USB Ports Power Control¶
All four USB Type-A ports on LattePanda Sigma support power control. The Font USB 2.0 port, rear USB 3.2 gen2 port and the USB 2.0 pin header can be set separately.
Path: BIOS Setup -> Advanced -> Power Management -> Always On Rear USB Port/Always On Front USB Port/Always On USB PIN Port
You can set it enabled or disabled. The default setting is disabled.
|Always On USB Port||Power Control of the USB Port|
|Enabled||Run: Enabled; Sleep: Enabled; Hibernate: Enabled; Shut Down: Enabled|
|Disabled||Run: Enabled; Sleep: Enabled; Hibernate: Disabled; Shut Down: Disabled|
|Enabled means the USB port can output power; Disabled means the USB port cannot output power.|
When the LattePanda is disconnected from the power supply, all USB-A ports and the MCU power control are powered off by default. When the LattePanda is reconnected to the power supply and not turned on, the USB-A ports and the MCU power control remain off.
To turn on LattePanda without pressing the power button, please set Auto Power On in the BIOS.
Path: BIOS Setup -> Advanced -> Power Management -> Auto Power On
The default setting is Disabled.
