Dead PowerBook G4

[Will Cheyney]

I have an original titanium 500Mhz PowerBook G4 which wont startup
I used it faultlessly last week, but when I tried to turn it on today I ran into problems.

Any idea what this may be? I've tried holding down the reset switch on the back, a different battery and power adaptor.

Motherboard battery's go bad on older tiBooks. Replace it and put in a superdrive/combo drive new harddrive at the same time because they have to take the case apart to get to it. It is above the optical drive, glued to the topcase.
