Power Button not working - Any suggestions

Pooh · 31 May 2025 at 11:06

Hi All

Strange behaviour with my TRX-40E motherboard. All of a sudden the "power on" switch has stopped working. I can get the PC to start by pressing the onboard power button on the bottom right of the Mobo but nothing when I press the power switch on top of the PC. I've tried shorting out the pins where the power button cable attaches to the mobo but nothing happens.

Any clues ? If it was a dodgy switch then I would have thought that jumping the power pins on the mobo would have fired it up.

Not seen this before

Thanks

Thanks

I hadn't thought of trying the reset switch - good idea

I'll give it a shot later

re shorting the pins, it was the two that the PWR connector was on that I shorted, so don't have high hopes. Might be the mobo is starting to show its age

The CMOS battery is relatively new, changed it about a year or 18 months or so. It's a pig to change on the TRX40. ASUS made it about as difficult as you can make it to a) find it and b) get access and replace

Update...

Dug out the mobo manual and checked pins.... Bugger

I was a pin row higher on speaker pins rather than the power pins. God knows when I did that.

Any how power connector put on the proper pins and all seems good.

Mcnumptie called it, cheers matey.

Sometime you just got to go back to basics.

Guess that's the beauty of this forum, great to get another perspective, thanks guys, much appreciated.

On the down side though, I found a TR3970 & Mobo & water cooling combo on eBay that I had my eye on as a replacement.
Can't really justify it now though.

...started the itch ?? It's never stopped

Just bought another 128GB of RAM then a 5090 and now a block for the 5090.

Need to get some of my old gear into the MM

yeah you really need 256GB to load up notepad and play solitaire.

Yup that

and also I've seen RAM usage go up to over 180GB when tracking in the Fusion page of Davinci Resolve Studio. It loves RAM
