Why won't my mbp boot or charge the battery?

Metin:

I have reviewed many of the questions about non-booting mbps and don't think I yet have the answer.

I have tried the smc reset, and the safe boot, and the single user startup, removing the ram chips one at a time and both at the same time (got the tone every second with the fans spinning) and still no luck.  I press the power button briefly and just get a flash of the sleep sensor light, or hold it down steadily and get the sound of the optical drive trying to spin (there's a disc stuck inside--the mac osx startup disc) and the sleep sensor light flickers out and it poops out after about 3 seconds.

I am able to try to boot off the battery (charged on another mbp) or the ac adapter, but cannot charge the battery in this one--the light on the magsafe connector is either dim or bright steady green, never amber.

Although I have a hunch the problem is related to the infamous nvidia gpu, as I am unable to get it to boot, the apple genius test cannot be performed to determine if it qualifies for a free LB replacement.

One day it was operating, and the next day it would not boot.  Although there were problems with an intermittent black screen, it would always come back, before that fateful day.

----->>>>I am wondering if the failure to charge the battery is a dead-bang indication of a LB failure, merely requiring its replacement, or is it a dead-bang indication, as far as apple goes, that it is not part of the gpu extended warranty?

Although I cannot remember the names of all the troubleshooting steps I tried, none of them worked.  I have also reviewed the apple service guide and troubleshooting steps (at Scribd).

I have yet to open it up and try to disconnect everything possible to test the LB alone.  I am building up my courage to do that, and check the hd at the same time.

I have not yet tried the apple 800 number to plead my case.  That appears to be the last chance before the $310 depot repair.

I can tell there are more knowledgeable and experienced hands on deck here.  If anyone can help solve my dilemma, I would appreciate your help.
