Would you like to install a new keyboard on your Dell Inspiron 9400 or E1705 laptop? It’s easy. Check out this keyboard replacement instructions. All you have to do is remove the keyboard bezel, remove two screws securing the keyboard (I marked them with red circles on the picture above), unplug the old keyboard from the motherboard and replace it with a new one.

My previous post explains how to add more memory and upgrade the video card.

If you are replacing the keyboard because of missing or broken keys, check out my previous post about fixing individual keyboard keys. Maybe it’s not necessary to replace the whole keyboard.

First, you’ll have to remove screw seals from the screen cover. For that you can use a small flathead screwdriver. In my case there are two sticky screw seals on the top of the screen cover and four rubber plugs on the bottom. Remove all six screws securing the screen cover.

Now you can start removing the screen cover. For that I usually use a guitar pick. Insert the guitar pick (or any other piece of soft plastic) between the display covers and slowly move it along the side until all plastic latches are disengaged.

Finally, remove the screen cover. In order to remove dust, you’ll have to clean both the back side of the screen cover and LCD screen with soft cloth. Assemble everything back together.

This guide shows how to remove the display panel assembly from Dell Inspiron 1200 and 2200 series laptops.

The display panel has three key components:
1. LCD screen (displays image)
2. Inverter board (power up the LCD backlight lamp)
3. Video cable (carries data signal for the LCD screen and power for the inverter board)

If you have a problem with the laptop video and not sure witch component is the culprit, it make sense to replace the whole display panel assembly. You can find replacement parts for Dell Inspiron 1200 and 2200 laptops here.

Troubleshooting tip:

Let’s say your laptop displays garbled video. Test your laptop with an external monitor and find out if the external video output has the same problem. If both internal and external video have the same issue, it’s not related to the display panel assembly. There is something wrong the the laptop motherboard, video card or memory

The disassembly guide doesn’t explain how to take apart the display assembly but you can find these instructions in the official service manual here.

don’t worry about which color antenna cable connects to which connector on the card. With the diversity antenna system used by all wireless LAN cards, it doesn’t matter!
