Powerbook freezes after wakeup

Message #1 - Posted 2006/04/28 - Vinayak Naik

Hi,

I have 15 inch PPC powerbook (1.5GHz). After getting it's logic board replaced, I am seeing problems when the computer wakes up from sleep.

Some times after wake up, the screen becomes white and the computer freezes. The only solution is to reboot the computer.

I have reset the PRAM and NVRAM. After that the frequency of problem has reduced, but still it hasn't gone away completely.

Any idea what's wrong?

Thanks,

- Vinayak

I recalibrated my battery, removed YDL, and reinstalled Tiger. After that the screen never froze but still the computer hang once. I uninstalled Camino. After that the computer didn't hang.
