# Lenovo ThinkPad L430

Summary help replacing me
This article covers the Arch Linux support for the Lenovo ThinkPad L430 laptop.

## Troubleshooting

### tpacpi-bat

There is an issue with tpacpi-bat not reporting the right value for the stop threshold. This seems to be related to a buggy BIOS and can not be fixed application wise.

See https://github.com/teleshoes/tpacpi-bat/issues/44

### Trackpoint

There are some issues regarding the trackpoint on the ThinkPad L530 and L430 series. See https://bugzilla.kernel.org/show_bug.cgi?id=33292

A possible solution to enable the trackpoint while keeping a functional trackpad is to install a specially patched kernel module which can be found in the AUR (elantech-tp-dkms).

Warning: This is just a quick and dirty workaround. The following solution will remove the two-finger-scroll functionality of the touchpad. Scrolling is still possible by holding the trackpoint's center button and pushing the trackpoint in the direction you wish to scroll.

Load the kernelmodule psmouse with the options proto=bare:

    # echo "options psmouse proto=bare" | sudo tee /etc/modprobe.d/trackpoint-elantech.conf

Reload the kernelmodule, the trackpoint should now be usable:

    # sudo modprobe -rv psmouse && sudo modprobe -v psmouse
