I have a strange hardware issue:
Out of a small suite of 8 computers, 3 have just stopped playing ball and won't POST.
if you plug the power cable in to one of the three desktops, they automatically come on, the CPU and PSU fans spin up and the optical drives LED comes on briefly as do the power and hard disk LEDs. In fact they flash in some sort of pattern.
I've tried disconnecting all the drives and USB ports etc. to see if a faulty component is causing the issue bunt it still does the same thing.
Unfortunately I didnt have time to take any hardware out of a working computer and swap it with one of the non-working ones and I wont be back on that site for a couple of weeks so I'll give that a go when I'm back there.
I've just uploaded a video of it to YouTube so you can see the LEDs going beserk!
I think I just disposed of half a dozen of those
It's the power supplies at fault as I took one from a working one and it powers on OK with that one.
No luck in finding a power supply via Google so they're now out of action
We had some of these a few years ago that had this issue, basically you have to do the following to recover it:
1. Unplug power
2. Press and hold the power for 15 seconds
3. Release power button
4. Replace power
PC should now power up, hope this helps.
What's the model number of the PSU on these?
