I have a Compaq Presario R3000. This is only a year and a half old. MobileMeter has the battery wear at 0%. Speedfan and MobileMeter both have the temps at high 30'sC low 40'sC under light load. The problem is that when on battery sometimes (about half the time), I will go from almost fully charged, to my computer just shutting off. It doesn't go into stand by or hibernate. It just shuts off. Could this be something on my mobo shorting out and draining the battery dry????
