AC adapter ring activates to amber instead of green on TiBook Hg.
I have a 500 MHz TiBook G4. It has been dormant for at least one year. I suspect the PRAM battery's dead.
I plug in an iBook G4 adapter (65W) and immediately get an amber ring instead of a green ring. The battery fails to charge. The TiBook fails to power up and chime.
I want to confirm this is a condition that can be remedied by unplugging the (likely) dead PRAM battery.
