Hi,

Is there any differences on 2010 era power buttons vs 1998? I have Asus P2B-VM and installed it into my old 2010 or something Fractal Design Define R2, but it wont turn on with the power button. I removed the power button from the 1998 case and with it it turns on. Both power buttons have the standard 2-pin connector. I also tested the 2010 case power button with x570 Taichi on my other pc and it works fine.

A momentary contact switch can only fail if it has too much resistance, or infinite resistance. If you see zero ohms when measuring with a voltmeter with the switch depressed (circuit closed) then it should work. Do you see a difference in the resistance reading between the two switches with a voltmeter? Using a screwdriver to power on ATX boards when they are out of the case is commonly done.
