Windows 7 Premium 32 bit

NO this in most cases is NOT a cause done by your computer, there are THOUSANDS of ppl having the same problem with their laptop AFTER installing. doing my research online I've seen some saying that after installing windows seven installing back to a different OS will not fix the problem windows does something to the battery life for some reason YES this is most likely a battery problem there aren't any cures as of now but I'm not too sure but 50 percent is a new one if you search the phrase "battery life becomes crappy after installing windows" and you will see alot of results well I didn't search that exact phrase but theres alot of that on google if you type the right words so basically ALOT of ppl are having this problem some say it's not windows' fault some say it's a BIOS setting problem we say Windows 7 either needs more fuel thats why it's draining battery like its its job OR it corrupts batteries whats the cause we may find out but a cure would be getting a laptop that already had windows 7. good luck mate

win 7 shutting down laptop at 50% battery

Ultimately, if you have Windows saying the battery is 50% charged and then all of the sudden dies, the problem is the system hardware somewhere misreporting the battery life (Windows 7 queries battery life slightly different than previous versions of Windows). Usually when this happens, people report that they do indeed have to plug the laptop back in to get it to boot reliably - if that is the case, then yes, the problem is that your BIOS or firmware needs to be updated to report battery life more accurately, or the battery itself does actually need replacing.

Windows along with any other system out there, only ever has readonly access to these batteries. Windows cannot "corrupt" as you put it these batteries. What do you mean by corrupt? Nor can Windows make the battery push out more electricity then it is designed for. Those special circuits I mentioned before prevent that from happening.

No, the problem is not Windows the problem is the hardware. If people stop all this foolishness and talked with there manufacture of there computer they will get the solution to there problem. Instead of this stupid witch hunt for a phantom problem in Windows.

my question is , Bettary's life is over ??? or may it be software related ??? !!
I have exactly the same fault with the same laptop. This morning it shut down at 78%. It is running XP so it is unlikely to be Windows 7 related. The next problem is trying to source a battery for this model. Checked lots of websites but no one appears to list this computer
