What to do when the computer is turned off and the optical mouse light is still lit?

Reason analysis:

The reason for this is that the atx12v power supply is now on the market in order to achieve advanced power management functions, after the computer shutdown did not cut off all the voltage supply, but to retain a group of power supply for the motherboard, so that the hard disk in standby, so when the optical mouse on standby, it will be light lights.

1, press the DELETE key to enter the BIOS setup program, find and choose to enter the "Power Management Setup" interface;

2, find "S3 KB wake-up Function" or the meaning of similar options (such as "Resume on KBC", "Resume on PS/2 Mouse", etc.), and then use the mouse to move the key to "Disable", the USB mouse needs to be "usb Wake-up from S3 "set to Disable".

3, for earlier models of the motherboard may also need to change the motherboard jumper, for some early listing of the old model Board, because the motherboard BIOS function is relatively single, these motherboards can only use jumpers to turn on or off the keyboard mouse boot function, So to turn off the keyboard and mouse boot function we have to change the corresponding jumper connection status, detailed operation method to see the instructions.
