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
