I have a Mac Mini G4 1.5GHz running MacOS 10.4.11.
A few days ago, two problems started:
1. The machine would not go to sleep. Neither pressing power button,
nor selecting Sleep in Apple menu, nor using keyboard power button
(dialogue box appears, but selecting Sleep does nothing. The machine
can be shut down or restarted.
2. The machine did not recognize its external drive, which is
connected via FireWire.
Tried booting into single user mode, while booting up shows message:
FWOHCI Error trying to clear PHY ports.
then
FireWire(OHCI) AppleID 31 built-in now active, GUID 001124ff
fed33758; max speeds 100.
Apple System Profiler shows FireWire Bus, but connected device does not show.
Ran TechToolPro and the FireWire test could not be run. It was greyed
out, and the information panel that appears when pressing the "i"
button says "FireWire Not Available."
Any suggestions appreciated. Also is there a connection between the
sleep issue and the FireWire issue?
Thanks.
