Question about Dell Inspiron 6400 Notebook

2 Answers

My Dell Inspiron 6400 is extremely dark. +brightness does nothing

My laptop's screen is very dark. I have to shine a bright line onto it or be in a very bright room to be able to read anything. I've tried the + gamma button but it does nothing? My Dad said something about maybe an Inverter needs replacing? THanks

Hi,

I am newbie to Linux world. I have recently installed Kubuntu on my Dell Inspiron 6400.
I also installed Beryl and had no problems with the installation.

Only thing which I am not able to do is the brightness control using special Function Keys.

Generally Fn + Up arrow or down arrow is used to increase/decrease brightness level. I am unable to do so in kubuntu.

Please help and advise....

Hi there.
Yes, if you can see a very faint image on the screen that indicates that the inverter or inverter coil has become defective and needs looking at or replacing.

Good luck and thanks for using Fixya!!

    Hi there.
    They are both on the inverter circuit board underneath the laptop screen itself, only a qualified PC service engineer will be able to determine which of them it is.
    For the time being however, you can use an external monitor until you have the problem fixed.

My Laptop 6400 screen is very dark, how do lighten? I have replaced battery twice in last 3 1/2 yrs.


ldriscoll3:
The brightness of the screen does not generally depend on the health of the battery.

On the keyboard of your laptop is a "Fn" key. You need to press and hold the key down while you also press the "Up Arrow" key repeatedly. Each time you press the "Up Arrow" key while holding the "Fn" key down, the display will get progressively brighter until you reach maximum brightness. If you go too far and it gets too bright (not likely), just press the "Down Arrow" key while holding the "FN" key down until it's the perfect brightness

This is explained on page 33 of the user manual that you can download from here:

Loss of light on screen Dell Inspiron E1705


Hmm, this could be a problem with the backlight inverter or something as simple as power settings.

In power settings from control panel there should be an option to alter the brightness lever of the screen when on battery.

Have a look in there and set it to default to see if it makes any difference.

Let me know if you need any more help.

Regards

Nick
