My Beelink SEI12 Pro has been working for 2 years without any problems.
Recently, it started to randomly power down.
Once it powers down, I am unable to power it up with the power button, even
after holding it for a long while.
I purchased a replacement power adapter with the same output (19.0V/6.32A/120.08V) but it still powers down after a few minutes, usually after logging in to Windows 11.
If I disconnect the power adapter and HDMI cable from the Beelink SEI12 for a while (30 minutes or more), the whole startup/login/power down repeats again.
It is not usable at all any more.
What could be the problem?
