Electronic equipment with sleeping control circuit and sleeping control method of electronic equipment

2011 
The invention discloses electronic equipment with a sleeping control circuit and a sleeping control method of the electronic equipment. The electronic equipment comprises a CPU (Central Processing Unit), an internal power supply unit and a load element and also comprises an external power supply unit, wherein the internal power supply unit and the external power supply unit are simultaneously connected with a power supply selection switching circuit, one output end of the power supply selection switching circuit is connected with the CPU through a first voltage transformation chip, and the other output end of the power supply selection switching circuit is connected with the load element through a second voltage transformation chip. Through the electronic equipment with the sleeping control circuit and the sleeping control method of the electronic equipment, provided by the invention, the residual electric quantity of the internal power supply unit or the external power supply unit is monitored in real time, and a corresponding sleeping policy is adjusted, so that the average power consumption is reduced, the electric loss is reduced, the service life of an internal power supply part of the equipment is prolonged, and meanwhile, external power supply equipment is better protected.
