TiPB won't wake from "sleep"

Message #1 - Posted 2002/01/02 - Andrew Duncan

This happened to me five times this weekend, sometimes right after rebooting (X.1.1). I close the case, the icon light goes out, but the flashing sleep light never comes on. On reopening, the screen is blank, but machine won't wake up. Hitting the power button doesn't restart, so it's not actually shut down. But I can't wake it up except by forcing a restart with ctrl-cmd-power.

The only thing I can see correlated is that in each case the USB hub was connected. I've had other USB weirdness. In this zombie state, the hub indicates that it's still getting power from the computer, confirming that the computer is not really sleeping.

This is very serious -- rebooting several times a day is unacceptable...

Your supposition may be correct. I've had similar problems recently, getting my Mac to wake from sleep. (Fairly) recently I added more memory (not a likely suspect) and a PCI card that gives my machine two USB ports. (I have a beige desktop G3, I think the last model Apple supplied without USB ports.)

Just as you describe, now when I put the machine into sleep mode I can't get any response except by forcing a restart. Is it the
USB ports? Maybe someone in the know will respond.

Very interesting. Just for the record, my other USB symptoms are:

* Printer doesn't respond
* Zip disk inserted but doesn't mount

In both cases, unplugging and replugging the USB connector from the machine gets things working again. Hmm.
