I was uploading to Zipcloud for the first time as a backup. Evidently powercord got disconnected and battery life died causing the laptop to turn off. Now can't get PowerBook to turn on. The cord has the green light lite showing that power is getting there but absolutely nothing happens when pushing the power button
PowerBook G4 (17-inch 1.67 GHz), Mac OS X (10.5.8)
If the battery wasn't already on its last legs, it may be capable of retaining
a charge and perhaps boot the computer again. Once batteries go flat or
empty of power, they can be damaged; especially old marginal ones...
So, you may need to get a replacement battery, check the power adapter,
and then check the DC-in Board (System Profiler, power) to see if the
PowerBook G4 is getting any power once you can get it to start up again.
The information there should include battery life, charge cycles, reserves
and if there is a limit to what one may expect. A full-charge on a worn out
battery may say "100%" while it may only retain under 80% capacity.

You may have found (or will find?) the PRAM battery on the logic board is
without power, too; so it would need to be replaced; as this may affect
booting a PPC portable or desktop model with such a battery once dead.

Troubleshooting may require you to have known-good working spare parts
on-hand such as power adapter, battery. Another Mac with FireWire cable
could let you get into the HDD and get an archive copy your files saved to
another device or drive; by use of FireWire Target Disk Mode:

Hopefully this helps somewhat.
Good luck & happy computing! 🙂
