I have a Toshiba Satellite A105 s2236 and recently took it it in for repair. When I brougth it home and turned it on, the screen was blank. I had a friend look at it and he said there was a black colored wire was dislodged underneath the keyboard and had no idea how to fix it. However he was able to tell me the person removed the bottom of the laptop and believes that is how the wire dislodged. Is there any way I can fix it without having to pay more for repairs?
