## Summary

The 2nd generation of ASUS ExpertBook 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 is 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

This article or section is a candidate for merging with Power management/Suspend and hibernate.

Notes: The issue is not unique to this particular hardware. It is better to document in one place. (Discuss in Talk:ASUS ExpertBook B9450CEA)

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.
