Fixes & Enhancements
Fixes:
- Fixed the issue where the LCD brightness does not change smoothly when adjusting the LCD brightness using the keyboard hotkey.
- Fixed the issue where the power button LED on the Dell dock WD22TB4 does not light up when connected to the system. This issue occurs when the dock is connected after the system has booted.
Enhancements:
- Improved the POST (Power-On Self-Test) time.
- Updated Whisper Mode to version 2.0 to reduce the fan noise.
- Improved the boot time to the BIOS Recovery screen.
- Updated the Thermal Management settings in the BIOS setup to improve the system performance.
Important Information
- Once the BIOS is upgraded, you cannot downgrade the BIOS EXE/Recovery (RCV) to versions earlier than 1.0.1 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.
