The only “clue” is within the system configuration that my setup is not original - but then again, neither is the LCD - went to HD+ when the base HD panel had issues. The machine accepted the keyboard like it was shipped that way even though I added it on 6 months into my ownership. Note that the layout includes a dedicated number pad, which is extremely handy. I did it on my E6440 because it originally shipped with the E5 non-backlight single input keyboard, and it worked fine. is the presence of the extremely versatile Windows 10 Touch Keyboard. 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’s to the point I prefer to seek out a backlit spec machine unless I know it can be done. With this machine, you can often find the backlit version for a few bucks more. Right-click on Start menu(1), then select Device Manager(2). Update drivers through Windows Update Intel Serial IO controlled driver a. After installing these drivers, please restart your PC then check whether the Touchpad function is working or not. The DP/N is 564JN (US English Backlit) or M8F00 (US Engligh non-backlit). Download and install ASUS Precision Touchpad driver.

That said, check if the numlock key is dead (lock with 9 as the “key”), or not active - sometimes you get lucky. Dell seems to have more keyboard issues then Lenovo, 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 then some other brands.
