Package: kernel
Version: 4.19.0-10-amd64

Hello. I’m using Lenovo ThinkPad X390 Yoga (model type: 20NN002NMC). I
have been using dual boot of the preinstalled Windows 10 x64 and Linux
(formerly Debian based distro. I have tried the latest versions of
Debian and Ubuntu). About 6 weeks ago, after updating the BIOS to
N2LET76W 1.75 (https://download.lenovo.com/pccbbs/mobiles/n2lur14w.txt)
and the Intel Management Engine Firmware (12.0.67.1579), an issue arose.
When I boot to Debian 10 Buster (kernel 4.19.0-10-amd64) using the Grub
bootloader with active Secure Boot (fully supported), and then I turn
the notebook off or restart it in Debian, it won’t turn back on – it
won’t POST, the screen is black, etc. After that time, I need to unplug
the notebook from the power adapter, or remove it from the dock, and it
will boot on battery. But it won’t boot while plugged in until it boots
into Windows and is turned off/restart from it. After booting to
Windows, it works fine while plugged in, until it is turned off in
Debian again. I have tried install firmware-linux-nonfree etc...
It looks like a BIOS/Firmware error related to power management. I’m
using the latest BIOS/Firmware updated via the official Lenovo software
– Lenovo Vantage (bios version 1.76). Notebook was sent to Lenovo for
repairs, the motherboard was replaced, yet the problem persists – hence
thinking it’s BIOS/Firmware related.
Lenovo claims it’s Linux’s issue, even though the list it as officially
supported (https://support.lenovo.com/sk/en/solutions/pd031426) and
there refer me to the community. Lenovo stuff inform me too, that this
issue may be related to requirements Windows 10 v2004.
Many thanks for your help.

I am using Debian 10 Buster, kernel version 4.19.0-10-amd64

Hi

This bug was filed for a very old kernel or the bug is old itself
without resolution.

If you can reproduce it with

- the current version in unstable/testing
- the latest kernel from backports

please reopen the bug, see https://www.debian.org/Bugs/server-control
for details.

Regards,
Salvatore
