Two possible causes come to mind.
1. Pram battery dead.
plug into charger for 24 hours
2. PMU confused.
reset procedure:
If the computer is on, turn it off.
Reset the power manager by simultaneously pressing and then releasing
Shift-Control-Option-Power on the keyboard. Do not press the fn
(Function) key while using this combination of keystrokes.
Wait 5 seconds.
Press the Power button to restart the computer.

I am not sure what is going on with my Powerbook. I have the 15"
Al 1.25 Ghz model and it keeps shutting itself down instead of
sleeping when I shut the lid completely to take break.
This is happening even on a full battery. When it is plugged
in, it will just go to sleep and wakes as soon as I open the lid.
I just had it happen again tonight - I was working on a Word
document (had it on battery power - 3/4 full) but had a phone call
so to preserve battery power, I closed the lid while on my call.
When I opened it to resume typing - Nothing, nada, zip. I could
not get it to wake up no matter what I tried (i.e. hitting space
bar, various keys, etc etc).
The only way I could get it to power on again was to plug it in and
then push the power key. However, even then, it took 5 tries
before it finally came on. Before that, I heard it come on but
then heard a click like the disk drive was trying to turn and then
nothing. I waited a couple of minutes and then tried again. Like
I said, after 5 tries with 2 minutes in between each, it finally
came on.
Any suggestions as to what may be going on ?
