That is not to worry, but what if I use the laptop 3 cable and laptop 2 or 3 screen (both working), and I try it on laptop 1, and it doesnt work for example. Is there any chance I could damage the cable or something so that when I put it back into laptop 3 I could somehow damage there something? Because I have damaged laptop 1 camera that I wrote when I saw sparks, so I am concerned it could cause some damage to the new things and when I put the new things into laptop 3 cause some damage there too?When swapping cables. Make extra sure that both ends are properly attached. I know it can be tricky at times with laptop internal cables getting them aligned just right.
