Crash when wake from sleep..help!

Question

I've had this problem on and off, but it's become very serious ever since I installed the latest security update.
Pretty much every time I open the PB from sleep it crashes...what I mean by that is that the screen is black and there's no response from the computer.
I have tried:
-Repairing permissions
-Trashing the power management preferences
-Swapping the Ram (I have 2 512MB RAM sticks)
-Running various hardware tests
I don't know what to do anymore, but I'm getting very very frustrated!
Specs are Alu PB 1.25GHz, 1 Gig RAM, 5400 rpm HD.
I'm hopeful someone here can give me some help!
Thanks!

Answer 1

I had the same problem with an Al 15" 1.25hz powerbook. My problem seemed to be related to waking after I had put it to sleep by closing the lid. Among many other experiments the advice below seems to have solved the problem. I now put the book to sleep with the power button and 's' and it no longer opens when you lift the lid, but that is a very small inconvenience.

Hi Mightdancer --
Yes, there is a way to turn off the function whereby the PB wakes when the lid is opened. I learned this just a few weeks back, reading a post by Ned Snowing of this fora. I've found Ned to be one of the more reliable and authoritative posters on here, and here's what he wrote, in pertinent part, on the subject of how to stop your PB from waking up when automatically when the lid opens:
You can ... tell your PowerBook to not wake when you open the lid. In this mode you need to either hit the space bar or power button to wake the computer. This is what I do as I don't always want to wake my PowerBook on the moment I open the lid.
To do this open Terminal and type :
pmset -g
This will give you your current power settings and if you look down and check next to "lidwake" it will either be a "0" or "1". A "0" means that it will not wake when you open the lid and a "1" means that it will wake.
To set the "lidwake" mode to not wake type the following :
sudo pmset -a lidwake 0
… and subsequently type in your administrator password when asked. By typing "pmset -g" again you should see that the "lidwake" entry has been modified and your PowerBook will no longer wake when you open the lid.
Obviously if you want to restart your PowerBook's behaviour to wake when you open the lid type into Terminal:
sudo pmset -a lidwake 1
