Suspend to RAM - Wake Up by USB Mouse

You can wake up your device by mouse click or key press.

The wake-up functionality strongly depends on the hardware and BIOS version in use. We recommend testing this function before using it. With devices converted by UDC3/OS Creator (OSC) or UD Pocket, it only works when the hardware is fully supported.

Setting System Suspend as the Default Action

  1. In Setup, go to System > Power Options > Shutdown.

  2. Activate Allow system suspend.

  3. Under Default action, select "Suspend".

  4. Save the setting by clicking Apply or Ok.
    From now on, the system will be suspended to RAM whenever it is shut down.


To use the wake-up functionality, the following steps must be performed:

Configuring the BIOS for PS/2 Mouse and Keyboard

  1. Open the BIOS of your device and check if the power management section has parameters named "PS/2 Wake up from S3" or similar.

  2. If present, set the parameters to enabled.

  3. Save the BIOS configuration and continue booting.

Configuring the BIOS for USB Mouse and Keyboard
