I have Lenovo ThinkPad X1 Extreme Gen 2 that I spilled some water on last week. I waited a few days then tested it out and found that the keyboard was typing q1 w2 e3 r4 instead of q w e r for the entire row and a few keys are also not working.

I tested with an external keyboard and it worked fine so I thought I would need to replace the keyboard. Now the new keyboard is also having similar issues, although fewer keys are affected. 

I uninstalled the driver and tested on both Windows and Ubuntu (dual boot) to verify that it's not a software problem. 

Here's the keys not working on the new keyboard: q w e r t u y i p 1 2 3 4 5 6 7 8 0 turn into q1 w2 e3 so on. The column 9 o l . doesn't work at all.

Hi,

I'm afraid that some water penetrated the motherboard... Check your motherboard for oxidation and try cleaning the keyboard connector carefully. Then make sure to reconnect properly the keyboard ribbon cable into the connector.

Good luck

Thank you for the reply. When I took the laptop apart I didn't see any visible water residue so I'm not sure if that's what you mean by oxidation. I would appreciate some pointers to how I can check that.

The keyboard is connected to a sub card, which in turn connects to the motherboard, so the problem could also be there, although I didn't see any signs of water damage either. 

I will check it out again with an external keyboard

Inspect the motherboard (and other components) closely for any damage caused by water, like corrosion, rust or signs of discoloration. Pay attention in particular to the connectors as they are more vulnerable to corrosion.
