hey, im have an old laptop that i've had stored in a laptop bag for a while. i'm not sure, but i may have stepped on this bag at one point (i dont remember) anyway, when i point/touch the screen, the whole screen looks like it's covered in raindrops. the machine's been stored in a cool room. is it possible that there's some sort of liquid damage? or is it because i (may have) stepped on it? the screen seems to be functioning ok, but it's incredibly noticable that something is wrong when i point at it. any service techs or anyone got any ideas as to the issue? thanks!
