problem with newly changed laptop screen


Nov 17, 2014
my laptop screen stopped working since it fallen down from 20cm height. laptop was working with external output completely well.
i get it repaired and technical say me that "display must be changed"
they changed the display and laptop worked for some hours.
after a shutdown the display becomes very very dim. repeatedly i refer to my technical he test the system for working and say no problem even in waking from hibernate and standby. my question is that would this problem comes from batter charger of my laptop or not.
