Main causes
One of the main reasons why the lights on your keyboard and mouse stay on is due to a setting in the BIOS that allows USB power to remain active after shutdown. This setting is typically used to allow USB devices to charge when the computer is turned off.
To manage this issue, you need to go into your computer’s BIOS settings. Inside the BIOS, look for settings related to USB power management or something called “ErP Compliance”. Changing this setting may cut off power to the USB port after the computer is turned off.
BIOS Setup
To change these settings, you need to enter the BIOS setup. The trick is to press the F2 or Del key when the computer turns on. After entering the BIOS, look for settings related to USB power or similar settings that allow power to continue to flow to the USB port after the computer is turned off.
Troubleshooting Steps
- Enter BIOS: Restart your computer and press F2 or Del to enter BIOS.
- Look for USB Power Settings: Navigate to the power settings menu and look for options related to USB power.
- Disable Settings: Disable the option that allows USB power to remain active after shutdown.
- Save and Exit: Save the changed settings and exit BIOS.
