Built-in keyboard was suddenly remapped

Hello!


Here are the keys that were suddenly remapped in my keyboard:


1 -> F2

2 -> Esc

3 -> none

4 -> Esc

F1-12 -> Esc

Spacebar -> Esc

Insert, Del, Home, End, PgUp, PgDn -> Esc


*Esc, F1-12, Insert, Del, Home, End, PgUp, PgDn are all at the top row of this keyboard.

**I used Keyboard Tester to determine the functions. The same inputs were recorded when I used a keyboard remapper as a temporary fix.


Here are the things I've tried so far:

1. Change the input method.

I tried switching to different English inputs.​


2. Turned off Sticky Keys and Filter Keys.


3. Attempted to update the keyboard driver.

I tried to update via Device Manager, but it says that the latest driver has been installed.​

I looked at the manufacturer's website for drivers, but was not able to find anything for my PC's model.​


4. Attempted to roll back drivers.

Roll back option was not available for my keyboard driver.​

Tried to roll back Synaptics PS/2 Port Compatible TouchPad, because I've read somewhere that this could be relevant to the issue and that it worked for them.​


5. Disabled touchpad.

Same reason as to why I tried to roll back its driver.​


6. Reinstalled the keyboard driver.


7. Uninstalled Notepad++.

I know that its less likely to have this app cause the issue, but I thought it was worth a shot. It was the last app I installed before the issue, but it still was working fine and I still got to use the app for about 30 minutes until the sudden remapping.​


8. Ran the keyboard troubleshooter.


9. Checked Windows Update.

My issue occurred on 09/04/2020, but the last update installed on 08/30/2020 and it was working fine until 09/04, so it's less likely that the culprit is the Windows Update. I also checked if updates are to be installed, but it shows that my PC is up-to-date.​


There might be some other methods that I tried but missed to include in the list. I tried so many after all, but I'll add them in this post if I'd recall.


Here are the current details of the PC I'm using:

Edition: Windows 10 Home​

Version: 2004​

OS Build: 19041.450​

Keyboard Driver: Standard PS/2 Keyboard​

Device model: Toshiba Satellite L850D​


Keyboard replacement may not be an option, since this was purchased in a different country, and it is an old model. Right now, I used a keyboard remapper so I could use my space bar to actually input space as a temporary solution, and thankfully, it has a numpad so I don't always have to use the on-screen keyboard. I tried to make this post as exhaustive as I can, and it would be greatly appreciated for anyone who could help me out on this one.


Thanks a lot for reading through!
