This is a hardware survey of the Linux related hardware features of the Lenovo ThinkPad L15 Gen 4 (Intel). I don´t explain installation details like partitioning details, file system details and so on. Requests for additional information may be asked by eMail from the author.
I choose the Lenovo ThinkPad L15 Gen 4 (Intel), because it is the only available ThinkPad model with my preferred FHD (16:9) resolution or a video mode of 1920x1080 pixels with a 15.6" display. Further on it is availabe either with an AMD Ryzen or with a here preferred Intel Core i5 processor.
The machine's ACPI interface works reasonable well with the stock Linux kernel. Standby- or suspend-mode is established by software or the appropriate hardware buttons. The laptop suspends under wayland and console to RAM and disk and restores it's former state in reasonable speed. All relevant FN buttons send appropriate signals when thinkpad_acpi is loaded as module or compiled into the kernel.
Be sure to install the latest BIOS, available at Lenovo's support site.
The machine runs on ArchLinux/x86_64 on top of a plain-vanilla Linux kernel 6.9.8
The only difference to the Lenovo T-series is the missing magnesium alloy roll-cage, But anyway, the L-series also has a reinforced cage and the laptop is thus also as solid as a rock.
The system comes with a amazing fast hybrid 13th Gen Intel(R) Core(TM) i5-1335U (Raptor Lake) processor with 10 cores and 12 threads - 2 performance cores with 2 threads each and 8 effecient core with 1 thread each.

The notebook's got a touchpad with 2 and a trackpoint with 3 buttons. The whole stuff is recognized as a Intellimouse PS/2 and works in the text mode console with gpm started like this:
# /usr/sbin/gpm -m /dev/input/mice -t imps2
The graphical mouse works flawlessly with 'libinput'. Excerpts from my local sway config:
input "10182:481:GXTP5110:00_27C6:01E1_Touchpad" {
dwt enabled
drag enabled
scroll_method two_finger
tap enabled
tap_button_map lmr
}
The keyboard comes quite unspectacular as a generic model with 104 keys with an additional numeric block. The relevant FN-keys work surprisingly well, wenn the module thinkpad_acpi.ko is loaded with options thinkpad_acpi experimental=1. You may define your own key bindings with a properly configured acpid.
The graphical keyboard works with 'libinput'. Excerpts from my local sway config:
input "1:1:AT_Translated_Set_2_keyboard" {
xkb_layout de
xkb_model thinkpad60
xkb_variant nodeadkeys
xkb_numlock enabled
xkb_options compose:caps,terminate:ctrl_alt_bksp
}
There are one Thunderbolt 4, one USB 3.1 Gen2 Typ C and two USB 3.1 Gen1 ports at the chassis.

Works out of the box with kernel modules bluetooth.ko and btusb.ko.
The fingerprint reader is integrated in the ACPI button. I don't need any biometric stuff here around, so I didn't even try to configure it.
The camera is behind a slidable privacy shutter on the front of the LID and works out of the box (hint: see Arch Wiki).
