Urgent- Powerbook has gone completely crazy

Okay, so I came back from lab earlier today when I took my laptop out of my bag to find that the machine would not turn on. Baffled by this, I plugged it into a power outlet using my AC adaptor, and sure enough it worked! Except my computer was acting as if it had no memory of system settings, and when I logged in it had the clock set to the default Unix 0-time all macs arrive thinking is correct. I soon discovered that the computer would not run off the battery at all, and when I next turned it on it had every bit of amnesia. And now I notice that even a lot of my programs have lost their settings (though I reset the NVRAM as an attempt to brute-force the issue if it could be solved in so simple a manner, so that may have caused it). Has anyone encountered this sort of thing before and had it not be a hardware issue that they had to send it to Apple for? Well, I'll take whatever advice I can get from you guys.

It seams like both your regular battery and you pram battery are dead, but there could be many more reasons for this. But thats my first guess.

My computer continues to claim that my regular battery is 93% charged... I don't see why it would die so soon either. Then again, the PRAM battery being dead would be even worse. ><
