This guide is going to show you how to replace the keyboard, But first, we need to remove whatever covers the keyboard. So this is going to be time-consuming. Be patient!
Before you start your replacement, make sure that you have powered off your laptop completely

Grab the two clips beside the RAM stick and pull them outward. The RAM stick should release.
-
Remove the RAM from the device.

Repeat this for second RAM stick

After opening the backcase of the computer, remove the screws using the Phillips #0 screwdriver.
-
Unplug and remove the wire from the socket.

-
Remove the fan and heatsink from the laptop.
Why do you have to remove the heatsink when it can just be lifted out with the motherboard?

-
Use the pull tab on the battery connector to lift the connector straight up off its socket on the motherboard, disconnecting it.
Personally, I would remove the battery as the first stage battery should be disconnected before any work is completed.

Remove the single 4 mm Phillips screw securing the bottom left corner of the battery.
-
If you are removing an extended capacity battery, remove the Phillips screw securing the bottom right corner of the battery.
My laptop had 2 screws holding the battery. I am not sure why. It may be useful to check whether yours has 2 as well. Unlike the laptop’s back cover, after unscrewing the screws on the battery, you have to remove the screws.
I too have 2 battery screws. My battery is longer than the one pictured. I think my battery must be an extended capacity battery.
What I do not understand is that in the picture, on the extreme right - next to the computer's outside edge, there is a round CMOS battery pictured with a red/black twisted pair of wires plugging into the motherboard. My machine has an empty space with no battery. What about the machines of others? Was there one that has been removed? My machine seems to work ok without it. Should I install one?

Remove all the screws using a Phillips #0 screwdriver.

Disconnect all of the cables from the motherboard.
In order to access the two screws near the docking port, you need to remove the docking port cover. This is released by removing the two screws on the rear edge of the case and then lifting the part clear - assuming you have removed all the other screws.
The screws on the board are hidden by the two-round caps, on either side of the docking port.

Remove the keyboard from the device.
I have the E7470 without the pointer and the keyboard isn't backlit and it doesn't have the palm rest above the touchpad. I have found a backlit keyboard on eBay (unlike the keyboard in this tutorial) that looks identical to mine but only has 2 ribbons. I'm guessing one for the keyboard and for the backlight. My motherboard has a spare connector next to the main ribbon (here are the pics of my motherboard and the keyboard I'm referring to: https://www.dell.com/community/Latitude/... - the 2 pics at the bottom of the thread). The connector I'm referring to is the same as the one marked by the red square on the far right of the pic at Step 10 of this tutorial. Am I correct in assuming that this is the connector for the backlight?

Very useful photos. Keyboard changed successfully. Thank you.
Also was able to change keyboard successfully.
Will note that there are some screws noted for motherboard and keyboard that already removed in previous steps. Was confusing for a bit.
An interesting discovery - the keyboards for the UK and US versions are slightly different, and annoyingly don't fit.
However, an excellent guide - thank you for taking the time to compile it.
