When I unplug the power cord from my laptop the screen brightness automatically dims down to about 10% of its total brightness, and when I click the quot;increase screen brightnesskey on the keyboard the brightness will only increase about 5% until it stops. It's like I've put some limit as to how bright the screen can get. Anyone know how to fix this?
This is standard on laptops. The display takes a lot of power so it is set to dim when there is no mains power. You can go to Control Panel, Power Options and change this. You will need to tell it that this isn't a laptop.
I'm not sure if this will fix it but I have an idea. Do you know where the charge level in on your computer. I have the inspiron 1520 so it's an old version but on mine it's on the bottom right hand corner. If you click on that you should get a screen that pops up and gives you the amount of battery life it has left in a percentage then underneath that it should have a select a power plan: area and the options that it gives you are balanced, power saver and High performance. If you click on the high performance then the brightness should be the same weather the power cord is plugged in or not. Hope I helped =)
