Switching off a Razer Mouse

Question

This may comes as a 'huh' question, but let me explain. I have a Razer gaming mouse which has a really bright red laser light. If I power down the computer, but leave the power outlet on, the mouse still emits light, which is quite annoying. Any idea how to get the red light to go off when I power down the computer?

Answer 1

These mice take their light simply from the USB power, without needing to have the system on. It's on the electrical point of view, there is nothing to turn it off in the mouse itself.

However, there is probably a way to tell your computer to cut the power from USB when it's off. I'm not sure, but it could be from a "USB wake-up" option in the Bios (giving you the possibility to wake up the computer from a USB device). So you could check your Bios about such option eventually.

If not, then it is probably something with your motherboard, and besides turning off the back switch, or unplugging the computer, I don't see a way to fix this.

Answer 2

I also have a Razer mouse and keyboard, both with plenty of lights. Great when gaming in the dark. But when I turn off my computer, the lights are turned off too!

I think the problem is not the mouse but the computer, which doesn't seem to switch off completely. It's likely that it's set to awaken again after you press a key or move the mouse, or something silly like that. Some computers are able to turn themselves on again if commanded to do so from an USB device, thus they leave some power on the USB port. The mouse thus receives power and thus keeps the light on. It doesn't know that your computer is off.

If you've put your computer in sleep mode instead of turning it off completely, this is expected. Otherwise, it could be a BIOS setting that will enable power to the USB devices.

(Btw, this is useful when you're recharging e.g. a TomTom or other rechargable device through your computer!)

Answer 3

You might use a powered USB port.
For example, the Buffalo BSH4A02 USB Hub gives you maximum control:

(No idea where it's sold and for how much, though)

Answer 4

Haven't tried it, but this might work:

1. Enter Control Panel / System (Hardware tab on XP).
2. Click Device Manager.
3. Click the + at Universal Serial Bus Controllers.
4. Right-click on the USB device representing your mouse and select Properties.
5. Open the Power Management tab.
6. Check Allow the computer to turn off this device to save power.
7. Click OK.

or it might only work for sleep.

Answer 5

This answer does not turn your mouse off, but it is what alot of us do to cover all those beeping bright LEDs that manufacturers insists on putting in our devices...

... we tape them up, with strong, non-residue, highly-opaque insulating tape, so they'll never see the light of day (pun intended).
