LCD Screen Stays Dim on Dell D630

We have received a brand new Dell D630. The problem is that the LCD display continually dims. If you cycle power, the LCD display is briefly at normal brightness then it proceeds to dim again. We have tried different AC adapters and different batteries. We have tried running it on just battery and running it solely on AC power (without the battery plugged in).

Is this a hardware issue or is there a tweak or something that we are missing?

Have you tried going into the BIOS and setting the LCD brightness setting from there? If the BIOS setting is at the max then it could be a manufacturer defect.

Have you try pressing on holding the Fn key and hitting the up arrow, or sometime there is a F# key that has a sun with an up  arrow.

Yes, we have tried using the keyboard controls to increase and decrease the dimness.

As it's brand new, make use of your warranty!

It sounds like to me the ambient light sensor on the D630 is turning on.  If you boot into the BIOS you should be able to disable it.  Also in Vista you can turn off when the screen dims/ shuts off.  If you go to control panel, system and maintenance and then power options you can change when the LCD Dims.

It was hardware. Dell replaced the LCD.

Thank you for your assistance. I didn't want to call Dell unless I had to do so, so at least it wasn't a wasted call.

We reseated the LCD cable under the keyboard and resolved this issue. (At least for now). It may have just been loose from the factory.

Pry off the top trim piece (with the Latitude label, power button, etc.)
Remove the 3 screws at the top of the keyboard
Rotate the keyboard toward you and lay it down upside-down. (don't detach it)
The LCD cable on ours had a blue tag on it. Just pull it up gently and then re-attach it.

A laptop or notebook is a portable personal computer with a clamshell form factor, suitable for mobile use. Although originally there was a distinction between laptops and notebooks, the former being bigger and heavier than the latter, there is often no longer any difference. Laptops are commonly used in a variety of settings, such as at work, in education, and for personal multimedia. A laptop combines the components, inputs, outputs and capabilities of a desktop computer, including the display screen, speakers, a keyboard, and pointing devices (such as a touchpad or trackpad) into a single unit. The device can be powered either from a rechargeable battery or by mains electricity from an AC adapter.
