To access the boot menu and BIOS, use "F1". Disable secure boot from the BIOS.
Sometimes the TrackPoint stops working and dmesg reports a stream of garbage when it is touched. Removing and probing the kernel module solves the problem:
# rmmod psmouse # modprobe psmouse
With default configuration, tearing is apparent when playing videos. DRI3 and glamor are supported. To solve tearing and use DRI3 and glamor, create the file
/etc/X11/xorg.conf.d/20-intel.conf with the following content:
Section "Device" Identifier "Intel Graphics" Driver "intel" Option "AccelMethod" "glamor" Option "DRI" "3" Option "TearFree" "true" EndSection

If the device has unusually high CPU usage in idle then it might be an acpi firmware issue. On Windows this behaviour stops after a regular update. On Linux you can workaround by disabling whatever device is interrupting excessively.
Find the interrupting source:
grep . -r /sys/firmware/acpi/interrupts
This might output something like this:
... /sys/firmware/acpi/interrupts/gpe34: 30289 enabled <-- this causes many interrupts /sys/firmware/acpi/interrupts/gpe35: 3 enabled ...
Disable it (as root, not just sudo):
echo "disable" > /sys/firmware/acpi/interrupts/gpe34
Now the CPU should idle at 0-2% usage.
Unfortunately you have to do that on every startup. A systemd service can do that automatically for you.
[Unit] Description=Disable acpi interrupts [Service] ExecStart=/usr/bin/bash -c 'echo "disable" > /sys/firmware/acpi/interrupts/gpe34' [Install] WantedBy=multi-user.target
Then enable the
disable-interrupts.service systemd unit.
