Hi matilda05 ,
Would you have the same problem using the onscreen keyboard ?
How about connecting a USB external keyboard ?
Isolating issue on physical hardware (keyboard) as failing keys may be affected by some applications . This event usually happen with corrupted file and most of the time virus or malwares.
Update us how things go.

There is still possibilities of driver incompatibility with certain Windows 10 builds. Lenovo Vantage would help updating those that are needed for Windows 10.
Else, installing the original Windows version and drivers can help isolate if the issue more.

Perhaps you can go back to Win8.1 for now else use an external keyboard that works. Again, this would clearly isolate it and likewise allow you to use your machine functionally.
