Recently I've noticed that my beloved X31 will occasionally (as in once or twice a month) refuse to boot. I push the button to turn it on, but the unit does not indicate it is receiving any power. This happens whether I am trying to boot from battery power or from AC adapter. To fix the problem, I have to take out and put back in the battery (original IBM, holds a good charge).
Another aspect to this problem is last week I put the laptop to sleep, but when I came home I discovered that the battery had completely drained... which is odd, because the battery was about 25-50% full and was sleeping for maybe an hour.
When I use my laptop, I usually have it plugged in to the AC adapter. And when I shut down, I will leave the screen/lid open so that the unit can cool down more quickly.
I've read that doing the "residual discharge" trick may help. Is this a battery issue, or is disaster looming?
Thanks in advance
