Is there a way to turn off the annoyingly bright blue light?

I don't think so, I cover it up with a handkerchief. I think other people use tape.

No, you can not turn off the blue led light while its being charged. Yes, it stays on when the appliance is fully charged.

It has blue light when you plug the USB cable with the computer, and it turns off if you unplug it.

I just disconnected the blue LED. It's pretty simply. Pop the control panel from the front, not sides... GENTLY! Watch out because the filter reset buttons will just fall out. You have to unscrew another housing underneath the control panel to get to the light. I simply snipped it off with wire cutters and re-assembled everything. Works fine.

The LED is mainly used for showing which DPI speed you are at. You can't turn it all the way off using the included setpoint software. The closest you can get is set it to blue (darkest color) and add enough DPI profiles so that only one of the lights is lit up. As well, while using the mouse your finger pretty much covers up the lights.

I find the one light it has very distracting, so just put a small piece of dark tape (I used electrical tape) over it, and no more problem for me!

Yes. But you will need to manually select if you want the blue light or the white light.

You have to unplug it for the blue lights to shut off....for some odd reason. It is normal for this product.

Yes. Lights up with a blue light. Very cool. You can also turn it off if you want. :)

There must be a way since it's always been across the top of my screen. Now I'm curious to see if I can turn it off.

Yes you can, I have mine set to red because the blue light is almost blinding.

There is a function key on both sides of the keyboard on the bottom, and controls on the F Keys at the top to adjust screen brightness, volume, and keyboard back light. You can make it as bright as you want, and turn it off completely.

There is an option in Windows 8 Settings to turn automatic brightness off. Tha should solve this issue

Yes, the blue led light is very noticeable in a bedroom with lights off. You could probably cover it with tape.

There is a mode where you can turn off the nightlight, but not the display light. I put ducked tape over it and now it is fine.

The constant blue glow definitely keeps me awake, unless I turn the display to the wall AND push it into the drapes to block all the light. This is annoying because then it's hard to set the controls, which have to be re-set every time you turn it on.
