My acer aspire 5515-5187 lcd screen does not show a picture when computer is turned on. I purchased a cable to contect the laptop to my tv, and now I can see the laptop screen on my tv, but the laptop mouse pad is not working. I tried a replacement laptop screen, bt it didn't work either, so I am assuming the problem with the screen not showing anything is the inverter needs to be resplaced. Will a bad inverter also cause the mouse to not work? if not, does anyone know what I could do to make the mouse work, even if I don't replace the inverter right away?
