X1000 doesn't power on
Just popping in

Hello all,
After years of service, my x1000 now won't power on or show signs of life. I have just replaced the psu, but that hasn't changed anything.

Does anyone have any idea what this might be or ways for me to check what the fault may be?

Pretty bummed as I was working on some new software for OS4.

Any help greatly appreciated.

Bummer!

Have you tried replacing the battery too? It seems like most
all of the NG systems are sensitive to the battery being up to
snuff.

Otherwise, I'd suggest hooking up a serial cable and watching the output if you can. If you're lucky, that will tell you where
it might be failing.

Let us know what you find!

Thanks,

PJS

I tried a new battery based on your suggestion but still nothing. It's as though I am not plugged in.
I have a serial cable on order but doubt the system has even come alive to start outputting anything. Almost like a fuse blew and is preventing anything from getting juice.
Are there LEDs on the mainboard that I should check? As far as I can see NOTHING is coming on - no fans, LEDs or anything.

There should be five bright red LEDs on the board, where three iirc are always on and the other two are used for the different checks.

If no LEDs are on whatsoever than there might be no power reaching the board.

You could try your old psu and see if this at least lights the LEDs.

In any way, remove everything and go from there, one piece after another back in place.

Could be anything, ram blown or not seated correctly, psu cable not completely plugged in.

I hope the old psu didn't blow a fuse

Obvious questions, so apologies in advance.
Did you try a different power lead? Check fuse in plug? Check any power strips? Try a different wall outlet?

Don't forget to check the clock battery status, i had once a dead battery on my X1000 and it also failed to power up until i changed the battery.

EDIT: already suggested on a previous post.

You have a multi meter tool?

Heard it many times on this thread, but just make sure the battery is giving a good voltage. Should be able to measure the voltage when it is plugged into to the socket too. Can just use a mounting screw for ground.

Make sure that there are also no shorts between the ground rail and 3v etc.

I am no expert, but dable in classic repairs from time to time and these simple things have helped me before.

If your PSU has a switch, try this:
Switch it off, and press several times on the tower power on button.
Switch on your PSU and wait some minutes. Then press the tower power on.

The thread is coming up with good suggestions...

Any chance bad weather mighta zapped something? It could be
your gfx card, for example. It happened to my XE.

Once you've confirmed the motherboard is getting power to it
(LEDs as mentioned), then I'd suggest pulling all the cards
and seeing if it makes any more booting motions.

If so, plug in one card at a time (start with the gfx card)
and see how things change.

Obviously, changing the PSU is an option.

Please let us know how things go.

GOOD LUCK!

This happened to me twice in the past 12 years. The 2nd time it was a bad CMOS battery and the first time I had do this technique below which ended up helping a few other users over at the Hyperion support site as well so hopefully it might work for you too;

-Turn off power to PSU.
-Remove plug from PSU.
-Remove power connector from the motherboard.
-Take out one RAM card leaving only one to the right of the PA6T CPU (i.e. 3rd slot from the left).
-While the RAM card is out check the slots 2 & 3 for dust build up (the CPU fan blows dust onto them) and use a small clean brush to remove it.
-Plug power connector back on to the motherboard.
-Connect PSU power & switch on PSU.
-Turn on X1000.
-If the X1000 boots up to Workbench, press and hold the power button for 3-5 seconds & it should shut off.

Thankyou for all of the suggestions.

I did everything mentioned in the thread and saw the fan on the CPU twirl for a few seconds and then nothing (which was more life than it had had since dying)

So I tried once more with the original psu (as previously suggested) and low and behold the x1000 came back to life!

So thanks again to everyone for all of your help. And as an added bonus because I thought the system was dead, I'm now in the middle of getting an x5000!

What are the power ratings between the old and new CPU?

When the serial cable arrives it will be interesting to see what it outputs.

Check section 8.3 LEDs in below manual for info on diagnostic board LEDs.
