Greetings.
It seems my assumptions were misplaced. It seems the ACPI event is
connected to the accelerometer perhaps, since it fired also when tilting
the laptop rather than folding the screen part. That includes tilting
sideways. The accelerometer works fine anyway, so i still dont know what
those alerts were about.
With respect

Greetings.
On a friend's Lenovo Thinkpad X1 Yoga that i sometimes get to manage i
noticed the following message in the output of `journalctl -f`
thinkpad_acpi: unknown possible thermal alarm or keyboard event
received
thinkpad_acpi: unhandled HKEY event 0x60f0
thinkpad_acpi: please report the conditions when this event
happened to ibm-acpi-devel@lists.sourceforge.net
This message appeared as i was folding the screen backwards. This is a
"convertible" laptop, i.e. you can fold the screen past 180 degrees.
Almost 360 degrees in fact. This enables it to be used as a tablet
also. So on Windows when you fold it past a certain point (about 180
deg), then the input devices on the "top" side get turned off:
keyboard, trackpoint, trackpad and also keyboard backlight. On Linux
the keyboard and keyboard backlight do get turned off at the same
point (as theyre supposed to). It feels as if the thing blocking
keyboard input is mechanical rather than software/firmware, since i
physically cant press the keys down any more. Currently i made a
script to turn off the trackpoint and trackpad. But as a trigger i can
only use the final state of reaching the 360 deg fold as a trigger
(which shows up in acpi_listen).
This message gets launched 2 times (so 6 lines of text) when folding
past the 180 deg point and again 2 times when folding back to normal
position (90 deg e.g.). *But* this message only gets launched when the
movement is slow enough - when i do it quickly it doesnt show up at
all! I havent booted Windows to check out how this nuance behaves there.
Also is there any way i can harvest this event to launch my own scripts?
If there's any other help i can provide (logs, tests, observations)
let me know. Im a novice Linux user, so i dont know what im doing, but
i can make a few scripts and i managed to stumble upon the 2 commands
i mentioned in this post. Ill continue to have access to this pc for
another 3 days and after that access will be (certain but) sporadic
(unless i learn how to get to their home network with ssh (i did read
how to do it if i had my own server, which i dont)).
All the best
