iMac slow to wake from sleep after SMC reset

[RavenSword]

So I unplugged my iMac and did a SMC reset to try and fix a long standing graphics issue I've been having but now I notice after I have unplugged the computer from the outlet and plugged it back in that it docent wake from sleep as fast as it used to. It shows a blank screen for a few seconds then shows my log in screen. this is only a issue if the computer has been asleep overnight. Ive tried everything: another SMC reset, a PRAM reset, and I even reinstalled Mac OS and did a clean install. now I'm worried I somehow damage my iMac from simply unplugging it, which I know is impossible. Anyone have any ideas? I even did a diagnostics check and everything came back fine.

How old is your Mac? Can you still call Applecare? Might be time to call in the pros!
