HP Pavilion DM3 / Windows 7 My laptop suddenly goes black without warning, restart and it goes to "Start Windows Normally."
Does not occur when plugged in to AC.
I got a new battery and had similar, if not more frequent events, after a few days.
Could be hardware related to the discharge circuitry or possibly both batteries drift down and suddenly kill the machine.
Any thoughts re: cause or ways to evaluate the problem. The crash is so sudden, it is unlikely an identifiable log even is generated.
