Wake from sleep help in 10.1 System
Prior to the release of 10.1, my G4 with an Adaptec card would not sleep at all. It was greyed out in both the Energy Saver and the Apple menu. With 10.1, though, it's now possible (although this is still not the 'deep' sleep of a non-Adaptec machine).

Sometimes though, especially if the machine has been sleeping a long time (overnight), when I return and try moving the mouse or hitting the keyboard to wake the machine up, nothing happens. The first time this happened, I thouhgt I'd crashed so I went and pressed the power button on the front of the machine. I didn't hold it in long enough, though, so I was about to press it again when I saw the screen come back to life.

So if you have an apparently dead sleeping machine, try touching (briefly) the power button and see if it awakens your machine. This has worked for me every time I've used it, and it also worked on a friend's G4 (also with an Adaptec card). It seems that sleep mode puts our USB keyboards and mice so far into sleep that they aren't even listening for activity. The power button, though, gets the machine's attention.

This fix may not work for everyone who's having wake from sleep issues, but it's at least worth a try.

Low USB Power after wake up?
Authored by: sublinear on Oct 21, '01 07:56:50PM

I have a problem that if my machine is asleep (also sometimes overnight) when I come back my keyboard and mouse no longer respond (the mouse is plugged into one of the USB ports on the keyboard, and the keyboard plugged into a 4 port USB hub which is full).
There's an alert message on screen saying there isn't enough power to power the device (but the alert doesn't actually mention ~which~ device). I have to reset my box...

I wonder if this tip (mentioned in the article above) will help? I guess I'll find out in the morning ;) I never had these problems with OS 9.x...

I understand that the Deep Sleep issue of the original post is now solved with the Power Mac G4 Firmware Update 4.2.8 (North American). A number of people say that this firmware upgrade has solved the deep sleep issue with Adaptec cards, maybe it will solve your pwer problem too.

FWIW, I have same effect in both OSes (G4 AGP with Adaptec 2906 SCSI card installed). My workaround has been unplug and replug keyboard, all comes back to life. I'll try the power key.
