Reset the SMC:
1. Shut down the computer.
2. Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
3. On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
4. Release all the keys and the power button at the same time.
5. Press the power button to turn on the computer.
I have the same problem and used your suggestion to press shift-control-option and power on. After that I pressed again power on and have now an error indication:
The sleep light blinks three times and beeps with each blink.
I found out, it assumes there is no memory. What can I do, to convince it, that there is memory?
