I reset athe Elitebook, first a what I call light reset, kept my files. It was getting slow and had to try something. The internal speakers stopped working, trouble shooter was no help like it usually is and various other hick ups. Ended up doing a complete reset. Now along with no speakers detected, my left click button will not work. I can't do anything without left click of course, I tried a wired mouse, nothing. I am at a loss. It was a refurbished laptop that was updated to Windows 10 when purchased. It worked great, but didn't use it a whole lot. Once in awhile one needs a computer instead of mobile device. I have lost some computer savvy and now am stuck. Any suggestions?
