Fixes & Enhancements
- Fixed the issue where the screen does not turn on after the system lid is closed and Do nothing is enabled in the Power Options window in Control Panel. This issue occurs in systems that support the dynamic display switching function.
Important Information
- Once the BIOS is upgraded, you cannot downgrade the BIOS EXE/Recovery (RCV) to versions earlier than 1.2.0 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.
