Macintosh OS/wake


QUESTION: My iMac (10.6) is set to wake at 5.30 am, which it has been doing just fine for years. Lately I've noticed that it wakes at 5.05am, then goes to sleep, then awakes at 5.30am. I've checked the energy saver sleep schedule and it shows 5.30am, as I have set it, for sleep. Is there anything I can do to fix this problem? I've tried looking for RAM settings but I don't know where to find it.

ANSWER: I am not sure.
Set it to not wake or sleep, restart, reset SMC and PRAM, set it to wake as wanted.

QUESTION: If I reset PRAM and /or SMC, can I expect most everything to look the same, except that I'll have to adjust the volume and wake settings? I just wanna be sure that when I do this, the computer doesn't turn into something I don't recognize. Thanks.

There will be no easily recognized differences.
It will set things to out of the box conditions.

An administrator account can change system settings that are active in all user accounts.
These system settings are typically preference lists (plist)- files that are read at boot up.
Some of these settings are stored in persistant memory maintained by a battery that sometimes needs replacing (PRAM).

Power related settings can be controlled by the System Management Controller (SMC) on your Mac. If you are experiencing issues with powering on your computer, sleep, wake, charging your Mac notebook battery, or other power-related symptoms, you might need to reset the SMC instead.
