Hello,
I have an issue. It is a common one and there are a lot of answers on here, but I couldn't fix my problem. Anyway, my problem is that my motherboard outputs power to my mouse. How do I fix that. I know it's usually less than 5V, but it's annoying having a glowy thing on your desk.

My motherboard is AsRock - G41M VS3

Thanks in advance :)

Try turning on "ErP" in your bios..

"What exaclty is ErP in BIOS?
ErP Support determines whether to let the system consume less than 1W of power in S5 (shutdown) state. When the setting is enabled, the following four functions will become unavailable: PME Event Wake Up, Power On By Mouse, Power On By Keyboard, and Wake On LAN."

I know about ErP and I have tried to find it, but failed... There isn't even a power management tab in my BIOS

EUP_LAN and EUP_AUDIO jumper design decreases the power consumption of this motherboard to meet EuP standard. With an ASRock EuP ready motherboard and a power supply that the 5VSB power efficiency is higher than 50% under 100mA current consumption, your system is able to submit EuP standard. The default setting (short pin1 and pin2) is EuP enabled. If you want to disable this power saving function, you may short pin2 and pin3. Please be noticed that when EUP_LAN jumper is set to enabled, the Wake-On-LAN function under S3 (Suspend to RAM), S4 (Suspend to Disk), and S5 (Soft Off) will be disabled.
