## Firmware setup

You can access the BIOS by pressing `F2` at the Splash screen. The boot menu can also be accessed by pressing `F12`.

### F2 and F12 keys do not work

The Windows 20H2 installer (consumer edition, updated Feb 2021) is tested to delete these keys' functionality to reach BIOS settings and Boot menu. It is unclear whether Microsoft intentionally did this or is yet another bug in Windows. You can try return your laptop Lenovo to repair mainboard BIOS information.

It is recommended to update to BIOS version `E7CN42WW`, as in #BIOS update, which fixes this issue.

### Noto Button

You can also use the "Noto Boot Menu" which displays more options like BIOS Setup and Boot Menu. On power on, press the power button while holding `Fn` to access it. Note that this is also affected by #F2 and F12 keys do not work, so if the `F2` and `F12` keys do not work, "Noto Boot Menu" cannot either.

### Enter Firmware Setup Utility without F2 and F12 keys

See Unified Extensible Firmware Interface#Enter firmware setup without function keys.

## Firmware

No Fwupd support is present on this device.

### BIOS update

BIOS updates can be found here: 小新-15 2020(AMD平台：ARE版) 驱动列表 under the BIOS section. Only a Windows installer is provided. Extracting with innoextract (version 1.8 tested) can unpack the downloaded BIOS-E7CN39WW.exe to E7CN39WW.exe, which is the Phoneix's BIOS installer. But this installer cannot be further extracted with innoextract.

It is recommended to update to BIOS version `E7CN42WW`, which will fix `F2` and `F12` keys problem. It also adjusts thermal control so that the fans are more quiet and more efficient. The update will reset UEFI boot order to only contain Windows boot manager; return to Arch Linux after BIOS update by following the steps in Unified Extensible Firmware Interface#Boot back to Arch Linux when stuck with Windows

## Power management

This laptop has 3 modes of system performance mode available: Intelligent Cooling, Extreme Performance and Battery Saving. To toggle it, you need to call some ACPI methods, which require an out-of-tree kernel module. See Lenovo IdeaPad 5 15are05#Power management

## Wireless

Wi-Fi Direct (aka Wi-Fi P2P) support is only present on Windows: in Windows cmd, see `netsh wlan show drivers`.

1. The key is visible to `xev` and similar tools. Desktop environments and even some window managers may come with a default configuration which swallows all the function keys, since it is handling them by itself. This visiblility column is tested on a minimal window manager Openbox with `xev`.
2. The physical key has a symbol on it, which describes its function.

### Toggle Fn lock in UEFI/BIOS Setup Utility

Besides `Fn+Esc`, you can also change Fn lock in UEFI/BIOS Setup Utility. In UEFI/BIOS Setup Utility, Configuration > HotKey Mode, change to Disabled to use `Fx` for direct `Fx` key, `Fn+Fx` for function key (HotKey), change to Enabled to use `Fx` for function key (HotKey), `Fn+Fx` for direct `Fx` key.
