Why is my number pad not working?
My number pad (right of the keyboard) is no longer working, as if the NUM Lock is off. there is no physical NUM LOCK key, so I have no idea how to fix this myself.

Dell seems to have more keyboard issues at least in my experience with the E6540 - granted my E6440 was fine with the original keyboard before I did the keyboard/palmrest swap, but it does happen on these more than other brands like HP and Lenovo. That said, check if the numlock key is dead or just disabled (lock with 9 as the “key”) - sometimes you get lucky.
The DP/N is 564JN (US English Backlit) or M8F00 (US English non-backlit) if you need to replace it. With this machine, you can often find the backlit version for a few bucks more. All you have to do is transfer the flex cable since this isn’t tied to something like the motherboard to upgrade the keyboard type on these machines (which is a variable on the E7 to the point I prefer to seek out a backlit spec machine unless I know it can be done). I did it on my E6440 because it originally shipped with the E5 non-backlight single input keyboard, and it worked fine, even without the buttons. The machine accepted the keyboard like it was shipped that way even though I added it 6 months into my ownership to replace a bad one. The only “clue” is within the system configuration on the S/T that my setup is not original - but then again, neither is the LCD as I upgraded it to HD+ to fix a bad 768p (HD) LCD.

Hi,
Check if Number Lock has been disabled in BIOS.
Start the laptop and press F2 before the laptop boots into Windows i.e. when the Dell logo is on the screen.
When in BIOS use the arrow keys to navigate through the menus.
Go to the Post Behavior menu > Numlock Enable and verify that it shows enabled.
Here’s the service manual for the laptop. See p.64 for how to enter BIOS setup and p.70 for the Number lock entry.
