and test the video cable and it also works. As shown in below picture I want to know what this white part(it has a 322 number on it's surface)? fuse or something else? I can't find laptop schematics.

Unfortunately, I don't have schematics. On one of it's sides there is 19.0 volts and on the other side there is no volt.

the part is marked as 322 and it cant be crystal. Let the part remain removed and power on the mb and check voltage on both pads of that part. Its likely to be a fuse but first check voltage reading.

i'm sorry for the wrong answer from, since i don't have schematic or boardview and i can't find it, i can't make sure what was that. I said it crystal cause i found on some board have crystal like that near lvds con and i don't read clearly your post that said it was marking part. Glad to hear you solved your problem
