Power button no longer works. How to fix

[george2005]

Nothing happened after I press the power button. No any noise, no fan spin. Any idea how to find the problem?


MB: ASUS Z170-A
CASE: CORSAIR CARBIDE 400C Compact Mid-Tower Case
POWER: SEASONIC SSR-550RM

first, after making sure the cord is seated properly in the wall and in the PSU at the back of your computer case and the PSU's rocker switch is set to the "ON" position, you might eliminating that it's not the computer case's power button - on your motherboard, you have a power on button, ref #17 -

remove a case cover, and push it - if computer starts, then it's simply a matter of replacing your case's power button

Call Corsair with your case model and order a replacement power switch module

Are you sure the computer is plugged in/your power supply is turned on? Have you checked that that your power button connection didn't come loose for whatever reason?

forgot, check that your lead from the power button on the computer's case is making a good connection - pull the small connector highlited in the below schematic and push it back on a couple of times

if system doesn't turn on after all this, then it's probably the PSU - there are tutorials on youtube on how to check your PSU
