powerbook freeze on wake - solution?

Message #1 - Posted 2005/03/27 - Giles

For all those having occasional freezes on waking from sleep, particularly 12" powerbooks after the 10.3.8 update.

I think I might have identified the cause. Changing from battery to power supply, or vice versa, while the powerbook is asleep, is enough to trigger the freeze on wake. It doesn't happen every time, but frequently enough. Nothing else seems to produce the freeze repeatably.

I've tried resetting the PMU, with no change.

This is a bit annoying but it does mean the problem is avoidable. I haven't had any freezes when waking the powerbook in the same power state as putting it to sleep.

Interesting. I have a similar machine, but was unable to bring on a freeze with that recipe.

What fraction of wakes don't?

Do you have any USB device that you may have disconnected at the same time as the power?

It didn't seem to be universal when raised here before, but if I remember, Roger and Flavio had encountered the freezes as well, also with Rev A 12" 'books.

What fraction of wakes don't?

I've not counted, but it is noticeable. At a guesstimate, one in six or so, with the changed power supply condition

Nope, it is freestanding. The only usb connection is a camera, but that rarely and never when asleep.

All I can say is that, so far, I have not had a freeze when not changing power supply, and I can reproduce the freeze - if not every time - when changing supply. This may, of course, just be a glitch in my 'book (12" Rev A 867).

Yep. Of course, that's gone now (replaced by house contents insurance after a fall); haven't had that issue with the new one.

That is about right. I hadn't noticed the changed power situation..

Thanks. I'll do a few more tests and report back if I can bring on a freeze.

Yikes. Look at the time!

Morning, if you are up yet.

Personally I wouldn't worry if I wasn't seeing it :-)

As I said, it wasn't universal, but a fair few of us with Rev A 12" 867 'books were getting the same thing. Since Flavio's upgraded, I suppose it is just me and possibly Roger left with the problem.

I know, I know. It's compulsive, like driving an old car at exactly the revs that bring on big end rattle, just to prove it is still there.

Mine's the late 2003 1Ghz.

Well let us know if you hit the red line, but unitl then, sleep easy.

On my 17" Powerbook 10.3.8 actually fixed the problem, rather than caused it.

I used to get the freeze, now I do but after a couple of seconds of black screen the desktop restores.

well i probably was if it was after 4am, at least in body if not mind....

my powerbook occatinly is a bit hetisant about waking, but has only froze 2 times from wake, at 10.3.8 once just after installing, and once the other day though i had upset it,

but what does happen just now and then is it doesn't wake, or it flickers into life rather than being there, genurally if it doesn't wake closing then opening does the trick, i wait a mo til i hear the harddrive park then reopen.

OK, just me left then. So, I have a solution for my problem, given that Flavio doesn't need it any more. Sorry to anyone else who got needlessly excited.

Nope, tried all that. The power switch thing is the only repeatable one. Flavio had something similar, and having had a browse through Apple discussions, we are not alone.

Still, avoidable now.

Um *looks around nevoiusly* i do that all the time, the battery nowadays will often just let go so it goes to sleep on battery, i go get power cord, and carry on. this happens most days to be honest.

If it ain't a problem, it ain't a problem. Plug in without worries.
