Hi there,

Try doing it in the BIOS environment.

-To enter the BIOS environment Tap F2 while on the DELL splash screen after turning the computer on
-A BIOS update might work but do it with a DELL representative so that whatever may happen they would know immediately
-If the behavior is the same it might be a good idea to send the laptop to them because either the buttons are stuck or there's something wrong with the controller of the brightness and contrast

Hope this helps!

After re-installing Windows, you also need to install the laptop's device drivers eg. LAN, audio, video drivers etc.
You can download the drivers from Dell WEB site, thesupport download page. Make sure you select your model desktop or laptop,better still, type in the Service Tag number, it is printed on the label on thebottom of the laptop and on the back or sides of a desktop. (If the Service Taglabel is missing then go into the BIOS setting and on one of the BIOS pages,the Service Tag number will be displayed). This will open the page where thespecific drivers for your model computer are located. Also make sure you selectthe Windows XP or Vista version of the drivers for your Windows operatingsystem. Click on this link to download the drivers: - http://support.dell.com/support/downloads/index.aspx?c=us&l=en&s=gen

I have install win 7 for my dell inspiron 6400 laptop but no modem & no video controler


You need to go to Dell Support pages online and download the drivers for your laptop model, if they dont show a windows 7 driver then try the vista or xp one they list, should still work.

How do I adjust brightness on my Dell Latitude D6...


Look for a key labeled "Fn" (blue lettering) on the lower left side of the keyboard

Hold the "Fn" key and then use the Up/Down arrows to adjust brightness.

If that doesn't work, reboot your laptop and get into the BIOS. There is a screen for brightness. I don't recall how it is labeled, but it's one of the last pages as you cycle through the BIOS options.

Hi there!

Try to change the setting of the brightness in BIOS,
You can access bios by pressing f2 after you turn on the computer, then you will see brightness there, max out the brightness.

If it still does not work then go to the power options of your laptop then change the setting of the brightness when the charger is plugged in.

Hope this helps!

Just boot from XP CD - pressing F12 should give you the option in Bios, allowing you to boot from CD when all is completed. Some PCs still need sata/scsi drivers loaded by pressing F6 in the install. If all fails read original manual that came with Dell 6400. If lost you should be able to download from dell support, using express service tag.

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!!
