MBP thinks it's charging but it's not
I found my MBP shut down this morning. I tried turning it on, but only got the dead battery symbol on the display. I plugged in the charger and the green light lit up. Pressed the power button, and got the dead battery symbol with a lighting bolt underneath. Left it to charge for a while. When I came back the symbol was still a red empty battery with bolt. The charger was stone cold.
I took the MBP to the store. They plugged in their charger and we got the exact same result. Green light on the charger. Not amber.
So it seems the charging system is fried and I need a new computer.
Is it possible to bypass the charge circuit and hook up my bench power supply to the battery, fooling the MBP into thinking the battery is full? Is there a fuse for the battery that I can check? I just need to power up the MBP long enough to retrieve my data.

I'm feeling a little more hopeful now.

I got a call back from the store who did some additional diagnostics, and pulled the machine apart. Apparently the battery is swelling up, two sensors have failed, and there are some other issues with the mainboard. He did say he was able to make it boot up though. I'm going to pick it up tomorrow.
