Laptop screen brightness issue
Hi all. I am having issues with the screen on one of our school laptops (Acer Extensa 5620G) having a very dim display. Have done some research on the internet and come accross a couple possible solutions (Bios update, replace inverter), none of which have worked. I have taken the lid apart and swapped both the screen and the inverter with spares that I know work, to no avail. Anyone have any idea what the problem could be? I have heard re the inverter that it is a power issue? Could there be a probelm with the motherboard connection or something similar?
