After closing the lid and then opening again my system does not appear to wake up. Sometimes I hear something happening when I click a few keys but no screen output. I have to shut down and reboot. This time I had the mail client running but nothing else. This is after installing the new O/S.

Reset your PRAM by holding the ALT+CMD+P+R keys while turning on the Mac.


To reset your SMC you just pull out all cable's of the mac, keep it like that for 2 minutes.
