So I bought a new battery for my laptop and installed it. I booted into Linux (gentoo) and kpowersave recognized the new battery and for the next few hours showed it charging up. The guy at the battery store said I should charge it fully and then discharge fully to calibrate, so, once full, i disconnected AC power and continued to work. kpowersave recognize that power had been removed and showed the battery discharging at a normal rate. After about 1 minute, my laptop just shut off. No warnings or attempts to suspend or hibernate or anything. Power was just cut off. I tested several times and always got the same result. I assumed it was a bad battery, but then I had to boot into windows for something and decided to try it there. In windows, I waited till the charge was at 100% then disconnected AC and let it run. It ran for about two hours as expected before dying. But if I boot back into linux, it dies again after just a minute or two. I don't even know where to begin. Any ideas? $170 battery that I can't take back because it does actually work, and anyway, it seems to be a software issue.
