SER5 not powering up

brann0

Hi,

I have a SER5 (S/N: A55603BF40294) since a 2+ years ago. Yesterday out of a sudden the PC (which was working until then) had no video output.

After powering it back on, there’s no video signal.

Things I have tested:

two different HDMI cables and a DP cable, on two different screens.
clearing CMOS, waiting for an hour then powering it back on
testing each RAM module separately
plugging a USB keyboard: they keyboard doesn’t turn on. This is concerning!

One thing I’ve observed: Power on button doesn’t seem to work. If I want to power off the PC after each test, I have to unplug it. And when I plug it back on the PC powers on without pressing the power button either. It feels as if the power button was constantly pressed, not allowing the PC to power on?

Let me know if you need more info. Thanks in advance!

New data:

after a day of inactivity (PC plugged off) I tested it again moments ago (only power, HDMI and keyboard) and the PC powered on normally. The moment I plugged the ethernet cable, video went out.

I tested that ethernet cable in a different PC and it wasn’t working correctly. So I’m getting a new ethernet cable.

In the meanwhile, the PC isn’t powering on so I’ll clear CMOS and wait for a day.

Hello there,

Sorry for the trouble.

Could you please send us a picture of SN code(two lines) at the bottom of machine ?

May I ask if you unplugged the power cord and HDMI cable when trying to clear CMOS?

Here are some potential solutions:

①Please change another power supply.

②Please check if the fan spins?

③Please tell us if the Keyboard light is on ?

There’s the requested information.

Also, I unplugged everything when I cleared CMOS.

I’m not able to try with a different power supply at the moment, will let you know if I can borrow one.

When the computer fails to boot, fans are spinning but USB keyboard doesn’t light up.

I’m a bit busy but I’ll try to test the PC again later today, will come back with the result.
