After my computer shuts down, I still have the power to the keyboard and mouse. This causes both the keyboard and mouse to have lights that remain lit while the system is off. How do I change this, so when I shutdown these also turn off?

  • If your computer has an on-off switch on the power supply at the back, where the cable goes in, and you turn that off, does that disable the lights on the keyboard and mouse?

  • @RandolphWest - Yes that does but having to do that every time can be a real pain.

    I asked the question to confirm my suspicions. Certain motherboards don't actually disable power to the USB ports after shutdown. This is by design, so you may be out of luck.

  • Hmm, I will be looking at the paperwork to see if I can disable this in the settings. Thanks for the info.

  • I posted an answer. However, do you know what your make and model of motherboard you have?

This is normal with some motherboards. It's due to the +5v AUX being active. Some motherboard have a jumper that can disable it. You can also check your BIOS to see if you are able to disable a setting that allows your system to be awake via keyboard or mouse signal.

Your best bet is to read the motherboard's Owners Manual to find a solution on exactly how to disable it for your motherboard.

  • Thanks for your help, I read that in the manual last night. I am just not comfortable messing with jumpers etc in the computer. I can change a video card or RAM but I generally leave the rest alone. But I will look into it. After looking through the BIOS I did not see any option that might allow me to disable it. What is interesting is if I have the power switch off then turn the power switch on the keyboard/mouse do not show any power going to them. Only after shutdown. Thanks again for your help.
