Hi all, I've been having a problem with my macbook for the past few months now. when i turn it off (by pressing the power button or by going to apple>shut down) the computer will start the shut down procedure and the screen will turn off. BUT the computer isn't really off. I can hear it humming and when i close the screen, the sleep light will pulsate like normal.

I have let the computer sit with a black screen for 10+ minutes before closing the screen with the same effect.

the only way i can get the computer to actually turn off is by holding the power button for about 5 seconds.

I tried resetting the PRAM? i think, and it helped for a day, but the problem occured again as normal. So, what can i do? im getting tired of having to hold the button every time i want to shut the computer off. TIA

Reset the SMC (System Management Controller). What model MacBook do you have?
