Abstract
A server power saving system includes a motherboard and a backplane. The motherboard includes a CPLD, a basic I/O control chip electrically connected with the CPLD, and a clock chip electrically connected with the CPLD. The basic I/O control chip includes a basic I/O control program The backplane includes a HD microcontroller electrically connected with the CPLD and a HD connection port electrically connected with the HD microcontroller and the clock chip. The HD microcontroller sends clock enable signal to the CPLD when a HD is electrically connected with the HD connection port. The CPLD transmits clock enable signal to the basic I/O control chip. The basic I/O control chip sends confirmation signal to the CPLD according to clock enable signal, and the CPLD determines whether to drive the clock chip to send clock signal to the HD connection port according to a content of confirmation signal.
