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.

definitely sounds like a hardware issue on the laptop. is it still under warranty? – Keltari Jan 19 '13 at 16:25
Could you boot into a Linux live CD and see whether the problem occurs there also? Does windows report the battery as fully charged? Have you checked the windows events logs? – terdon Jan 19 '13 at 16:38

It is either the hardware or battery that is causing the problem. Possibly the loose connection problem at the junction where the battery is supplying power to the laptop.

It is most likely a hardware error in something else than the battery because the problem persists after a battery change.

I would like you to try the computer with Linux so that you can rule out a software error, also this might make it easier to see if it for example always dies at a specific charge percentage.
