修復及強化
- Fixed the issue where the Dell logo that is displayed while booting is bigger after the BIOS update. This issue occurs when the system is connected to a 4K monitor through a Dell DC dock.
- Fixed the issue where the customized logo and product name are removed when you upgrade the BIOS and change the BIOS to its default settings.
- Firmware updates to address security vulnerabilities.
重要資訊
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.
