Now most people use photoelectricity mouses, but have you ever found such a symptom: after turning off the machine normally, the mouse still keeps radiating, why? How to solve the problem? Next let’s introduce a little tip about how to “let mouse not radiate after turning off”.
Solution:
Keyboard/mouse startup function of motherboard is the most prevalent reason for the situation. Generally motherboard BIOS all provides setup for keyboard/mouse start function. You could enter BIOS primary menu “Power Management Setup” and find “S3 KB Wake-Up Function” or an option of similar meaning, and set it “Disabled”. Stop motherboard’s ＋5VSB power supply for keyboard/mouse, after machine shuts down, of course, PS/2 photoelectricity mouse would not radiate. Besides, some USB photoelectricity mouses would still radiate even after the machine is shut down. The solution is similar to PS/2, enter BIOS primary menu “Power Management Setup” page, set “USB Wake-Up From S3” or option with similar meaning as “Disable”.
