Summary

The 2nd generation of ASUS B9450 with 11th Gen Intel CPU with Intel Xe graphics.

Models are B9450CEA-* compared to B9450FA-* of the 1st generation.

BIOS

To boot from a USB stick, you may have to turn off Fast Boot and Secure Boot: How to boot the system from USB flash drive/CD-ROM.

Note: You do not have to turn off VMD in BIOS as long as you have vmd module enabled in your initram image wikipedia:Intel_Rapid_Storage_Technology#Intel_VROC_(Virtual_RAID_on_CPU).
Warning: Even though the model line is B9450CEA, in BIOS and on the official support page it's indicated as B9400CEA.

dmidecode will also display Product Name as ASUS EXPERTBOOK B9400CEA_B9450CEA and BIOS Version as, e.g., B9400CEA.301.

Audio

This laptop requires firmware in order for the soundcard to work. See Advanced Linux Sound Architecture#ALSA firmware.

Suspend mode

By default the system supports Suspend-to-Idle mode, which has increased energy consumption during sleep state:

# cat /sys/power/mem_sleep 
[s2idle] deep

To fix that you might want to switch to S3 mode (also known as Suspend-to-RAM or deep) by appending mem_sleep_default=deep to kernel parameters.
