unable to power off, and bios screen wake up again! at NUC5i3.

k.um · 06-13-2023, 03:13 AM

I have dualboot of UEFI with Slackware and Windows10 in Slackware64-14.2.
And I updated Intel Visual Bios. I see, pc didn't power off even if I execute '/sbin/poweroff'. In updating, I might mistake.
In shutdown of Windows10, it powered off. In Slackware(also Built-in UEFI Shell) it didn't power off and bios screen waked up again.
In /etc/rc.d/rc.0, it didn't change even if instead of "/sbin/poweroff", "/sbin/halt -p".

Thanks for many Help!

Code:

shutdown now -h

This Problem is resolved.

The cause is USB port that USB cable's length is 5m and Camera at an USB cable. If this USB cable is disconnected, I could power off the PC at "/sbin/poweroff".
This cause is a high load for PC, but I don't understand why PC is not powered off.

But I finish this question.

Thanks for yours.
