Question Some keys on my laptop's keyboard have stopped working ?

[J-Po]

My laptop is a Lenovo Thinkpad Yoga L13 running Windows 10, and the system is up to date.

Out of the blue, a handful of keys on my laptop have stopped working. The keys are mostly on the left but some are on the right side (on the left: tab, shift, 1, Q, A Z and on the right: delete, down arrow and shift. The control key is behaving strangely on both sides - when I hit control/C, which would normally copy, instead of copying, it deletes.

When I plug in an external keyboard, all the keys work fine with the laptop.

I've seen advice to uninstall and reinstall the keyboard, but I have 2 keyboards listed in my device manager (HID keyboard device and Standard PS/2 keyboard) so I'm not sure which one to delete and reinstall (I updated both of them and nothing changed).

Any advice would be appreciated!

Has the malfunctioning gone thru any stress? Washed with a cup of coffee?
A replacement KB for my Lenovo laptop is all one piece as all the keys are in a metal pan/tray and can be had on eBay relatively cheap! Also it is relatively easy to swap out, on my Lenovo any way.
