So i bought the lapdock for 60 bucks cause i thought what the hell i dont have a laptop and maybe this will work well enough for that anyway. i bought extension cords for it cause i didnt want to shave plastic off it and then not having the option to return it. I plugged it in with just the hdmi cord cause the other extension cord for the usb wouldnt fit in well. When i plug it in it shows the welcome to webtop 3.0 screen but the mouse wont work. ive tried hitting the led twice and ive tried a usb mouse and it wont work. i also dont know if the keyboard is working either. i tried the 'fn' and brightness etc and it wouldnt do anything. any advice to get this to work?
