I checked the settings, and the only way I can make the screen brighter is to go outside in the sunlight or shine a flashlight on it. I know cell phones have this too, but at least you can shut off the auto-brightness and keep it bright all the time. Doesn't seem to work on this. I tried to do that and nothing, it stays at the yucky dim screen. I don't really care about conserving battery, my keyboard has a one built in and I have a spare battery to carry on long trips away from a power source. Does anyone know a override? I tried calling Dell, they want to replace the screen. It is under warranty, but they can't see that the last seller had switched it in my name. I had the email confirming this, But that was on my Latitude 10, Dell replaced that with this.... But now the tech idiots can't see that. I would like to get this done before August, I will not renew a warranty that I have to fight to get fixed every time I need help
