Have you open your computer recently

One of the LED switches on the motherboard may have been knock around or falled or shorted.

On the motherboard there is a couple of wires that connect the case to the motherboard like Hard Drive LEDs, Power Switch, LEDs, reset switch There are little wires like one wire per pin.

These wires are very annoying because there are hard to connect them and you have to be careful of what pin you connected to and not to brake them.

It sounds like they have have shorten or failed.

Posted Image

Look right hand bottom near the edge you see 9 pin those pins have wires connecting to the case

There not much you can do at this point. The wires are directly wired to the case.

I would check if any of the wires are damage or frayed. It might be just lose.

The computer still works
