Press power button multiple times to on
Hi, i have a macbook pro 13” Late 2011, to on the power button has to be pressed multiple times. If pressed once only, the Macbook will switch on without chime and display
I have tried SMC and NVRAM reset, disconnecting the keyboard and switching the macbook on with the pins on the motherboard, the same thing happens
Does anyone have any idea how to fix this problem?
