Hey all, I saw some threads where it is recommended to calib the battery if the person is using the laptop from the AC power for the most of the time. Which I did yesterday. Plugged in for 2 hours. (with full charge) Let the computer do some heavy works. the computer automatically shut down. I had to go for work, so I left the computer the way it was for 9 hours. Came back, and plugged in the charge before I went to sleep. Right now, I have coconut battery open, and it tells me: Current Battery Capacity: 5051mAh (92%) Original Battery Capacity: 5450mAh It used to hit 5505mAh (100%) before calib. Did I do something wrong or is this normal?
