iBook wake from sleep problem

Message #1 - Posted 2004/02/01 - Ian Gregory

I have a problem on wake from sleep with iBook running 10.3.2 Never saw it before 10.3.2 and have not seen it yet when I put machine to sleep myself, only when the power manager does it.

When I press the power button to wake from sleep things seem OK in that I get the dialog asking for my password, but then there is about a 1 in 5 chance of getting a black screen. This is NOT a problem with the backlight because I can still see and move the cursor on the otherwise black screen. The Only way out I found is to hold down the power key till machine shuts down.

So I turned on sshd and the next time it happened I got in using Putty from my friend's Windows machine (oh the shame!). Everything seemed to be working but how to regain control? After a bit of mucking about this process caught my eye:

/System/Library/CoreServices/loginwindow.app/Contents/Mac

I decided to try killing it and my iBook screen came to life with a login window. Ok, so I had to log in again but that is much better than having to power-cycle.

Can anyone point me in the right direction. I am not quite ready to give up and disable power management.

Many thanks,

I have had similar problems. Sometimes I can break out of it by closing the case, waiting til the pulsing light tells me it has gone to sleep, then opening the case again and re-entering the password. Next time I plan to try an unconditional kill of the front process by using cmd-option-shift-esc as soon as I have entered my password. --
