This used to happen to me, but I don't remember exactly what I did to fix it.

Try resetting the PRAM by holding down these four keys at startup - "apple", "option", "P", and "R".

OR

If that does not work you may want to try resetting the PMU (power manager unit).
1) Turn of the computer

2) Reset the power manager by simultaneously pressing and then releasing Shift-Control-Option-power on the keyboard. Do not press the fn (Function) key while using this combination of keystrokes.

3) Wait 5 seconds.

4) Turn the computer back on.


Good luck.
