Question Pwr_sw doesn't work, shorting Super I/O pins does, what to do?

[rat_boy_11]

Hii❤️
I have an Asus H97 plus motherboard and recently it unfortunately died. Well, almost. Shorting the power button or reset pins does nothing, but after poking around i noticed that shorting top left pins on the Super I/O chip turns the PC on, and the pc afterwards is working quite stable. After shorting said pins the pwr_sw pins work perfectly fine until the psu is unplugged and plugged in again. The bios does not save settings enen though the cmos battery is new.
Tried several working PSUs and CPUs with this system.
What should i do? Did the motherboard die completely?

CPU: i5 4590 / i5 4460
CPU cooler: Stock Intel cooler
Motherboard: Asus H97 plus
Ram: 1x 4gb ddr3 1600
SSD/HDD: None
GPU: None
PSU: Several 500W noname PSUs
Chassis: None
OS: Windows 10

you say the pins are working fine if you short them? edit- I am not sure I am clear on what you are saying about which pins

Does the case have a reset switch you can swap over? Or contact case manufacturer about a new switch...or an aftermarket switch.

I picked this up for a similar situation and for testing purposes:

You have a short on your motherboard(or more specifically an electrical failure)...eventually your motherboard will need replacing.

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.

Sorry if i wasn't completely clear, english is not my first language. I am shorting the pwr_sw pins with a screwdriver, which does nothing untill i short the super i/o chip's pins. The system doesn't have a case right now.

Thank you. I suspected that shorting might be an issue, and if that's true.. Welp, that's sad. I have several noname PSUs that i tested with my other PCs, none of them resolved the issue on this system. Both i5 4590 and 4460 behave the same, same with all the DDR3 i have. No storage is connected to the system, no usb port is being used.

The bios does not save settings enen though the cmos battery is new.

Have you measured the voltage of the new CMOS battery (CR2032) with a multimeter and confirmed it's good (around 3.0V). You might have another dead battery.

I had a motherboard where the spring contact in the CR2032 battery holder (for the positive terminal) was bent out of shape. There was no electrical connection between the side of the battery and the motheboard.

With no backup power to the BIOS chip and Real Time Clock, I was unable to save any settings.

Check the spring contacts in the battery socket and make sure they're both making good contact with the CR2032.

It's probably a different fault, but worth checking.

How did you manage to find that shorting pins that (so far as I am aware) are not there to short, and it worked?

Pure coincidence. When i couldn't turn on the PC for a first few times i just started poking around with a screwdriver and, well, found the pins. Not the most scientific or safe method, and i probably damaged something in the process
