Users questions: After the keyboard or mouse off light still lit? Sometimes bright and sometimes does not shine, you must pull the mouse and keyboard line before off! How is it?
Experts answer: mouse keyboard motherboard mouse boot caused the shutdown function is still glowing after the most common The reason - in order to achieve keyboard and mouse boot, power management Wake on LAN, etc. Management function, currently on the market mainstream ATX12V power supply will provide +5 VSB to the motherboard power supply. In other words, mainstream ATX power supply shut off does not cut off all supply voltage, but retained a group of +5 VSB output board power supply, motherboard, keyboard, mouse and other hardware in the standby State. Since most motherboards now support the PS * 2 keyboard and mouse boot, so after the power is still off the PS * 2 for the board is powered, so that the mouse is in the standby mode, this time the most obvious feature is the optical mouse light still scanning shine. If we motherboard only supports PS * 2 keyboard Mouse boot, then use the USB interface for power off the mouse after the mouse is still able to solve the problem light. But now there are many motherboards support both PS * 2 and USB keyboard and mouse boot, this time whether you use PS * 2 or USB interface, optical mouse, keyboard and mouse as long as the boot function Not closed, then the mouse off and would have been on standby. So to solve this problem the most fundamental solution is to close the Main Board of the PS * 2, USB keyboard and mouse boot function. In addition, the mouse light does not disappear after the host is off a lot of motherboards using the Intel chipset specific Phenomenon. Because the Intel chipset without cutting off 220V electricity supply situation (that is, there is power supply), the USB port will provide random voltage 0.9V-2.5V output, if this time we are using a USB optical mouse, then the scanning mouse will still be bright. Turn off the keyboard and mouse in the BIOS boot feature is currently in the vast majority of motherboards have BIOS provides boot function on the keyboard and mouse set, you can enter the BIOS main menu "PowerManagementSetup" page, find "S3KBWake-Up Function "or the meaning of similar options (such as" ResumeOnKBC "," ResumeOnPS * 2Mouse ", etc.), set it to" Disable "close the Main Board of the keyboard and mouse +5 VSB power supply, PS * 2 optical mouse off Followed by natural there would be no bright.
