    820-3115 power button only works with smc bypass

    the system boots up fine in smc bypass. in normal mode it doesn't boot up unless the power button is held for 5 to 7 seconds

    My first bet would be a defective SMC.

    But before that, check SMC_ONOFF_L what is happening when you press the key. It might also be just a bad keyboard.

    Any corrosion?
