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
 
Yeah if the on/off button on the pc case is faulty
Jumping the pins on the motherboard should turn
The pc on

Only thoughts would be
You're possibly jumping the wrong pins
They're small and usually down in the corner
Where it's hard to see properly what you're doing

Or the problem actually is the pins /or pcb traces from the pins
That would be a new one for me
Never seen that before unless someone actually snapped a pin

Could test the on/off button with a battery and an led
Probably test the pins too if got any of those little connectors
In a drawer or on an old pc case or something you could use
By doing same thing using a battery and a led
 
Do you have a reset switch? You could use that as a power switch

"I've tried shorting out the pins where the power button cable attaches to the mobo but nothing happens."

That doesn't sound good.

Not a bad idea to use reset
But that's only going to work if they've been
Jumping/shorting the wrong 2 pins
Since if Jumping the correct pins doesn't work it's not
The on/off button that's the issue
 
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
 
Last thing comes to mind
How old is the cmos battery?
It seems unlikely to be the problem
But it's cheap and usually easy to replace
If asus haven't hidden it under heatsinks or something else
That's hard to remove
 
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 :D 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. :D
 
Glad it was something simple

Not difficult thing to accidentally do
The pins are small and usually down in the right hand corner
Your hand obstructs your view as well while you're
Trying to put the connectors on the pins

I much prefer motherboards that give you a little plug
You can put the wires on
Then put that on the pins all in one go
Such a cheap little thing that makes life a lot easier
Should come with all motherboards really

Oh oh you've started the upgrade itch now :cry:
 
...started the itch ?? It's never stopped :D

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

Rather than I need it?

Even though i don't really need it :cry:

Yup that :cry: 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
