Updating the BIOS in Windows

Prerequisites

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 before initiating a BIOS update.

About this task

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.

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 Base Article:
