Can you Turn off the BackLit LED anytime or no? And does the mouse have LED as well. Can I turn that off as well. What is the warranty on this?

You can turn on and off the LED back light on the keyboard using the scroll lock button. The mouse is permanently lit; no on and off button. I'm not sure about the warranty.

Mouse no, keyboard yes but it's tied to turning on and off scroll lock. Not sure on warranty

The keyboard's back light is easily turned on and off by using the "Scroll Lock" button.The mouse has no button to turn the LED on or off, so it is constantly on.I have no clue about the warranty, but that doesn't matter.

The keyboard LED can be turned on and off at any time. The mouse can not be turned off. the warranty I don't remember you could check with Amazon about that.

You can turn off the keyboard backlight any time. The mouse is lit but you can't turn the mouse off. I think the warranty is a year by not for sure. I love mine

You can turn the led off. However, it makes the keys super hard to see. The mouse does have LEDs. All the blue you see in the picture is from an LED.

Yes the keyboard you have to hit the scroll lock to turn back light on and off. and Yes the mouse has LED lights on. On my mouse it always stays on. warranty All products from Cooler Master carry at least 1 year warranty from the date of purchase. must have prof of pouches. nice Board and mouse for the price.

You can turn it off but only on the keyboard but it's hard to see the letters when it's off. And the mouse has led but it doesn't turnoff ever and I'll have to check the warranty on it when I get home

I only have the wireless mouse. And there is a switch on the back where you can have it on with the led light or without

I generally do not turn the mouse off when it is not in use, so that wastes battery a little, but I'v had it for eight months and I have only replaced the batteries once. I use it maybe 15 hours a week for gaming and I also use it instead of my laptop's trackpad for daily use.

I feel like I have been using my current battery for at least 6 months. And I never turn the mouse off. I bought mine on 8/4/13 and can only remember changing the battery once. It lasts long enough that I don't notice it being a hassle, for sure. I love this mouse.

You can turn the back lighting off. I did not have any issues with the keyboard in the bios. If your computer still powers your USB port when off it is the motherboard not the keyboard. If the computer is off and it is still light up then you can simply unplug and replug and it will go off and stay off.

You cannot turn it off.I have used this mouse for 2 years. Love it. It has been dropped a couple of times, snapped the pieces back in that popped out and still works great.I love it.

Mine is not backlit and the F5 key didn't "turn on" the backlit keyboard option (as another poster mentioned). My F5 key turned the mouse off and on.

Troy may be right. Leaving the USB connected 24/7 may kill the battery. My arrow keys quit after 3 months. Next day the delete key reversed directions! Then the illumination keys quit. Logitech doesn't offer replacement batteries and I think mine is shot.

The keyboard I think isn't the problem as I've had the same batteries in it since I got it and they are fine still. Now the mouse doesn't shut itself off and I've gone through 4-5 batteries in it to the one in the keyboard. If you are having a problem I suggest taking the battery out every time. Yes inconvenient but saves on the battery cost for sure. I'm lazy therefore 4-5 batteries in the mouse. There are no shut down methods that I know for either. but for the price... Try Emailing the company itself they might have a solution.

I never got a chance to put mine on. The computer was stolen. I replaced it once before and believe it is the complete deal. I didn't notice a backlight when I removed it. I still have mine but no where to put it.

I just leave it in the unit and turn the mouse off on the back, there is an on/off button that saves on the battery.

Unfortunately no. The only way to turn it off is to either unplug it or turn your computer off. That is the only flaw I see in this mouse.

The light does stay on to let u know. But it didn't work for me. I still have mine plugged in and I still have a mouse problem. They just wait until night time now to come out and ruin stuff.

Yes a backlight comes on when moved and looks very nice. Also this is one of the smoothest mice I have ever tried.

If you find out, will you let me know? Since getting my new Dell laptop for Christmas, I've bought three (3) Microsoft mice. Each one failed after a couple of months, and I don't even know how to get Microsoft to honor its warranty. The problem seems to be with the antenna/sending unit - have relaced batteries in the receiver, but there's a tiny light on the antenna that doesn't light up one day, and then you're toast. I love these things when they work - am tearing my hair because the third one died last month. Good luck.

You will get a warranty but good luck getting them to actually resolve your problem. We have been fighting with them for months to fix the well known issues with the cursor randomly selecting things or moving. see my review.
