Mouse

Over a year ago I had the charging port changed on a laptop. Shortly after that the build-in mouse device would work one time I restarted the computer the net it would not. Installing the drivers only helped once after they where installed. I happen to have a mouse that I used for a desktop and was using it. Fast forward  to about a month ago I started have WIFI issue(no profile, would not connect even when code was typed in) then I restarted it one day and no log in screen just black screen where the log in should be. So I recovered and was able to have the computer backup my files. I had gotten use to using the usb mouse that I did not think to check the laptop one but I hit it one day and it worked. Turned it off three nights ago and the built-in mouse driver is gone again. Should I just leave it only or see if the drivers will work this time?
