Hi there.

i start having a problem with my MacbookPro April 2008 since update of Leopard to version 10.5.6.
now it suddenly goes to sleep, and it happens very regularly.
maybe 2-3 times within 2 hours.
it happens with AC attached and during running on battery.
so after it goes to sleep. it can be Woken up after 5-8 seconds later by pressing any button.
and it really pain in one place to have this problem while loving Mac so much.
if there is any solution, may be to do downgrade to 10.5.5, because as far as i remember it wasn't doing such problem before. only now :(

hope to hear from you soon.

thanks.
 
I think you' d better go to the Exposé preferences. Then, check the "Active screen corner". The problem should be there.

I've tried all what macOSx experts told me, but unfortunately it didn't work.
the problem still exist.

so i've done reset of time and something else while boot holding ALT+CMD+P+R button combination, pressed POWER butoon for 5 seconds while battery was disconnected.
Removed the Power saving System preferences from the Library folder, so when it restarted it was all as with default settings.
i also put NEVER go to sleep neither with Poweradapter nor with battery connected.
but now, i'm really annoyed that this problem still exist.
because i travel and do presentation with my mac, so if it goes to sleep while work - it wouldn't look well.
now, i'm a bit concerned, whether upgrade to Snow leopard would help.
thanks in advance
