On my machine, an Asus C302C Chromebook, a T4 Torx driver was required. A T5 Torx driver was too large.

Good instructions and a worthy purpose to the site. Our devices should be more easily repaired. However, in my case the difficulty seems to be with the micro switch that the power button presses on. The micro switch and its circuit board look like they are replaceable. Does anyone know if repair parts are available for this device?
