回答先: How to: replace power buttonI followed this procedure and had some success. Some points: I used Loctite GO2 Gel adhesive with no trouble. I completely disasembled my switch to solder the wires. There is a hex screw in the back which adjusts the space between the contacts. I found it was quite critical in its adjustment. A bit like tuning a carburettor! If it is too tight or too loose the switch will not function correctly.
