Does anyone have a solution to the lid-close death on Aluminium Powerbooks?

I'm using 2.6.8-rc1 on a 1.25GHz Alubook (Nov '03). When on battery power, 3 minutes after the lid is closed the machine just stops. No shutdown, no panic (that I can see), it just turns off...

The problem is only evident when on battery power and has been present since at least 2.6.3-benh2 and possibly all 2.6.0

Not that I think it makes any difference but I've disabled all the pbbuttonsd (0.6.1) settings that might trigger a sleep. I'm pretty sure this must be at some level lower than pbbuttonsd.

Has anyone else got this problem or know anything more about it?
I don't need the machine to sleep, I just need it to stop dying when I've closed the lid!

Apple: PowerBook G4 Battery Recall

maybe this explains it a bit???

No, not really, I had several powerbooks Aluminium now (exchanged due to display problems) with several different batteries... Now I'm on a different(higher) serial number and it exposes the same problem. I think it is related to the fact that sleep simply isn't supported at all for those machines until someone (ATI) comes up with a 'real' driver for the graphics card.

Have fun*

I have the same problem.

Strange thing is it doesn't shutdown after closing the lid if the power is connected.

Another issue is it's impossible (correct me if someone has a workaround) to have the screen off when the lid is closed (with power connected). And I believe having lid closed while screen is lit is bad for heat (heat). This means if laptop on, have to leave open.

No, actually the backlight does turn off when the lid is closed (whether on battery or AC power).

erm, can't post my configs right now. Hmm...it's about time I updated the configs on my site (see sig).

And no, my battery isn't subject to the recall. So that definitely isn't the problem.

I have this problem too! My laptop powers down exactly 4 minutes after closing the lid when pbbuttonsd is running and only when on battery power. Could this be related to OS X upgrading the PMU firmware?

I have the following:

Code:
$ grep Cover /etc/pbbuttonsd.conf
onAC_CoverAction      = blankscreen
onBattery_CoverAction = blankscreen


and have no problems.. this may also depend on your framebuffer settings / I'm not sure here.

Code:
$grep fb /etc/pbbuttonsd.conf
dev_FrameBuffer       = "/dev/fb0"


If you're having trouble what do these lines say?

-Q

I have app-laptop/pbbuttonsd-0.7.2

I have the same problem on my iBook G4 1,33 GHz (mid 2005).

As far as I read this turn off is done by the PMU to avoid overheating or something like that. OS X is possible to circumvent this somehow, but so far there does not seem to be a solution to trigger this in Linux. So we have to keep the lid open. Any better news are welcome.

Maybe similar, maybe not...

I have a Powerbook G3 Firewire (Pismo) which will do this after being idle for a little while. The lid doesn't need to be closed, indeed, closing the lid does the whole suspend-to-RAM act.

The screen goes dark, just like it should (as I've set it up), then a few minutes later the whole thing just turns off.

From what I can tell the same script is being called for lid close as is for the timer action (which I'm assuming is what is triggering this new, unwanted off mode.)

I was reading about this new quantum computer that is able to work even while it's off. Well, the Pismo doesn't do this. I'll be tracking this thread with interest, hoping what fixes your guys problem works for me too.

Humm, I still remember something about OS X updating the PMU firmware. It must be some sort of feature that only OS X knows how to use. I'm sure not all Apple laptops do this, because it seems that most people don't have any such problem, or if they did, there would be a huge number of complaints about it? This is why I think it is only causes by a certain firmware from a certain version of OS X.

About the problem, it turns off exactly 4 minutes after having the lid closed and only when the power cord is disconnected. It doesn't make sense that that it is to protect from overheating, because it doesn't do it when the power is plugged in even with the lid closed!

I would be interested in finding out how to access and change NVRAM, the boot ROM, and the PMU firmware! This information might not be freely available because of viruses?

I have a Powerbook G4 1.67Ghz, and I have the same problem. I remember reading somewhere that older iBooks did not have this issue, but like you said, the newer PMU causes it. It even happens under OSX. I purchased a program called Sleepless, IIRC, and it had a feature that was supposed to prevent the laptop from sleeping on the lid close, for wardriving and the like. But like you said, after 4 minutes, the laptop just died. I have yet to find a solution to this issue.

Just thinking, it seems to be some sort of feature to prevent a crashed system that never went to sleep from draining the battery. Did you say that it OSX will always put the system to sleep whenever the lid is closed and on battery power? If so there probobly isn't an easy to fix this if osx does it too.

Maybe there is some heartbeat feature to the PMU that can keep it from shutting down?

It's done by the PMU. Unless you can reverse engineer it, you're stuck with the fact that it will shut the machine down 4 minutes after closing the lid.

So even under OSX, the system will not run on battery power with the lid closed?
