Optical Mouse
 

I just got a new computer with an optical mouse. When the computer shuts off, it goes into sort of a sleep mode, but the optical mouse light doesn't shut off. Is it ok for it to be on? I believe it is an LED and they dont' really burn out frequently. Do I need to unplug it when I'm done?
Thanks.

nah it's fine. LED's are bomb proof and use like, no power at all.

i had a problem like what ur discribing when i got my new computer it would go in to a sleep mode when i shut down and all the lights would still remain on.
after a while it just stoped happening
i was told that it was my power supply it wernt up to mark to push my hardware. (300w)

but nuthing serious came out of it! so i would'nt worry too much!
