a typical XP desktop system will ever need 1.5 X 512MB or more of virtual memory. If you have less than 512MB of memory, leave the page file at its default size. If you have 512MB or more, change the ratio to 1:1 page file size to physical memory size.

8. Remove Fonts for Speed

Fonts, especially TrueType fonts, use quite a bit of system resources. For optimal performance, trim your fonts down to just those that you need to use on a daily basis and fonts that applications may require.

* Open Control Panel
* Open Fonts folder
* Move fonts you don’t need to a temporary directory (e.g. C:\FONTBKUP?) just in case you need or want to bring a few of them back. The more fonts you uninstall, the more system resources you will gain.

9. Use a Flash Memory to Boost Performance

To improve performance, you need to install additional RAM memory. It’ll let you boot your OS much quicker and run many applications and access data quicker. There is no easiest and more technically elegant way to do it than use eBoostr (http://www.eboostr.com).

eBoostr is a little program that lets you improve a performance of any computer, powered by Windows XP in much the same way as Vista’s ReadyBoost. With eBoostr, if you have a flash drive, such as a USB flash thumb drive or an SD card, you can use it to make your computer run better. Simply plug in a flash drive through a USB socket and Windows XP will use eBoostr to utilize the flash memory to improve performance.

The product shows the best results for frequently used applications and data, which becomes a great feature for people who are using office programs, graphics applications or developer tools. It’ll surely attract a special attention of laptop owners as laptop upgrade is usually more complicated and laptop hard drives are by definition slower than those of desktops.

10. Perform a Boot Defragment

There's a simple way to speed up XP startup: make your system do a boot defragment, which will put all the boot files next to one another on your hard disk. When boot files are in close proximity to one another, your system will start faster.

On most systems, boot defragment should be enabled by default, but it might not be on yours, or it might have been changed inadvertently. To make sure that boot defragment is enabled:

* Run the Registry Editor
* Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Dfrg\BootOptimizeFunction
* Set the Enable string value to Y if it is not already set to Y.
* Exit the Registry
* Reboot

Hope you find these 10 tips useful. Have a nice day!

Advantages of Buying Refurbished Laptops

Laptops can be sent back to the manufacturer if the purchaser finds the screen of the laptop scratched or with a minor blemish, or if it is an unwanted present to him or if the packaging of the laptop is dented etc. Such laptops are inspected, tested again for quality and repackaged by the manufacturer and sold for a very less price. Such laptops are called as refurbished laptops.

Factory refurbished laptops:

The laptops in the factory undergo rechecking for any manufacturing defect by passing through various stages of examination. Then, when no fault is found, the hard disk of the laptop is reformatted and again the operating system is loaded. It is again made to work for less than 4-5 hours time to check for any defect and the parts are replaced if they are found to be defective. The refurbished laptop is then updated with a new serial number to mark it as a factory refurbished laptop. Such factory refurbished laptops are of high quality available to the consumer at a lesser retail price. Such refurbished laptops can be got from almost all the renowned brands. However the process carried out for the restoration of laptops may differ from company to company. The main aim is to make the laptop run again efficiently as it used to be previously.

Custom refurbished laptops:

These are repaired laptops which are reassembled to match the customer’s preference. It gives an opportunity to get a complete laptop solution at a very affordable price to the customer. The utilities offered by the customer refurbished laptops are got at a cost of a used laptop. It also avoids the necessity to upgrade immediately, which is not the case with the standard laptop. It allows the customers to have preferences in terms of selecting the features like the screen size, processor speed requirements, multimedia, memory capacity, hard drive size, optical drive, graphics, accessories, Bluetooth etc.
When purchased in bulk, custom refurbished laptops are the best option as it combines both functionality and price advantage together. Additional benefits can be availed through promotional offers and discounts from the manufacturers.

Advantages of purchasing refurbished laptops:

The refurbished laptops are of high quality as they are checked for high standards of performance at each level of examination done.

More over discounts are offered to military personnel, senior citizens and students who can maximize their savings by purchasing a refurbished laptop. The refurbished laptops can be selected from renowned brands available in the market at a lesser cost. Such refurbished laptops are also got with 1 year warranty which can be extended up to 3 years. The warranty period supports replacement of parts and maintenance required by the laptop. Hence purchasing such laptops are very reliable. The refurbished model laptops enable the customers get more features at a lower cost. When the purchaser is bent on buying the latest, trendiest laptop, but cannot afford to buy a new one he can go for a refurbished laptop to get satisfied.

About Laser Printers

Like with many other things in the world of printing, laser printers have come a long way in the past few years. They have gone from being found almost exclusively in offices to being offered at $100 for a home user. Although they are better for a lot of people, some have a hard time imagining themselves buying a laser printer for their home. A lot of people have the idea that laser printers are just the big clunky machines in their offices where the toner cartridges cost a fortune. However, if you are someone who prints out a large amount of documents and is tired of always having to buy new black inkjet cartridges, laser printers can be the solution. Once you get past the initial sticker shock of buying laser toner cartridges, you will realize the numbers for an entry level laser printer versus an inkjet printer look something like this:

Typical toner cartridge - $50-$60
Page yield - 2,000-3,000 pages
Average cost per page - 2-2.5 cents per page

Typical inkjet cartridge - $20-$30
Page yield - 400-500 pages
Average cost per page - 4-6 cents per page

Although these are just averages and may not seem all that different, in general if you are printing documents, it will probably cost you twice as much to run an inkjet printer than a laser printer. It is better to think of things in the long term when it comes to laser printers, because only then will you truly appreciate their value. If you buy a laser printer and then a backup toner cartridge at the same time, by the time you will have finished that second cartridge, you would have gone through roughly 10 inkjet cartridges.

So if you aren't into printing color, then you are probably better off going with a laser printer over a standard inkjet printer. You will appreciate the speed and low maintenance of a laser printer, while also saving money on printer ink in the long run.

Barebones Computer Buying Tips

Getting a new computer should be a cool thing, especially a cheap computer. After all that time struggling with you old machine, probably fighting with it to get the latest software to run, your new computer should be a ray of light for your computing future.

Oh, if it were that simple. If things were really that easy or simple when buying a cheap computer, life would be much easier, but just like every other thing, its not that simple.

Barebones computers have become extremely popular, and for good reason. Getting a barebones computer which does not include a monitor and comes with the bear minimum of parts makes them an upgradable, practical and cheap computer.

But not all things are rosy in barebones computer land...

1. Missing parts

Although barebones computers do come with the essential pieces, most people need at least one or two extras for their day to day barebones system. This is simply due to different applications people use them for. Don't get caught missing that extra part from your barebones system that you then need to get later. You still need to do some homework and research to find out what you really need from your barebones system.

2. Super cheap computer deals

Beware, many corners can be cut to get those sub $200 dollar barebones systems. They can be great, but not always, carefully analyse the components of the package. Also remember that a barebones system couldn't possibly include a monitor for that price, which adds a lot to the price.

3. Mismatched parts

This could become a problem if building your own computer, but it even happens in pre-assembled barebones computer deals. There is a chance that you get something that doesn't fit with the barebones system. There are lots of different connections and speed ratings between parts. Make sure the ones you get match up to the other parts and your needs. Although not common, incompatibilities between parts are not unheard of.

4. Outdated components

To get super-cheap deals older parts are sometimes used in cheap computers. Although this can be a great cost-saver and some old parts are fantastic, there is nearly no chance of an upgrade without putting a major amount of money into your barebones computer again, perhaps as much if not probably more than you paid for your great deal.

5. Defective parts

Although this is another one that has gotten better as the competition has gotten stronger, there is a chance of defects in cheaper products. Your motherboard could be faulty, your power supply might give up after a month or two. These may not be intentional problems, but come hand in hand with "cheap computer stuff".

6.Refurbished computer parts

Refurbished computer parts are a great way to save some money. Not always the biggest saver, but there can be problems with the updates to these computers in much the way as mismatches happen in barebones systems. Often the computer is slightly updated to meet needs, but is really quite an old model, just with upgrades. Can be fine, but the parts they replace might be replaced with something newer but inferior.

7. Claims of great warranty

To try and entice you into feeling safe, offers of long warranties are made. Most of the parts in the computer could have past their warranty dates, so the warranties are purely from the company that put the computer together. They can be hard to contact and take their time to get replacements to you as well as expect you to mail the computer to them so that they can do the repairs.

Barebones computers can be a great way to put together a second computer, build a computer for simple purposes, like writing documents and casual web surfing. Barebones fit perfectly as a second computer. Just keep these things in mind and you won't get bitten by the bargain bin monster.

Reasons To Remove Spyware From Your Computer

Is your computer been running slower than normal? Are you worried someone may be able to access your computer and steal your private information and use it against you? If so, these are feelings I have shared with you in the past.

Some time back, my 3-year old computer was running so slow that I had to buy a new computer. Or at least I thought I needed a new computer. Then within a matter of weeks of surfing on the Internet, my new computer was also running so slowly. In addition, some programs did not run well on my computer, and I did not recognize some of the programs that were running on my computer. That scared me most. Were these programs that were tracking my keystrokes on my computer or programs I just not remember installing? I knew I had to find a answer and solution fast.

The truth is, we can all put up with a slow computer, but very few of us would want others to have access to the information on our computers, but that is exactly what can happen when spyware or malware is loaded on our computers without our knowledge.

According to Spyware Nuker’s web site, “Spyware applications are programs and files that hide on your PC's hard drive without your direct knowledge. These programs allow hackers and advertising companies to track your every move, both online and even when you work offline. They can track the websites you visit, the items that you buy online, the emails you send and receive, your Instant Message dialog, and worst of all they can even record your credit card number, personal identification numbers, and all of your passwords. If you use dial-up to connect to the Internet then spyware can be used to bill 900 numbers to your phone bill. This is just a short list of the harm that spyware can cause.”

The web site also provides statistics that show spyware is a huge problem effecting many people. "27.3 million Americans have been victims of identity theft in the last five years, including 9.91 million people or 4.6% of the population in the last year alone."

In addition, it is very easy for your computer to become infected with spyware as "The majority of all downloadable games, music, screensavers, etc., can infect your computer with SpyWare or AdWare. Most people do not know that after simply clicking on a random "pop up" ad, their computers may have been infected with SpyWare or AdWare."

No matter how we get spyware, here are 10 very real reasons you don’t want spyware on your computer.

1. Your computer may start running slower
2. Some programs on your computer will not run correctly
3. You may not recognize programs that are now on your computer because they may have been installed there by a spyware related web site or program you loaded on your computer.

In addition, you might be worried that:

4. Someone might be able to read your e-mails
5. Someone might be able to access your e-mail list
6. Someone might be able to see you track the keystrokes you type
7. Someone might be able to access your credit card information on your pc
8. Someone might be able to access your passwords list on your computer
9. Someone might be able to steal your social security number
10. Someone might be able to track all the web sites you visit

As I mentioned, most of these programs get on your computer with out you even knowing, but another frustrating part is I recognized a few of these programs because I remember installing AND uninstalling them! So now I know that when we install some of these handy little utilities to track passwords online or programs to help with e-mail or keep track of the weather, even if we uninstall them, they may not be gone from our computers. They are still in our computers, waiting to spy on us, at the least.

A great way to find and remove spyware is to run a spyware detector and remover. Most spyware detection and removal software today offers a free scan to verify that you do or do not have spyware on your computer.

Speed Up Your Computer’s Performance

We live in a fast paced world and we’re always looking for the fastest way to get things done. We barely have time to wait for our burger at the local fast food restaurant, our coffee to brew, our microwave popcorn to pop, so who has time to wait around for a slow computer?

Barring adding more RAM to your computer, there are 6 steps you can take to speed up your computer’s performance. Most of these steps will allow you to speed up your computer, free of charge since they are applications already installed on your computer.

One of the first steps you should take is to empty the Recycle Bin. It’s easy to do. Just point your cursor to the Recycle Bin icon on your desktop, right-click, and choose “Empty Recycle Bin.”

Next, open up your Internet Explorer, go to Tools, Internet Options. Click on “Delete Cookies,” then on “Delete Files.” In the window that appears, check “Delete all offline content” and click OK. Once that’s done, click OK to close the Internet Options window, and close your Internet Explorer.

Those two are steps are the quickest, and simplest ones so that’s why we got them out of the way first. Next, we’ll be conducting a Disk Cleanup. To do this, click on Start, All Programs, Accessories, System Tools, Disk Cleanup. The disk cleanup function will now begin calculating how much space you will be able to free up. Once it finishes, it’ll give you a list of files to delete. It should already have some files checked, but you can go through the list and check off all the files you want to delete, then click OK.

Now it’s time to do a disk defragmentation. This can be a long process so you should probably set this up during a time when you’ve got other things going on. For example, set it up, then go watch your favorite TV show, or go mow the lawn, or go workout. You get the idea. To begin go to Start, All Programs, Accessories, System Tools, Disk Defragmenter. Click Analyze. If you’re lucky, you’ll get the “You do not need to defragment this volume” call-out, but more than likely, you’ll have to click on “Defragment.” If so, click on it, go do something else and come back in an hour or two.

Once that’s done, it’s time to run a spyware scan. Most people don’t realize how easy it is to get infected with spyware, so running periodic scans is highly recommended. You can use any anti-spyware program you choose. Just be aware that no one program gets rid of everything. To play it safe, you should run at least three different programs. You might be surprised by what they find. You may have had spyware running on your computer and not even know it. Once the scans are complete, and all that spyware is taken care of, it’s time for the last step.

This last step is to run an anti-virus scan. Hopefully you have an anti-virus program installed on your computer. If not, I highly recommend you get one as soon as possible. Once the anti-virus program is set, go ahead and run it. This could take anywhere from 20 minutes to a couple hours depending on how many files you have on your hard drive so once again, set it, and then go do something else. Come back in about an hour.

Once all the steps are complete. Restart your computer and you’ll be surprised at how completely nimble it now feels. It’s a good idea to follow these 6 steps at least once per week (some steps you can even set up to be done automatically). By doing this, you will keep your computer performing almost like it did when you first bought it.
