Product: Z400
Operating System: Linux

Hi community friends,

 

My Z400 (6 memory slot, centos 7.8) turns on by itself and off after few seconds, then repeat on and off till I unplug. This happens again one or two days after I plug in. I checked all connections; internal power cables, HDDs, DVD, video card, memories, and infiniband host adapter, and replaced battery on the MB, but the issue was not solved. Wake-on by LAN is not enabled.

1) Can the failure of one of devices (including memory) turn on computer? Or power supply?

2) Is there any good way to diagnose this issue? Because this happens spontaneously and I reproduce this on purpose, checking each device one-by-one is not practical.

 

I appreciate any suggestions.
