Updating the BIOS in Windows
It is recommended to update your BIOS (System Setup), when you replace the system board or if an update is available. For laptops, ensure
that your computer battery is fully charged and connected to a power outlet.
NOTE:
If BitLocker is enabled, it must be suspended prior to updating the system BIOS, and then re-enabled after the BIOS
update is completed.

Updating BIOS on systems with BitLocker enabled
CAUTION:
If BitLocker is not suspended before updating the BIOS, the next time you reboot the system it will not recognize the
BitLocker key. You will then be prompted to enter the recovery key to progress and the system will ask for this on each reboot. If
the recovery key is not known this can result in data loss or an unnecessary operating system re-install. For more information on
this subject, see Knowledge Article:
