Lenovo ThinkPad E15 Gen 4 (Intel)
Installation
Secure Boot is enabled by default in the latest Lenovo laptops. Thus, Secure Boot has to be disabled first if you want to install Arch Linux on this laptop, since the "Microsoft 3rd Party UEFI Certificate" is not included in the Arch Linux installer.

Power management
Sleep
The trackpoint and trackpad will stop working after suspend. To fix this issue, change the "Sleep State" option in the BIOS to "Windows and Linux" (instead of "Linux").
Battery control
When controlling the start and stop charging threshold using TLP or /sys/class/power_supply/BAT0/charge_control_start_threshold and /sys/class/power_supply/BAT0/charge_control_end_threshold, setting the start_threshold to a value other than 0 will result in the battery not charging anymore.
Fingerprint reader
The fingerprint reader is supported using libfprint-2-tod1-goodixAUR, although the Ubuntu Certified page says it is not.
