Abstract
A method for clearing data stored in a complementary metal-oxide semiconductor (CMOS) chip of a computing device. The computing device further includes a CMOS jumper connected to the CMOS chip, and a general purpose input/output (GPIO) interface connected to the CMOS jumper. The method configures a GPIO pin of the GPIO interface as an output port, controls the GPIO pin to generate a GPIO signal with a high level, and outputs the GPIO signal with the high level to the CMOS jumper. After receiving a command of clearing data stored in the CMOS chip, the method pulls down the GPIO signal from the high level to a low level, to clear the data stored in the CMOS chip.
