Have a G4 Powerbook with OS 9.2.2. Has recently refused to stay asleep
longer than 1-2 seconds when using the menu command. Need suggestions
for resetting or troubleshooting.
Thanks, JB

Do you have any external devices connected, especially to a USB port?
Changes in state of USB will wake up a sleeping computer, and one of
your peripherals might be triggering a wakeup.

Other than that, a hardware problem or power management unit issue seems
most likely. You might need to reset the PMU.

For detailed instructions on how to do that, we'll need to know exactly
which PowerBook G4 you have.

Thanks for your reply. Did disconnect all external devices (connection
with DSL modem). The model is a 2002 Titanium Powerbook with 800 MHz
microprocessor. Thanks in advance for farther help.
