Antwort auf „How to test topcase/power button?”i know this is old, but: that second comment (wiggle it around) that stupid and while yes it will work it could also casue further damage. all mac's have a little 'jumper starter' point on their logic board - like the ibooks method. the great thing about the macbooks logic board is the two tiny pins you need to connect (with a small flathead) has a tiny ON/OFF sign, like the actual power button. it's usually near the fan on most boards. get your glasses out , or even magnifying glass and you'll find it. also image search 'macbook jumpstart'
