Im sure this has been answered a million times but Im not finding a good solution while sifting through the newgroup archives.
Here's my question.
I have a Powerbook G3/300 Lombard.
I put it to Sleep. It sleeps.
I then try to wake it my touching the mousepad or enter key. Nothing.
I then touch one of the keys on the keyboard and the computer powers down, then rings out it's Mac chime (the same noise that occurs when you start up a Mac).
I then try to restart it by hitting the Power key. Nothing.
I then do a Apple+Ctrl+Power, and the thing starts up.
The PRAM looks fine. The rechargeable battery is fine. The RAM is fine and checked. The only thing I've done to it is install an upgrade Bluechip G4/500 CPU in place of the old. I never owned it before the upgrade, so Im not sure if had problems beforehand, but I was doubting that would be the problem, since the new CPU runs fine.
What gives? Thanks! sean

You have a fault in the power circuitry. The PowerBook tries to come out of sleep mode when you press a key, then suddenly decides that the battery is dead.
It's just possible that you have a faulty battery, so check that first, but I think you're going to need some components replaced.

Oh. Then all bets are off: that's precisely the sort of thing that would cause your problems. Do you have the original components ? If so, replace them and see if your problem goes away.
