Optical Mouse Light

Well this is kind of a dumb question but here it goes. My Microsoft Optical USB/PS2 mouse lights up red when the computer is one (from the reflected light from the laser on the bottome). When I turn my computer off that light stays on unless I reach behind the computer and flip the switch on the PSU to "off" for a few seconds. Whats weird is then I can turn the PSU's switch back to the "on" position and the mouse's light stays off. This has happened with both my original PSU and the new PSU I just installed. Its kind of annoying because I sleep in the same room as the computer and I hate having this bright red light on all night. Any suggestions on how to fix this other than switching the PSU off and then on again each night when I shut my computer down?

Thanks!
 
You could always put a cover on the mouse, or buy one that shuts its optical light off after a few seconds (MX510 comes to mind.)
 
can you plug it into a PS2 port?

lots of motherboards don't power the PS2 port when the computer is off, or have a jumper that determines wether the computer does or not...

oh, and if it's already in a PS2 port... try a USB port?
 
doesnt the computer have "left over" charge from being on...maybe in a capacitor...so itll keep feeding things power until its all gone...thats why places suggest when going inside your cmoputer to flip the switch in the back and press the power button to drain all remaining charge...
 
some computer have the "boot on ps/2" setting...which is why the mouse still gets power.the mobo has the ultimate control of power you see, and switching off the psu with that switch in the back is almost like when the computer loses power in a lightning storm...its set to remain off if there has been a power loss...a safety feature you see. idk, fiddle with the bios maybe?
