The XiaoXin-15ARE 2020 is primarily sold in China, the most similar internationally sold model is the IdeaPad 5 15ARE.
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.

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
