    Wonder it's just me or hardware/software issue.

    If I set brightness at 50% with power adaptor on, and sleep, unplug, open lid or do vice versa, the next time when the MBP wake up, the brightness either goes to lowest setting or highest, very annoying. Sometimes I see keyboard light did the same thing but not as frequent as screen backlit.

    Thanks for the great reply!

    I can see how I disable keyboard backlit.

    However, the screen brightness change is not ambient light related. It's under same light condition and it will change after wake up. The slide will not stick for some reason.

    Have you tried resetting the SMC and/or pram?
