Today I explain how to remove and replace the keyboard on an Alienware Alienware m7700 D9T.
First of all, turn off the notebook, unplug the AC adapter and remove the battery. Make sure you work in static free environment.
Removing the keyboard from this notebook was easier than I expected.
You will find four small latches located above the functions keys, I pointed them with four arrows.
Carefully release latches one by one with a sharp object, you can use a small flat head screwdriver.
When you push on the latch, the keyboard will lift up a little bit and the latch will stay open.
After all four latches are open, lift up the top side of the keyboard.
Move it towards the screen so you can access the cable connector.
Now we are going to unlock the connector and release the cable.
WARNING! Be very careful with the cable connector. It’s soldered to the motherboard and if you accidentally break it, you will have to replace the motherboard.
On the picture below you can see the connector in the LOCKED state.
Lift up the left side of the cable retainer and open it up at a 90 degree angle.
On the next picture you can see the same connector in the UNLOCKED state.
Now you can pull the cable from the connector and remove the keyboard.
You can find a new replacement keyboard if you search using the model number printed on the back of the original one.
In my Alienware m7700 I found two different numbers on the label:
Model number: MP-03753US-4302
Part number: 80-D90T0-011-1
Replace it and assemble everything back together.
