My acer aspire 5515-5187 laptop lcd screen stopped working. the computer indicates it is on, but no display on the screen. I think i've narrowed the problem down to the inverter. In the mean time until I find an inverter, I've connected my laptop to my tv so I can see the screen display for my laptop on my tv. The problem now is the laptop mouse isn't responding. Does anyone know anything I can do to fix that problem?
