Thanks for replying. Yes I have tried 3 different graphics cards. The problem is not there. I think the problem lies in the mother board. After 1 sec. closes the board itself for the power.
Have a nice Day

Recently my X1000 refused to boot also with some strange serial output, different from time to time, with reboot or halt at board init, with sometimes error indicating that no VGA valid board were found, and sometimes nothing att all. I suspected my GFX card and replace it with the old one without any luck. I replaced the battery and same result. With all the test, the PSU was like KO, no power on. I suspected it to became too weak or damaged because I remarked that one of the GFX fan was slower that the others before it stopped working. I went to my local commputing store to bought a new one, and the technician offered me to look at the machine to check it up.
My PSU was OK finally, It tells me that he unmounted all parts and checked and cleaned all the connectics. He reassembled all parts again, and tada, it booted again with all the original parts!
It is now working again.
Regards,

If you haven't already I would do a strip test. Strip down to bare minimum. That is disconnect all drives and all cards. Don't even try with any graphics card. And remove any input devices on USB and anything else plugged in externally. Caveman style, just the board in the case plugged into PSU. So only RAM remains. Turn it on and see if the LEDs light up as normal.
If not, switch it all off, then remove the RAM. Turn on again. Without a serial setup you can't tell what the machine is thinking or even if it is thinking. But that is usually a last resort.
A long shot, tried the recovery firmware?
Finally, according to your other thread, you replaced the CPU recently. I wonder if the new one has some conflict. Or some incompatibility to the X1000 power setup. Have you tried testing with your other PSU? This may be easier than stripping it down to test.
Edit: See you had trouble with your other CPU. Something obviously failed. Hopefully the PSU didn't do any damage to the board. Some early boards had a power problem where an IC would bust. Did you have a fixed board? Later ones fixed the issue.
I optioned on the serial port when I bought mine. It's just a simple backplate with serial port that plugs inside onto the serial header. Common PC ones have ten pins but X1000 is only three pins so you may need the official plate. They are still listed here:musa wrote: ↑Wed Aug 18, 2021 10:52 am Hi Hypex
Thank you very much for the answer.
I do not have serial port in my X1000
I have tried to disconnect all connections except the power supply.
(graphics, network cards, hard drives, ram, and floppy drives).
I have tried with a new power supply and I have tried again with the old one.
I have changed the coin battery.
I have not tried to recovery the firmware.
When I turn on the power there are light in diodes 1 and 2 for 1 second and then power is off .
Then I can not turn on the power for very long time.
