Hi there,

I fear my PegII G4 may be dead. I'd welcome a detailed step-by-step procedure to find the faulty part.

The symptoms :
At startup, both leds will stay on. Drives will init, but no OF.

Whet I've tried :
Changing my R8500 for a Voodoo4 and a R7000/PCI
Taking out one memory module, then the other
Reseating the CPU board
Taking out the battery, then putting it back
Disconnecting all drives
Taking out all PCI cards

This leads me to think that either the CPU board or the motherboard passed away. Any Ideas?
Best Regards.

Hi Sergio,

Sounds like the g4. I would closely inspect the heat sink, the fan either stopped spinning or it physically came off the processor.

I would do that, than contact BBRV to see if they have any ideas to help.

Kind regards,

Matt

The fan works. I checked the heatsink, it is held in place by two peg-plus-spring thingies. When pulling it, I can see thermal paste. And there is almost no dust in the sink.
There are some big capacitors on the board as well. I wonder how I can test them - I can use a soldering iron so if they are the problem I can try replacing them myself.

I tried getting the serial output through a nullmodem cable, and got only one char of line noise each reboot...
How can I be sure it's the CPU board that's faulty?

That really sounds like the CPU-board isnt working.
I have read about other people having the EXACT same problem and then it was the CPU.

This seams to happen more often to the G4 pegs then the G3.

:-x

Grr..

My Pegs having real troubles, sometimes it doesn't power on, some times it does, then it crashes in either MorphOS 2.2/Amiga OS4.1 or Linux, then won't power on.

And sometimes it works perfectly all night then won't boot in the morning, grr...

Sometimes I get weird errors, on all OS, I've changed the Ram, the PSU, the Hard drive, removed everything put it back, and still the same, it's the intermittantness of its that the problem. Doin' me head in!

So it's probably the CPU module?

Anyone fix them? or got a cheap G3 module I could buy/borrow?

In my case it was the MoBo that was faulty.
Try testing your CPU against another MoBo and your MoBo against another CPU.

And how do you do that with only one Pegasos, he asked innocently...

Try contacting the manufacturers directly:

(Edit: And then get back here to report the end result of course! )

Progress is being made...

I shall report back!

Have you check the power supply, Ive had in past where power supply not delivering voltage high enough anymore. that can cause odd quirks.

I've tried 3 different PSUs...
