    I have a mac book pro and Ive been having some problems...

    1 is that when the backlight is low, it makes a loud humming sound, can this be fixed?

    2 my laptop has started to just randomly shut off when not connected to a power supply. Theres not warning about battery life, it just goes black and shuts off and will not start up until I plug it into the power supply...:confused:

    The humming sound can't be fixed with resetting the smc...you should go to the apple service, there is something damaged (normally). the problem is common.
