Fixes & Enhancements
- Fixed the issue where the admin password window is displayed when you run the Pre-Boot System Assessment (ePSA) in the BIOS setup.
- Fixed the issue where the ESC key on the system keyboard stops working in the BIOS setup. This issue occurs when an external USB keyboard is connected to the system.
- Fixed the issue where the system stops responding at the Dell logo while booting.
- Fixed the issue where the power button LED of the dock does not light up. This issue occurs when the dock is connected while the system is in Modern Standby, and the system lid is closed.
Important Information
- Once BIOS is upgraded to version 1.4.2 or later, you cannot downgrade the BIOS to earlier versions. 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.
