Important Information
- Once the BIOS is upgraded, you cannot downgrade the BIOS EXE/Recovery (RCV) to versions earlier than 1.3.1 due to restrictions. BIOS downgrades are restricted when there are security updates and important fixes with earlier versions that impact the functionality of the system.
- BIOS updates take no more than 5 minutes to be installed on your system. You can install the updates in the background while using the system.
