Fixes & Enhancements
- Fixed the issue where the Alt Gr key on the keyboard does not work before you boot into the operating system.
- Fixed the issue where the CPU speed runs at a lower frequency when VT and VT-d are disabled in the BIOS setup. This issue occurs when the system resumes from sleep mode.
- Fixed the issue where system cannot connect to the BIOSConnect server with all the supported WLAN cards.
Important Information
- Do not power off the system until the process of updating the BIOS is completed.
- Once the BIOS is upgraded to version 2.0.0 or later, you cannot downgrade the BIOS to version 1.8.0 or 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.
