    摘要: An example electronic device includes a controller to determine a user touch detection by a power adaptor coupled to the electronic device to operate the electronic device in an AC power mode. The power adaptor may comprise a proximity sensor to detect a user touch for detachment of the power adaptor from the electronic device, and a control circuit to operate a configuration pin in a low output mode to signal user touch detection. The controller may initiate central processing unit (CPU) throttling to reduce power consumption by the electronic device. The controller may further stop CPU throttling in response to detecting that the power adaptor has been detached from the electronic device. Further, the controller may switch the electronic device to a DC power mode to operate using DC power supplied by a battery of the electronic device in response to power adaptor detachment.
