Hi,
My PowerBook had a battery problem (dead battery which did not charge anymore). It lost date and time several times while mac was on AC and power cord was removed. Now it has a brand new battery.
Since then, Powerbook does not go to sleep mode anymore:
- if it goes to sleep following settings of energy saver prefs, it doesn't wake up anymore, black screen and LED stays on
- if I force it to sleep through the Apple menu, it freezes with a black screen with the following white text: You Mac needs to be restarted by pressing for a few seconds on the power button.

I have tried to reboot with apple-alt-P-R and waited 5 reboot
I have tried sudo pmset -a hibernatemode 0 in the terminal

Nothing changed...
Any (good) idea out there???

Thanks

PMU reset, PRAM battery OK

Yes, PMU was resetted. I've checked the PRAM battery which is still alive, giving about 3.7V
