G5 desktop - made a "ding" & went dead

I have a G5 desktop computer, powerpc model, running OS 10.5.8
I was using my computer when it suddenly made a pronounced “ding” and went dead. I mean dead; not even the momentary winding down of the hard drive I would hear with a sudden power loss. I removed and re-installed the battery to no effect. I was going to try resetting the PMU, but I couldn’t locate it; the only diagram I had was for a G4 computer.
I don’t have detailed information for which model of G5 I have.
However, when I opened the side panel, I got the following at the bottom:
2GH DP/PCI X/GB 400/160 GB/SD/R9600/56K
I have limited access to a computer (this Windows pc).

That G5 is probably toast,

In reply to: G5 desktop - made a "ding" & went dead

based on the following:
The G5 series logic boards were constructed using capacitors which had an inherited fault, they were C*rp. Google will tell you the full story but all computer manufactures around that time period used defective capacitors without knowing that they were defective at contstruction.

take a look at your mother board and look for capacitors that have bulging and/or leaking tops.

only cure for this is the complete replacement of all the capacitors on the logic board, not an easy task as Apple used lead free solder to attach them in the first place

You noted a battery.

Given the age did you try a new one? I do run into folk that won't risk a 2 dollar test part yet will pay the counter 100+ for them to deliver the bad news. I'm confused over that.

Anyhow my esteemed Apple colleague is spot on about those bad caps. The only good news is if it's that, you usually can see them if you inspect them (google bad caps for pictures and stories.)
