Installation

Disabling UEFI Secure-Boot

This device uses the standard UEFI secure-boot. The initial configuration seem to contain the keys for some Linux distributors (i.e. Canonical or Debian) but for now it's probably easiest to just disable it.

Note that the following actions may cause Windows to fail decryption if the Bitlocker was enabled.

  1. Power on the device and press F2 to enter UEFI setup.
  2. Go to the Security tab and set the maintenance password. Write it down.
  3. Go to the Boot tab and disable the Secure Boot. This option is only available if the password is set.
  4. Go back to the Security tab and remove the password by changing it to the empty string.

Installing pmOS on an external storage

You should be able to perform sdcard installation with some usb-stick as the target. Note that the laptop has no SD slot.

Highly consider making a backup of the internal storage, it seems like the recovery media is not available for this laptop.

Installing pmOS on the internal eMMC

Icon WARNING: The bootloader chain of the device is located in the same eMMC as the OS, damaging internal partition layout may make the laptop into an unrecoverable brick.

TBD

Known Issues

  • BT controller seem to crash sometimes, fixed by re-probing the related kernel modules.
  • The external display seem to cause issues in many cases, related to the GPU.
