Fixes & Enhancements
- Fixed the issue where an error message is displayed when you update the BIOS exe after performing the BIOS recovery function.
- Fixed the issue where the screen flickers when you adjust the brightness that is already at 100% in Dynamic Display System.
- Fixed the issue where the system does not power on when connected to the AC adapter. This issue occurs when you power on the system after it has shut down due to low battery.
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.
