System shutting down without warning

[plrbear12]

I have an HP DV7t-3300. The system randomly shuts down - no BSOD, no warning - and will not turn back on. I have to unplug it, remove the battery and hold the power button a bit.

If I boot the machine without the battery, it runs for hours/days with no issues.

Could this be just a bad battery? or is it, as I suspect, an issue with the motherboard charging system?

If the issue is not present when the battery is removed, I'd be inclined to say it's the battery itself which is causing it.
