Hello good people,

i have an XPS 8910 from 2015. It worked fine until last night. It powered off by itself, like someone cut off the power. There was no power failure.

 

i have been trying the solutions on this forum. Tried the PSU test. The green light comes on and is steady. Fans run at full speed.

Noticed the PSU’s fan does not run though. I remember reading somewhere this is normal.

here are the steps i’ve attempted:

1. Removed power cable, pressed power button for 30 seconds, reconnected power and tried to power on. At first no cigar. Tried again. Powered on for less than a minute and died.

2. Disconnected all connected devices, external and internal, except for the processor. Reconnected 1 by 1 and tested PSU Green light. No problem there.

3. After everything was reconnected, tested PSU’s green light again, it lit up and fans run.

4. Cleaned internally, removed all the dust. Just in case. No cigar.

i’m at a loss. I’m thinking its the motherboard. But is it possible to test the motherboard?

thank you.
