I finally got a mouse and for some reason it shuts down my chromebook when it goes to sleep mode

I have not used mice on my chromebooks until now, it's for sure more comfortable then just using the track pad but this mouse shutting it down is annoying. I guess I could just unplug the mouse when I put my chromebook to sleep but I don't get how the mouse could do this to begin with. The only thing I can think of is the mouse has built in LED's on the outside that stays on even when the chromebook goes to sleep. Any ideas that could help?
