Hi all, I begun to experience the issue with battery life. I went from having three hours of battery life on Widnows XP which was running on my lap-top befoure to about 20 minutes on Windows 7 in couple weeks. Windows 7 spits out the following warning message: "Consider replacing your battery. There is a problem with your battery, so your computer might shut down suddenly." I don't see how my battery can decrease it's life over such a short periude of time, considering that I don't havely use the battery max 5-6 hrs per week.Does anyone knows how to workaround this issue before I buy the new battery that I hope wouldn't following the first one to an early grave. Thanks in advance.

Just to be ensure, you can download other Linux, such as Ubuntu and just using LiveCD, see how can your battery last at there. If this still happens on Linux, then it is your hardware problem. Your battery is probably not in a good condition due to several possible reasons.. If this problem only happens on your Windows 7, there must be some patch for it on your manufacturer's website. Download the hotfixes for your device if your OEM both supports XP and 7."Everything we do is dictated by motive."

There are a number of things that could be going on. First and foremost, how old is the laptop and the battery. It it came with Windows XP in the last few years, chances approach certainty that the battery is of the Lithium-ion variety. Are you absolutely certain that Windows 7 is the cause? prior to installing Win7, how recently had you run it on battery for 3 hours? if you had not run it that long for some time, it is entirely possible that something in the battery happened to fail at abou the same time, and/or you noticed it at about the same time as installing Win7 I had a similar issue once, where shortly after installing a "Battery firmware" update on my MacBook Pro, I noticed that it was shutting down cold at about 80% battery life. Apple genius insisted it was a relatively normal failure for a battery that had more or less "Died of natural causes" I've since found out that if one cell in the battery pack goes bad, that is exactly what happens. When dealing with a Li-ion battery, the following rules of thumb apply: All battery chemistries break down over time. Your battery's total capacity (ergo runtime) will diminish over time. Deep cycling, (draining the battery to close to 0%) will accelerate the breakdown of the battery Therefore, to maintain the battery's chemistry, it is best to use it, but not to excess. On the other hand: your computer needs to monitor the battery. If the battery does not get a deep cycle to properly measure it's power curve, the computer must make assumptions that err on the side of assuming the battery has less capacity, and can reduce the runtime, not because the battery cannot provide power but because the computer THINKS it cannot provide enough power. to prevent that you generally need to give your battery a deep cycle, quarterly.
