Public bug reported:
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. I have tried
the latest versions of Ubuntu and Debian. 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 Ubuntu 20.04.1 (kernel 5.4.0-42-generic) using the Grub
bootloader with active Secure Boot (fully supported), and then I turn the
notebook off or restart it in Ubuntu, 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 Ubuntu again. I have tried install recommend drivers
and software..
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.
