Some USB mouse will keep LED light up when system power shut down, this is because motherboard will provide USB connector 5 volt stand-by power in BIOS default setting. You might enable EuP function to turn off the 5 volt stand-by power. Then USB mouse LED will not light up. Please go to BIOS> Chipset> EuP Control to set it [Enable], then save and exit the BIOS setting to let it work.
