questions about the backlit keyboard

Is the light always on or I can turn it off manually? Or it goes out automatically when out of use for a certain time? And how is the color of the light? White or kinda blue? I have so many questions and thank u guys~I'm talking about e6400

 

Which laptop is it, and most laptops usually come with an Fn key to shut off the light.

 

On the E6400, the lights on the backlit keyboard are white. They can be configured through Dell ControlPoint and turned on and off quickly by holding down the "FN" key and pressing the right arrow key.

 

There's actually three modes for the backlighting: always off, always on, or ALS dependent. In the always off state, it backlight never turns on. In the always on state, the backlight turns on whenever you type. In the ALS dependent state, the backlight turns on whenever you type, depending on whether the ALS thinks its dark enough to warrant it. Or that's what I've determined by playing with mine.

By default, I don't think that there actually is a way to keep the backlighting on all the time, but there might be a hack or something?

 

In the Dell Controlpoint software, you can also adjust the brightness of the keyboard lighting, if you want to do that.

 

you could turn on the turn off time to 5 minutes or whatever the highest is and itd probably be around the same, but i agree.

 

always find ur answer the most helpful~ So the settings u mentioned r done by software?

 

Even without the Control Point software you should be able to flip through these default modes. As others have mentioned, the CP software allows you to tweak it further; you can adjust the brightness, set it to stay on longer, etc.

 

i have an hp hdx18 laptop i was owndering how do i put the backlight on ?

 

Off-topic, but here goes: press Fn+Space. If you have a backlit keyboard, you'll find a symbol on the left side of the Space key.

HP even created a page covering that.
