Wake up promlem with Jaguar & MacG4?

Message #1 - Posted 2007/11/18 - Salmon Egg

Only sometimes, my G4 running Jaguar10.5.1 (and original) does not wake up properly. I am using a USB Apple keyboard with a Macally mouse plugged into the keyboard.

When I press a key, the mouse lights up but I have no control from the keyboard or the mouse. The screen remains dark. The pilot light in the power button does not vary in intensity as it does during normal sleep.

The caps lock key does not light up when pressed.

If I unplug the mouse from the keyboard or unplug the keyboard and replug, the mouse light does not turn on.

There is power on the USB cable that I use because I can light up USB powered speakers. That power is not available during normal sleep.

If I press the power button long enough to turn off the computer and reboot, everything seems to be OK.

I conclude that there is something going on in Leopard that keeps USB devices from being serviced correctly. What can that be? How can that be corrected?

Jaguar or Leopard? What kind of G4?

This is a corrected (I hope) and supplemented repeat of a previous post. I apologize for what seems my growing ineptitude.

I had the same problem just before posting this supplement. I confirmed that the pilot lamp was brightening and dimming on about a five second cycle while computer was asleep. I pressed the caps lock key once. The pilot light steadied. The mouse lit up brightly and then went to its standby intensity. I heard the fan in the computer start up again. It was deja vu all over again. There was no control from the keyboard and the screen was dark.

Have you ever replaced the 3.6V Lithium PRAM battery? I've cured a sleep issue by replacing it previously (I also own a G4 which was still running the original battery).

That said, I also have had /occasional/ wake from sleep issues.

Cheers,
Andy.

I have not done so. Ichecked the cell voltage about a year ago and it seemed to be OK. It will be easy to do so again and replace it as well.

Your suggestion brings up another question. How would a bad cell give such trouble? During sleep, the pilot lamp is getting power and cyling in intensity. During sleep, is not the power supply providing power that the cell would apply when the computer is off?

I just had the problem again. After shutting down the computer using the ON button, I measured the PRAM cell in place. It was 3.67V. The nominal value is listed as 3.6V. Unless something happens during startup that draws significant current from this cell, it should be doing its job of keeping the PRAM going. It is true that it is the original cell and it may be as much as four years old. In any event, I will zap the PRAM whether needed or not.

Hmmm...I'm out of my depth on that one. All I know is that the sleep issue I had - which involved a brand new hard drive not spinning back up and completely locking up the machine forcing a hard reboot, was fixed instantly upon replacing the little green PRAM battery.

There's all sorts of stuff relating to 'power management' that I can't adequately detail, all I know is that it's a fairly cheap and easy thing to try.

Cheers,
Andy.

I just had the same problem again after the PRAM zapping.

I replaced the PRAM cell because black magic might work. If it solves my problem, I will have to understand why. It would be most disconcerting and lead to superstition with regard to computer behavior. If there is no black magic, the problem should show up again.
