## Firmware

HP does not provide update files for Linux. Download a file for Windows and using offline USB storage update does not work.

To update BIOS:

- connect laptop to a LAN
- enter bios by pressing `ESC` on boot
- check for BIOS updates
- follow instructions for upgrading or roll back

## Tablet mode

This laptop has a sensor built in to detect if it is in tablet mode.

When in tablet mode, the keyboard is disabled. Auto rotation with `iio-sensor-proxy` does not work at the moment.

## Fingerprint Reader

This laptop has a fingerprint reader.

The fingerprint device is supported by `fprintd`. The firmware needs to be upgraded via `fwupd`.

Currently, `fwupd 1.6.x` is buggy and does not let you update your device correctly. Downgrade to `fwupd 1.5.x` to install the correct firmware.

## Common problems

### Fn lock, Fn+Shift

Fn lock and `Fn+Shift+key` combinations do not work with BIOS firmware `1.05.00` and `1.04.02`. Roll back to BIOS `1.03.00` version to fix.

### Touchpad unresponsive

Touchpad stops working with BIOS `1.03.00` sometimes. Reboot or restart `hid` to fix:

    # rmmod i2c_hid_acpi
    # rmmod i2c_hid
    # modprobe i2c_hid_acpi
    # modprobe i2c_hid

This can be executed at boot for a quick fix, e.g. via a systemd service.

### Auto-rotation

Auto-rotation does not work [1].
