Volume Mute Light won´t change color

I can´t find anything that addresses my actual problem.I have seen that others have also experienced this problem but I have not found a solution that works. My ProBook was originally Win 7 pro, updated to Win 10 pro but HP won´t update because of its age (for me, brand new-just bought it a few days ago) so I don´t really know what to do.
