Fixes & Enhancements
Fixes:
- Fixed the issue where the system stops responding at the Dell logo screen when it resumes from hibernate mode. This issue occurs when the Discrete Graphics Controller Direct Output Mode is enabled in BIOS.
- Fixed the issue where a user acceptance is prompted to proceed with the BIOSConnect recovery when network stack is disabled in the BIOS.
Enhancements:
- Updated the Intel Management Engine firmware to 12.0.72.1757.
- Updated the graphics names in the BIOS to match with the graphics names in the operating system.
Important Information
- Once the BIOS is upgraded, you cannot downgrade the BIOS EXE/Recovery (RCV) to versions earlier than 1.0.5 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.
