Keyboard does not register the "l" key

Keyboard does not register the "l" key. Windows Surface Book Pro 4, 64 bit laptop, with Windows 10 installed. Have tried ensuring that Windows 10 is updated, suspect that I might need to uninstall and re-install KeyBoard drivers. Marked as high priority as my daughter is trying to complete University essay for today.

Try to find a USB keyboard. If that works, you sadly have a hardware error (physical keyboard needs replacement).
It's never a driver issue if ONLY ONE key is not registering.
If more are not registring (for example, I gives 5, O gives 6, then it's just NUMLOCK problem). If all keys are registering well, but displays other things, it's usually a keyboard/language/region setting.

Can you talk me through how to update the keyboard driver for Surface Book Pro 4?

There are others out there with similar issue:

I have had a similar issue on my corporate Lenovo device, where it did not pick up " key.

Sending back the PC would be a real pain.

Sorry, hardware problems can't be solved with software. As I said, if it's ONLY the "I" key, it's NOT a software/driver problem.
Also the link you sent, was also a hardware issue.
Active Protection takes the fight to cryptojacking

While there were several headline-grabbing ransomware attacks during in 2017, another big threat started appearing at the same time that didn’t get the same coverage – illicit cryptomining.

I concur that it is a hardware issue (could be from isolated liquid damage, something stuck behind the key cover/shield, etc.)

Due to the time-constraint, I recommend using the Windows built-in on-screen keyboard until you can pop the i key out and check for an issue (or replace the keyboard).

click the start menu, type:

on-screen keyboard

then click on-screen keyboard

use the touch compatible keyboard.

P.S. if you have an external USB keyboard to connect to the system that is a great temporary workaround too.

If all fails, (no USB keyboard, onscreen keyboard too laborous), then install the free AutoHotKey app: https://autohotkey.com

Then use this: https://autohotkey.com/docs/misc/Remap.htm

Rremap a less used key to "i"
