If the C-State function of the PC is enabled, some symptoms may occur.

C-State is a feature that switches the CPU to a low-power mode to reduce the power consumption of the PC. This feature can cause insufficient power supply via USB, resulting in video delays and unstable video display when using devices such as USB cameras.

In Windows 10, C-State is specifically enabled for the purpose of extending battery life and saving energy.

C-State is a separate feature from the energy saving mode in the power plan. If changing the power plan from Energy Saver or Balanced to High Performance does not help, it is recommended to disable C-State.

It is possible to disable C-State from the BIOS, but since the BIOS settings vary depending on the manufacturer, it is difficult to generalize the specific operation method.

For instructions on how to disable C-State, please contact our support.
