whughes,
It is a way to save the battery. you can make the screen brighter by using a keyboard command. You will find this info in your setup guide.

....or by changing your power scheme. But the laptop will not run as long on battery power.

also ,why i asked this question is, when my power cord is plugged in, you have to wiggle it a certain way for the screen to stay bright. is the power cord ens wearing out or is it the pin inside the computer. im no tech wizard but i do know the outside of the plug and the inner prong are power and nutral and you need both to complete the circuit. so i need to buy a new power suppy cord?

It could be a faulty adapter - if a new one doesn't fix the problem, then it's a faulty power jack (i.e., mainboard).
