重要信息
- You must install Intel Graphics driver version 4274 or later and then install BIOS version 1.1.4. This step resolves the blurred screen issue.
- This update does not support BIOS versions before 1.2.7. You must use the executable file to update the BIOS.
- Once the BIOS is upgraded, you cannot downgrade the BIOS to version 1.1.5 or earlier. 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.
