Laptops Battery Life
The battery life and the laptop battery care is another most important topic which one must have to care so as to have longer battery life. Normally the batteries which the manufacturers provide with the Laptops are Li-Ion or Li-Polymer these are rechargeable batteries and can give you optimum backup even you are working on battery packs. But the main thing is tat how to optimize it to make it work more efficiently.
The common term when we talk about Battery in Laptops is the Depth of Discharge (DOD). Depth of Discharge (DOD) is the amount that a battery is run down to before it is put back on charge. For a notebook this can vary enormously. Many machines are only run down to 70% battery during short stints of battery power (known as a shallow DOD), others are discharged completely to 10% or 5% (known as deep DOD), this is when the notebook switches off or warns about low battery.
Now another technical aspect is the charge cycle. A charge cycle is a cycle of running the battery down and then charging it up again. One charge cycle is classified as when the battery is run down to 70% or less and then charged again to 90% or more. A battery does not have to be discharged until it is flat before a charge cycle is used.
The other main factor that affects battery life is temperature, the hotter the battery the less charge cycles it will run for, the industry suggestions are that a battery is run at between 10 and 30 degrees centigrade. It should be noted that it may be hotter inside the notebook where the battery is than in the room where it is being used.
The battery life and rechargeable ability of a particular type of batteries like Li-Ion varies but these are more than enough for you before going for its replacement. Always try to have a look at your battery packs how much backup they provide and time of full charge. This is done so as to check if the batteries are becoming old or demanding for the replacement or what. If possible always try to use Power Supply while working on Laptops.
Always carry with you an extra battery pack so as to use it when you are traveling and where it is not possible to lug in to the Power Supply. If you have found that the batteries has gone old then immediately replace it with new one and never keep the old batteries in the Laptop thinking of buying the new one. This will damage your internal circuit.

The different types of dell laptops are
1. Ultraportables:Laptops have screens typically less than 12 inches diagonally and weigh less than 1.7kg. Their primary audience is usually business travelers who need small, lightweight laptops. Ultraportables are often very expensive and house power-saving CPUs and almost always have integrated graphics.
2. Thin-and-lights:These are the Laptops which weigh between 1.8kg and 2.8kg with a screen size of 12 or 14 inches diagonally.
3. Medium-sized laptops:These are usually having screens of 15 - 15.4 inches diagonally and weigh around 3-3.5kg.
4. Desktop replacement computers:These are powerful laptops mainly used in a fixed location and infrequently carried out due to there weight and size. They provide more space for powerful components and a big screen - usually measuring 15 inches or more for desktop replacements and often have limited battery life due to their hardware, rarely exceeding three hours.
Dell manufactures its products close to the customers. The assembling of desktop computers for the North American market takes place at Dell Laptops plants in Austin, Texas and in Winston-Salem, North Carolina with servers built in Nashville, Tennessee. Dell, Inc. assembles computers for Europe in Limerick City, Ireland. The major competitors of Dell are Apple, Hewlett-Packard/Compaq, Packard Bell, Sun Microsystems, Gateway/Emachines, Lenovo, Sony, Toshiba, and MDG Computers in Canada. Enthusiast market competition takes place with Alienware, now which is a Dell’s division- Falcon Northwest, Voodoo PC, WidowPC, Sin Systems Inc. and other manufacturers. By August 2003, Dell Laptops lowered their product prices by 22% in an attempt to generate more sales; however this disappointed shareholders, sending it shares down by 2% in late Wall-Street trading, amid fears of a sector-wide slump.

Information on Used Laptops
Used laptops are those that have been used by a consumer for a length of time and then they are resold for a number of reasons. Used laptops offer the potential savings of hundreds of dollars over a new laptop. Used laptops are a cheaper alternative to buying new, and are a great investment for a laptop capable of performing many tasks. Used laptops are just like used cars you need to check them out and be sure of what you are purchasing first. Used laptops are for the most part are a good value for the money.
Buying
Buying from eBay, smaller used laptop websites and other shops or the classifieds can be successful; you just need to know what to look for. Buying a used laptop allows you to pick up technology which is still in use today although it may not have the most recent operating system. Buying a refurbished laptop doesnt mean youre stuck with an outdated machine, as most of the refurbished units will be updated with some of the most current technologies today. A refurbished laptop is an excellent choice if you are not comfortable with buying a used laptop plus the do come with a warranty.
Price
A number of certified dealers trade in eBay, Amazon and Yahoo stores, offering very tempting prices for used laptops. Regardless of the brand, medium priced used laptops in the range of $500.00 to $650.00 are considered good money savers for those who do not require using the fancier laptops. You can for instance get a laptop without wireless capabilities at a better price, and you can add a wireless card to your laptop and save additional money. You should be considering used laptop or refurbished laptop which can get you most if not all the features you want, without paying full price. The brands named laptops tend to have higher prices for the same features as some of the less popular brands.
Used laptops are perfect for students doing homework, a professional that only needs to operate a few programs, or for someone who just wants to access the internet without the bulk of a desktop. They are perfect for people wanting to use a mobile computer for only a couple of applications, but still want the mobility of a laptop. Used laptops are sold for a number of reasons one of the reasons might be due to purchase of a higher configuration laptop, or might be tired of using the laptop for some time and would just like to have a newer one. Used laptops are a viable option to own a laptop at if you are on a tight budget.

About Cheap Laptops
By Victor Pradel
There are many things to consider when choosing one right cheap laptop piece for you. We should take an informed choice when buying our next laptop computer.
Notebooks come in all sizes and shapes with a variety of features to suit almost any task. Before we begin searching the internet for the lowest priced machine on the market, it is a good idea to think how it will be used because choosing the right one very much depends on its intended use.
Compile a list of features in order of preferences i.e.
1) must haves
2) would likes
3) bonus features
Now you are ready to search within your budget for ideal cheap notebook. For example, Tim is a web developer, he spend lots of time playing with code, w4e use graphics packages to design sites and text editors to code them. So, he would require a wide screen, good graphics and a dual core processor for multi tasking, at least 1 GB of RAM, 80 GB minimum disk drive and Wi-Fi, so he can site and work in park on a nice summers day.
The general order of things would be CPU, Memory, Graphics, Screen size and type, Hard drive capacity aiming to get the best of each then looking to see what other bonus features we can fit within our budget.
Users of cheap laptops will have lot many problems. Most of the users buy cheap laptops get lesser GB drive than the originally stated GB. Where has the missing space gone for which amount was paid?
The answer to this question is perhaps that the operating system reports the capacity of the hard drive using the assumption that l MB is equal to 1,048,576 bytes. This is technically correct. But the hardware manufacturers compute the size a bit differently. They consider 1 MB to be equal to 1,000,000 bytes.
Therefore, we can see how this can cause confusion. If the drive is advertised as 20.00 GB i.e. 20,000,000,000 bytes, the operating system will see it as approximately 19.07 GB (20,000,000,0000 / 1,048m576 / 1000 = 19.07). The full 20,000,000,000 bytes are really there. Courtesy to them.
Laptop prices now start at a very lesser price. While reviewers cite a number of catches to bottom of the line notebook computers, you can get a fully functional laptop for less amounts. If your notebook will supplement a desktop PC or you need no applications more demanding than word processing, web browsing, or mail, a cheap notebook works just as well as one that costs twice as much.
But of course if you want to get some combination of better build quality, a longer warranty, an easier-on the eyes display, longer battery life, gaming capability and lighter weight you have to spend more.

How to fix video problem on HP laptops
How to fix video problem on HP laptops:
In this post I explain how you can fix a known video problem on some HP laptops without actually taking it apart. Most likely the fix is not permanent but this will buy you some time, enough to backup personal files or even use the laptop until you get a new one. There is no guaranty this fix work 100%.
Here are some HP models affected by this known video failure problem: HP Pavilion dv2000, dv6000, dv9000, tx1000 tablet PC, Compaq 700, v3000, v6000 and probably some others.
If you know more models, please mention them in comments after this post.
I found this trick mentioned by Walliot (comment 85) in this post. This trick called “towel fix” and used to fix “no video” issue in xbox360.
2. Plug the AC adapter and turn on the laptop. Make sure the laptop is actually on, all LEDs should work.
3. Wrap the laptop with towels so all air intakes are closed.
4. Keeps the laptop wrapped in the towel for about one hours.
5. Unplug the AC adapter from the wall the let the laptop cool down (do not touch it for a while).
6. Unwrap the laptop and try tuning it on.
I didn’t really believe that this trick might work and tried it just because of curiosity but… IT WORKED!!!!
LAPTOP #1. HP tx1000 Tablet PC.
First, I tried this fix on a failed HP tx1000 Tablet PC.
I didn’t have paper towels at work but I had plenty of bubble wrap.
I closed the laptop in a tablet mode (with hard drive and battery removed), plugged the AC adapter and wrapped the laptop properly in bubble wrap.
After that I just waited for about two hours and unplugged AC adapter from the wall.
Waited for about 30 minutes and tried turning it on.
Success!!! The laptop started with video.
I just couldn’t stop and tried the fix on another failed laptop.
LAPTOP #2. HP Pavilion dv6000.
This is a different model with very similar failure symptoms. It turns on, all LED lights work but there is no video.
This time I didn’t something extra. To make sure there is no cool air coming into the laptop though bubble wrap, I closed all air vents with sticky tape.
After that I turned on the laptop from AC adapter (again with hard drive and battery removed) and wrapped the laptop base with bubble wrap.
The laptop was running like that for about 60-70 minutes but then I noticed that all LED lights went off. Not sure what happened, maybe the laptop overheated too much and shut down on its own. Anyway, I didn’t touch it for about 30 minutes and let it cool down.
My fix was successful again! The laptop turned on with video and booted to the desktop.
When you run a laptop wrapped in towels (bubble wrap in my case), it gets very hot because there is no air circulation inside the heatsink. The heatsink and GPU (NVIDIA chip) run so hot that it melt solder between the chip and motherboard and the video chip gets resoldered to the motherboard.
Now I have to test for how long this fix last.
In one of the following posts I explain how to reflow failed NVIDIA graphics chip with a heat gun.

CAUSE OF THE PROBLEM:As I know, the video problem somehow related to NVIDIA chip located on the motherboard. Overtime the NVIDIA chip separates from the motherboard and the laptop video fails.
SYMPTOMS OF THE PROBLEM:When you turn on the laptop, all LEDs light up but there is no video on the laptop screen or external monitor. The laptop screen remains completely black and blank. The cooling fan spins as normal, on some models it stars spinning right away on other models after some time.
I found this trick mentioned by Walliot (comment 85) in this post. This trick called “towel fix” and used to fix “no video” issue in xbox360.
HOW TO FIX:1. Remove laptop battery and hard drive.
2. Plug the AC adapter and turn on the laptop. Make sure the laptop is actually on, all LEDs should work.
3. Wrap the laptop with towels so all air intakes are closed.
4. Keeps the laptop wrapped in the towel for about one hours.
5. Unplug the AC adapter from the wall the let the laptop cool down (do not touch it for a while).

HOW THIS FIX WORKS:Here’s my understanding of how this fix works.
When you run a laptop wrapped in towels (bubble wrap in my case), it gets very hot because there is no air circulation inside the heatsink. The heatsink and GPU (NVIDIA chip) run so hot that it melt solder between the chip and motherboard and the video chip gets resoldered to the motherboard.
