T23 pulsing fan

[JBUK]

I bought a couple of spares/repair T23s last week. One had the pulsing fan and no POST problem.

I stripped out the mobo expecting to find loose inductors. They were fine. I tested the screen on another T23 and it was fine, so not too bad a deal then as I have a useable screen.

However I came back to it later as something was nagging me about it. What I discovered was that the CPU had been installed the wrong way round. A new hole had been created on the socket to allow this. I refitted the CPU correctly and it booted up quite normally.

So we now have something else to look for, CPU related problems, as a cause of a non booting pulsing T23.

I can't imagine why someone would spend the time to create the extra hole for the CPU, when it won't work with it in like that.

Very interesting...

Gee, wouldn't it have been easier just to clip off the superfluous lead on the CPU???
