Hello Everyone,
I need the specialist opinion and help.
I have just builded a pc ,which is working great exept one major problem:
THE MOUSE AND KEYBOARD STAY LIT(LIGHT) ON AFTER SHUTDOWN.
Everything is shut down exept those two.
I have look in BIOS for S3 setting but it is disabled.
I am guessing that it is not MB problem as the PC works great.
Any help appreciated.
Thank you very much.
My PC Spec
CPU:AMD Phenom II x6 1100t
MB:Asus Crosshair IV Formula
Cooler:Noctua NH-D14SE 2011

In my experience some of the USB ports on ASUS boards keep power so that the device connected to them can wake up the PC. Try connecting the mouse and keyboard to different ports.

There is also, usually either a jumper on the motherboard, or a setting in their bios to turn off "power to USB" when it's shut down

mouse and keyboard lit

Hello
Unfortunatelly there is no option in BIOS or jumper to shut off usb.
MY Motherboard is ASUS CROSSHAIR IV FORMULA.
Please let me know if you find an option or if you know about a jumper and where it is located on my MB.
Thanks

I had this on my old Asus p5k with a logitech g11 keyboard. Never did find out why it did it but it never caused any issues.
