Reason: Hardware table needs adjusting and a function keys section needs to be added (Discuss in Talk:Acer Cloudbook)

At least four different versions of this laptop exist: AO1-131-C9PM and AO1-131-C620 with a 11" screen, and AO1-431-C2YR and AO1-431-C7F9 with a 14" screen. All of them also have slightly different hardware (e.g. wireless card).

## Hardware

Processor: Intel Celeron N3050 @ 1.60GHz

Video: Intel Corporation Device 22b1 (rev 21)

Audio: Intel Corporation Device 2284 (rev 21)

### AO1-431-C2YR

Device | Working?
--- | ---
Intel graphics | Yes
Wireless | Yes
Audio | Yes
Touchpad | Yes
Webcam | Yes
Card Reader | Yes
Bluetooth | Yes

Wireless NIC: Qualcomm Atheros QCA9565 / AR9565 Wireless Network Adapter 802.11b/g/n (rev 01)

### AO1-431-C7F9 (possibly)

Wireless NIC: Intel Corporation Dual Band Wireless AC 3160 (rev 83)

### BIOS configuration

- Touchpad: Basic
- Boot Mode: Legacy
- Boot priority order: the eMMC block device needs to have a lower boot priority than the USB bootable device.

Then save and exit.

### Kernel parameters

Without these options, the installation image will not load at all:

- edd=off
- noapic

Therefore these parameters needs to be added at the end of the kernel parameters' line of the boot launcher:

    linux /vmlinuz-linux ... edd=off noapic

### Installation

- Everything should function without any issues thanks to the previous kernel parameters, proceed to install the image as normal.
  - The module for the wireless NIC is included with the kernel, so Wi-Fi works out of the box.
- Do not forget to add edd=off noapic to the kernel parameters of the boot launcher's configuration file.

## Installation (UEFI mode)

- No additional kernel parameters are needed.
- The UEFI firmware may be hardcoded to boot from Microsoft's EFI boot loader at `/EFI/Microsoft/Boot/bootmgfw.efi` (tested on AO1-431-C2YR, BIOS 1.06)

### BIOS configuration

- Touchpad: Basic
- Boot Mode: UEFI
- Boot priority order: the eMMC block device needs to have a lower boot priority than the USB bootable device.
- Secure Boot: Disabled, or use BIOS menu to trust the Arch ISO bootloader.

Then save and exit.

## Troubleshooting

### GDM

If Gnome/GDM is installed and started, the login page will flicker up-to the point that it becomes nonfunctional. See GDM#Use Xorg backend.

### High load average on idle

The kernel module rtsx_usb_ms is loaded at boot time yet is non-functional (the kernel thread associated to the module when inspecting with top is a zombified process) and unnecessary for the system to function. The module can safely be blacklisted.

### Bluetooth

At least in AO1-431-C8G8 bluetooth device is deactivated via RF-kill by default. After activating it works flawlessly with bluez.
