BIOS vs nVidia chip on HP laptop

Specs: Windows 7 Ultimate, 1.5/2Gb
My laptop, HP Pavillion 2625la w/Win7, was kept as an emergency backup system. It was treated with kid gloves so much that it was stored in an airtight case etc. The system had a whopping 1.2 hours of up time. Now:

1. when plugged in, with battery present or not, it powers on and will not shutdown until its unplugged and the battery taken out. Even when holding down the power switch or closing the lid it simply restarts to a black screen with white lettering.

2. on the blackscreen about halfway down, after checking RAM etc. I get two warnings/errors:


0271: check date and time settings


0251: System CMOS checksum bad - Default config used

Press F1 to resume

3. I can then press any button on the board and nothing happens so getting into any setup screens is a non-starter

4. During all this time I'm getting 1 long and 2 short beeps (there is no exact beep/blink code for this model although others point to a video card/chip problem MAYBE) and the little lighting bolt LED is blinking on and off, also the LED just above the touchpad is blinking blue and orange.

5. I'm unable to only charge the battery b/c who wants to listen to that beeping for an hour, however it WILL charge.

I understand the problem with Nvidia vs HP video chips but this just doesn't seem to be a vid problem. I've done all of the resets (hard and soft), pulled/cleaned/reseated all memory and drives etc, to no avail. All fans and drives are working (rather they make noise) and there doesn't seem to be any overheating anywhere. As far as I can tell the POST doesn't get far enough to boot from anything else so thats out. It acts like a power problem, maybe in the BIOS? If it is that freakin vid chip then I'm hosed b/c obviously the warantee is gone. Can I do some kind of emergency flash the BIOS to ensure that it's OK? If its a vid chip problem then why all the power symptoms?

For starters, you need to replace the CMOS battery.
