Users questions: Newly installed computer, occasional light off after the mouse has defects, sometimes normal, and sometimes shutdown display a signal light is green, I ask how this is going on?
Experts answer: motherboard, keyboard and mouse causing boot feature is turned off after the mouse is still luminous in the most common reasons - for real Keyboard and mouse are switched, Wake on LAN power management features such as the current mainstream market ATX12V power supply will provide +5 VSB to the motherboard power supply. In other words, mainstream ATX power supply shut off and not cut off all supply voltage, but retains a +5 VSB power output board So motherboard, keyboard, mouse and other hardware in the standby mode. 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 will light. If the motherboard only supports PS * 2 keyboard and mouse boot, then use the USB interface for power after the mouse off the mouse will be able to solve the problem is still 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 menu did not close, then the mouse will be in the shutdown has been in standby mode. 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 use In tel chipset motherboard 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 scan the mouse will still be bright.
