What to do when Macbook Pro will not come out of sleep mode?
One method is to restart. Hold the power button until the machine turns off. Then press the power again to turn back on.
Intel-based Macs: Resetting the System Management Controller (SMC)
That was the first thing I tried. No response by the computer; it stayed in sleep mode. I suspect the cmos battery may be expired.
The computer is a G4, not intel based.
I'll ask the moderators to move your question to the proper forum.
