I finally fixed my laptop and was able to re-install windows on a new hdd yesterday. After booting it up for the first time everything worked fine. I plugged it up to my TV and it worked like normal as well, but when I unplugged the cable the laptop screen stayed black. When I restart it the ASUS boot up screen appears as well as the windows logo, but after that it stays black and i can only see anything when I have an external monitor plugged in. I even tried to access the screen resolution to see if the problem was there but it doesn't even show my laptop monitor as a choice, just my TV. Any help would be much appreciated!
