Lenovo M93P Tiny restarts after Lenovo logo

[Gripen]

Hello. I have several Lenovo M93P tiny that have the same problem. When turned on, the Lenovo logo appears and then restarts. It reappears, restarts again and it goes round and round to infinity. I can't enter the bios either.

I tried to replace both CPU and RAM but it didn't help.
What could be the problem?

Bios version/revision not supporting the CPU maybe?

Everything worked. Windows has been installed. When it was received by the customer, it no longer worked and Lenovo has been restarting ever since.

Did you supply the power adapter or did the customer use their own.

The customer use their own, but we test another supply and universal power supply. The supply works with another Tiny.

i have a broken m92 board, i shorted the body of the clock generator with a diy southbridge heatsink. its now a spares board. you probably have a corrupted bios by the sounds of it. just reflash the bios chip and try again.

I also found a bios on this forum and a vinafix site. I tried both but it only got worse. Power LED not lights, no sound, no display but fan always spin. I flashed back the original bios.

Have you checked all the ports for any damage.See if the lan chip is getting hot

check lenovo support. sometimes thay have iso to download and burn, put cd in drive and it will recover bios for you.

it might not be available for every model but it is for most of them.
google a bit on how to start recovery.. sometimes its a jumper, other times to hold a button on keyboard while turnin on pc

There is a jumper on the motherboard, but no CD reader. Does it also work with a USB CD reader?I can only try it tomorrow.

i think it oly works from sata optical device but it does not hurt to try

also, post your bios backup, i might be able to fix it (no promises do)

I tried with USB ODD, 4 Tiny was fixed.
