Abstract
An electronic device includes a microcontroller (MCU) and a central processing unit (CPU). The CPU enters a sleep mode. The MCU determines whether a charger device is inserted in the electronic device according to whether power is supplied from the charger device, and wakes up the CPU when the charger device is inserted in the electronic device. After being awakened, the CPU detects a type of the charger device, and adjusts charging current from the charger device to the electronic device according to the type of the charger device.
