Wake-from-Sleep issues: More confirmation for disconnecting all peripherals before sleep

We recently published a special report on dealing with a broad range of wake-from-sleep issues associated with incremental Mac OS X updates or other triggers.

One workaround covered in the report was the disconnection/removal of all external devices must be disconnected before putting the machine to sleep.

We continue to receive reports from readers having success with this procedure.

"I've had wake from sleep issues with my 17" 1.33 GHz Powerbook, and I couldn't solve the problem, despite the helpful advice from your readers. My symptoms are pretty typical - after closing the lid, I see the front light come on and off, but when I open the lid, the computer seems 'awake,' but I get a black screen that cannot wake unless I reboot.

"I've solved the problem! I have a Firewire 400 expansion card plugged into my PCMIA slot (it gives me 3 ports). Its a card made by PC CE (?), and when it is unplugged before going to sleep, the machine does wake from sleep. If it is left plugged in when I close the lid, I can't wake from sleep. I'm so glad I finally solved this problem!"
