Right. So my laptop likes to randomly just turn off while it's unplugged and running just on battery power. It's a 12-cell battery and was functioning just fine until a few months ago when this problem arose. Normally I would just dismiss this as a bad battery but the charge shown in both Windows and on the LED display on the battery itself show a decent amount of charge every time. If the computer dies like this it cannot be restarted until it has cooled all the way down and recharged at least a little. Otherwise it just attempts to boot up but immediately dies before getting to the splash screen.
Edit: I've noticed the shutoff seems to occur more frequently when the computer is doing something more strenuous like opening new programs, installing things, etc.
Also when the power cord is plugged in instead of just dying I get a black screen (as in the screen's off, not just blank). The sound light is white and the wireless light is orange and the NUM lock light is also on. From here all I can do is hold the power button down until it powers off.
When I have the cord plugged in and no battery I don't even get to the HP splash screen. I just get a black screen, the same light configuration as above but the NUM and CAPS lock lights blink twice to indicate a BIOS corruption failure.
Anyone have any ideas? I'm pretty much tapped.
Things I've tried:
-removing the battery and cord and holding down the power button to flush out excess power or whatever
-taking the CMOS battery out and then putting it back in again
-using different power cords
Any input would be extremely helpful. Thanks in advance.
