Today is the day that I calibrate my battery (!) and I currently at the stage where my laptop is fully charged (green light) and I am using it while still plugged in for "two hours or more." After this, do I just unplug it and leave it running/use it until it approaches 0%? Will it put itself to sleep when it gets low? Also, am I allowed to put it to sleep at anytime during the calibration process on my own or will that disrupt it? I got this information from this thread.
