Any ideas about this sleep issue would be greatly appreciated.

I am hoping that someone can help me with my powerbook G4 problem.

i can restart the computer, but when it gets to the login screen, it immediately goes to sleep. i can manage to wake the computer up, but it only lasts for about 2 seconds and then it goes back to sleep. and it just keeps on staying that way. i’ve tried resetting my powerbook a few times, but the result is the same when it goes back on.

i am having difficulties logging onto my powerbook, because of this “sleep malfunction”. i can’t use my computer, and my life is on this computer!

please, someone help.

“If you have a Macintosh computer with an infrared (IR) receiver, you can put your computer to sleep using an Apple Remote. Press and hold the Play/Pause button on the remote until the computer goes to sleep. When your computer is in sleep, pressing any button on the remote will wake the computer… ”

I can imagine creative ways in which this could go bad.

I’ve been having a lot of trouble with this issue of not waking from sleep (G4 15″ alum 1.67, running 10.3.9). Sometimes I think it is related to a battery level status issue but that is just a hunch. I too have adopted the practice when switching to battery use of unplugging the AC adaptor before putting the computer to sleep. That seems to reduce the number of times this happens but is not 100% effective in getting rid of it.

In my model of Powerbook, they apparently introduced something they call “safe sleep”, which caches various things to the hard drive before sleeping. It sounds plausible that an almost full hard drive (does anyone have one that isn’t) would cause trouble for the safety of the sleep. But obviously the problem is more general than just this model of machine or newer. Probably safe to bet that there are numerous ways to trigger this behavior.

Useful tip for keyboard failure when the machine is awake.

Ok but what about when your machine is powered off? I have been having this problem on and off again for a couple years. SOmetimes the crazy thing will go to sleep and somehow lock the keyboard as well. REcently, the powerbutton locks as well. Seemed to re-set itself last time when I put in a disk… THis time that isn’t working.

I had read somewhere that there was a key combination that can shutdown and lock all buttons, but why is this happening sporadically when the computer puts itself to sleep?

wath can i doo?

I have the same problem!

Funny thing is, it just happened a minute ago whilst the computer was _awake_. I did not hit num lock, and it was not asleep.

When it happens when it’s asleep, I try to click on all the cancel/try again etc buttons on the log-in panel, and hit various non-letter keys until it works again. Or, hard restart.

Such is life.

I will report my issue the now to el Apple.

Will get back if they provide a solution.

This, at least, seems like the problem that BBee is having. A bit late, thus probably unhelpful. But there’s my two cents.

There is a workaround that I have used 100 % successfully - hit the shift key, then the caps lock key on then off again. then the shift key again, all in rapid succession.

Yes, I know that sounds silly. But it works everytime for me, and has mitigated the need for reboots to get my keyboard back.

Hope this helps,

I can’t log in, not one of the cypher/letter keys is working.Trackpad works fine, as do brightness sound etc on top, gues the F row works but functions keys are useless in the login window… pram resets, safe boot restarts, deleting caches (startup via apple t, so the laptop acts like firewire desk) nothing works. apple care = unfamiliair with the problem, although more reports on the net. It isn’t hardware, since a ‘open firmware’ restart made it possible to type some commands in the unix window (to no avail btw), so the keyboard hardware is okay.

is there a hidden keyboard lock/unlock chord? any advise welcome…

What you are reporting is strange because I feel my problem started when I upgraded from 10.4 to 10.4.1.

The upgrade from 10.4.2 to 10.4.3 fixed the problem for me!

As a matter of interest, did you upgrade from 10.4.0 to 10.4.1 to 10.4.2 to 10.4.3 or did you do an upgrade from 10.4.0 to 10.4.3?

I am using a 12″ PB 1.5 Ghz and experience the same problem posted earlier — when I put my PB to sleep by shutting the lid, the keyboard fails when I wake the computer by opening the lid. This is a serious problem since I can’t enter my password and therefore am locked out of my system. This problem appeared after downloading 10.4.3, but I don’t know if they are directly related.

Has anyone tried contacting apple?

try upgrading to 10.4.3 - I can’t reproduce the issue since the upgrade - I think it might have resolved it (fingers crossed!)

You know, I think you’re right. I believe that my PowerBook may have been doing this.
