Asus ET2232I Not Powering On

I have an Asus LITEON WN6607AH-AD all in one PC. It is different from the one that I had to choose in the picture to the right, since IFixIt only had an option for something similar. I received it from a neighbor, and it doesn’t power on. I’ve managed to take it apart and do some diagnostics. I’ve tried pretty much everything I could think of, but it won’t boot. I think it might have something to do with a fried motherboard, which is a ET2232I Rev 1.2 board. I’ve looked online for replacement board, but it would be very expensive ($100+). If y’all have any ideas on what it could be or if you’ve had this problem before, then I would greatly appreciate your response. I’ve attached 2 pictures of the motherboard in case that would help.

Here is a list of the things I tried:

  • Installing a ram stick (already has internal memory)
  • Removing unnecessary cables from the motherboard
  • Removed CMOS battery
  • Tried 2 power cables

You don't mention what diagnostics you tried.

Have you checked the power supply, for example? Is it outputting 19VDC?

Sorry. I have 2 different power supplies and I know for a fact they both work fine. I forgot to mention that the computer on the side I had to choose is different from the one I'm working on. IFixIt didn't have an option for my model. I'll try to add more info.

Still can't get it to do anything...

crwdns2934271:0crwdnd2934271:0crwdne2934271:0

So it is completely dead?

No lights,

no fans spinning,

hard drive does not spin,

no beep codes sounding,

BIOS can not be loaded,

etc.?

It shows no signs of power. Not even a light.

1. TLDR ASUS All-In-One was not booting - just black screen.

Possible Fix - New CMOS CR 2032 battery at horrific location.

2. Background

ASUS All-In-One PC Model: ET2321I

Booting was flaky for several months. Would

halt in BIOS scrolling info, and need function keys

pressed to finish booting.

After 3 weeks of power off it failed to boot.

The screen powered on after power cord was plugged in,

but boot button failed - screen stayed dark after

many permutations of button press:

1. Short press

2. 40 second press

3. Short and long presses with power cord out, then plugged in.

3. Testing power

Ohmmeter detected about 19V DC - good.

Ohmmeter on power button (after case removed) showed 3V DC

before press, and 0V after press - seems OK.

4. Case and motherboard cover removed.

A. Two screws under CDROM. Use paper clip to open

Plastic in CDROM hard to detach - broke small plastic

piece on second detaching.
