* The keyboard FN switch in the firmware settings is not effective, the media-keys layer is disabled. (The second layer can be enabled with the EC driver in the future)

=== Checking battery status ===
If the EC driver is not used, you can check the remaining battery capacity with this script:
<syntaxhighlight lang="shell">
#!/bin/sh
raw_dynamic="$(sudo i2ctransfer -f -y 2 w1@0x76 0x07 r10)"
raw_static="$(sudo i2ctransfer -f -y 2 w1@0x76 0x08 r10)"
remaining_charge="$(printf "%d 256 * %d + p" $(echo $raw_dynamic | awk '{print $5, $6}') | dc)"
full_charge="$(printf "%d 256 * %d + p" $(echo $raw_static | awk '{print $8, $7}') | dc)"
echo "$((remaining_charge * 100 / full_charge))"
</syntaxhighlight>

Acer Aspire 1 is a low-end Windows on ARM laptop, based on Snapdragon 7c Gen1, a platform that has great mainline Linux support due to some Chromebooks sharing the same platform.

Variant differences

While the most common version of the device seems to be the "WiFi" variant, an "LTE" version with 8GB ram seem to also exist.

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

Warning 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.

See Windows on ARM devices page for generic suggestions.

Known Issues

Work-In-Progress Issues

Kernel package in pmOS follows upstream Linux and only contains the changes that were accepted there.

Here are some differences between pmOS and WIP branch:

Feature pmOS WIP Notes
Hall Effect/Lid sensor Partial Partial The sensor is reported, but can't be used for wakeup yet.
Audio Partial Partial Internal mic is not implemented yet.

Other issues

  • The keyboard FN switch in the firmware settings is not effective. By default the media keys will be on top (press Fn to input F1, F2...) and Fn behavior can be swapped via sysfs.
  • Using DisplayPort/HDMI audio requires restarting PulseAudio (run pulseaudio -k after the cable is plugged for the sound output to be detected.
