I assume that you are referring to the Numlock LED on the keyboard.
A PC with an ATX style motherboard and power supply is NEVER fully off unless you physically un-plug it, or switch off the AC power.
The front panel switch simply signals the motherboard to tell the power supply to turn on the computer.
What you have happening is related to the 'free' night-light that some users get when they install an optical mouse.
Your PC never shuts off the 5 Volt power on the PS/2 or USB port.
This is left on to support wake on lan, and wake on keyboard functions.
Having the lights on the keyboard stay on is part of the 'normal' consequences of the wake-on- functions.
If the LED bothers you, you can try disabling the Wake-On functions in BIOS settings, or check for a jumper to disable the wake-on-keyboard function.
