Go to the “Advanced” → “Customer Exclusive Functions” tab. Make the following change…

• Auto Power On → Enabled

BIOS Setup for eMMC:

Go to the “Chipset” → “SCS Configuration” tab. Make the following change…

• eMMC 5.1 Controller → Disabled

Important -> Disabling eMMC support will prevent booting to Windows.

Save the above BIOS changes, reboot.

Disable CPU C-states: (Optional)

Using the CLI, enter the command:

set-kcmd-cstate help

Read over the help information, if you want to disable C-states, then…

set-kcmd-cstate disable

Tip -> An added benefit to disabling C-states, it eliminates the high-pitched squeal at idle.
