I borrowed this laptop from my son and noticed that on numeric side, only 5 and 6 work but the others fail.
bios is current 65CNWW
uninstalled keyboard drivers and reboot, not solved.
some mention right side altgr , ctrl, and windows or fn key , not solved.
before considering hardware failure, is there any other option that i can test ?
all the best.

Welcome to the Lenovo Community !
I would try plugging in a USB keyboard. If that works without problems then I would suspect the laptop's keyboard is at fault.

You could trying reseating the ribbon cable for the keyboard to see if that makes a difference. There is always the slight chance of a poor connection. If that doesn't work then I again suspect the keyboard has failed and needs to be replaced.
Fortunately for older systems, sellers like eBay and Amazon offer replacement keyboards at a reasonable price. Here is the U.S. replacement U310 keyboards are in the $10 to $12 (US) price range.
Your model's Hardware Maintenance Manual will explain how to remove your existing keyboard for the replacement. Because you will need to remove the fan and heatsink to access the keyboard screws, you will need to also have some thermal paste for the reassembly of the heatsink. If you are not comfortable working inside your laptop then see if a local repair center will replace the keyboard for you.
Here is a link to that manual for your reference.......
