Need help with Sleep issues

[mbze430]

I was wondering if anyone can point me to the right direction on getting the Sleep feature to work properly?

Right now, when I put the Laptop to sleep. I get a black screen (backlight is still on). But it freezes and never wakes up again.

I have the Energy saving to turn off screen in 5mins. Which only blacks out the screen (backlight still on). And 30mins goes to sleep. I can wake up the screen before 30mins. But once it pass the 30mins mark, it freeze.

I tried use SleepEnabler.kext but that didn't help. I tried the darkwake=0 in Chameleon and that didn't help either.

Please Advice

This is an HP/Compaq C62 running ML (10.8.1)

You have to extract your DSDT and apply appropriate edits to it. It also sounds like you have nullcpumanagement kernel extension loaded.

What you are having is graphics suppression. To get proper sleep, you need to delete nullcpu, remove sleepenabler and dsdt patch HPET, RTC, TIMR and LPC.
