Iam unable to adjust screen brightness in windows7

are you pressing the Function key first? the brightness buttons do not work without pressing that first. usually it is in blue close to the ALT.
& Win key
You can also change your brightness from the control panel, click on display then color setting, and you can see the contrast and brightness, as well as gama that does make it brighter or darker as well. Remember to write down the default settings.
these will not affect playing movies, the brightness adjustment for that are different controls, they can be access by the right click on the mouse during playback

Dell Inspiron 9400 laptop display problem

First power the system on using Fn+Power and see if the diags run and you have video. If you have video in the diagnostics, then I'd suspect the video card as the failure point.
Also connect an external monitor and press Fn + F8 to activate the VGA port If you get video on an external monitor, I'd suspect the LCD as the failure point.

How do I unloopmy dell inspiron 9400 computer? It

The computer is indicating to you that it is unable to detect the presence of the hard drive. You might try booting the computer from the system CD/DVD to repair or restore the drive. (that's what the F12 menu is about) If unable to restore the system, you may need to replace the hard drive.
Any chance that you still have a warranty?

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

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!!
