- Fixed the issue where the system wakes up from the shutdown state through Wake-on-LAN when SMB Provision and Wake-on-LAN are disabled in the BIOS.
- Fixed the issue where the system cannot wake up from Hibernate mode or shutdown through power button. This issue occurs when a device is connected to the system Type-C port.
