In the using process of a product, the problems that the machine cannot be started due to BIOS setting errors or the machine is abnormal in name and the like often occur. In view of the above, technicians usually instruct users to discharge the CMOS first, and then observe whether the computer is normal or not after the CMOS information is cleared. The methods for discharging and clearing the CMOS information mainly include two methods: one method is to adopt a power-off method to clear the CMOS setting, and concretely comprises the steps of remotely instructing a user to open a case cover, finding and taking down a CMOS battery on a mainboard, then using a metal conductor to short-circuit a positive electrode and a negative electrode in a mainboard battery holder, and quickly discharging the stored electricity in a corresponding capacitor in a short-circuit mode to achieve the purpose of clearing the CMOS; the other method is to adopt CMOS to clear the jumper, specifically, firstly, a user is guided to open the case, the CMOS is found to clear the jumper on the mainboard, the CMOS clear jumper is generally a three-pin jumper, normally, a jumper cap is connected to

pins

1 and 2, when discharging, the jumper cap is sleeved on

pins

2 and 3, then the jumper cap is inserted back to

pins

1 and 2 again, and the CMOS is cleared.

In the prior art, the two methods for clearing the CMOS information are not easy to operate, and a case cover needs to be opened to find a jumper wire or a mainboard battery. For the jumper mode, because of having too many jumper caps on the mainboard, the mistake is found very easily. For the mainboard battery mode, the battery is not easy to take out, and the front side and the back side are easy to be mistaken. In addition, if the user's machine is placed on the machine room frame, opening the cabinet cover is also troublesome.
