12" Powerbook problems

[Tyler Schmidt]

So far I have only had this problem happen to me twice in the 6 months
I've owned my powerbook, I have know idea what goes wrong but my
powerbook didn't wake from sleep mode...I know the computer is running
because i can hear it and it gets warm but nothing shows on the screen!
I push the power button and nothing happens...after pushing the
button several times ( not knowing wheter its on or off) and closeing
the computer for about 20 mins it boots up fine. Anyone else have this
problem?

Give the contrast keys a couple of taps to make sure that it has not for
some reason dimmed the screen. This happened with my Lombard and the pre-jag
10.2 version of the OS. Only happened a couple of times but responded.

Yep. It's happened to me three times in the past week. I don't know
why. On one occasion I had to reset the power management unit to fix
it (see the Apple web site for details of how to do it).

It's very annoying - the whole reason sleep is useful is because I'm in
the middle of something and don't want to have to save and shutdown, so
this behaviour is very irritating!

Something similar has happened to me two or three times, but I got it to
shut down by holding the power key down for about 5 seconds--perhaps a
little longer--and then restarting. The last time this happened, I ran
DiskWarrior 3 (a purchase I've been repeatedly thankful for), and it
found some major problems with the drive.

Interestingly, I did that about a week ago, and the machine refused to
start at all from the hard drive (either partition). DW3 found major
corruption. 2nd time it found such--though I don't recall if the
problems were the same ones.

One annoying thing: I've found that if I put the machine to sleep and
then disconnect things (external mouse, monitor, Ethernet), the machine
not infrequently wakes up, sometimes with that annoying blank screen
problem.

I thought I read somewhere that the Mac was waking up, saying "Oh look,
the external monitor is gone, I'd better take note of that for later" and
then going right back to sleep.
