This looks like your Laptop keyboard has an integrated Numpad. It is active when enabling NumLock.

Your Laptop Numpad might have small drawings of numbers on right part of your keyboard with the following mapping:

jkl -> 123

uio -> 789

m -> 0

Disabling NumLock should give back those keys their primary function.

1. Hit Shift+NumLock several times to disable Numlock.
   
   You might also have a combination with the Fn keys depending on your Laptop model.




2. If for some reason you are unable to get it done with your physical keyboard, this should help:

   
   
   
   
   
   1. execute onboard in a terminal. This will open an on-screen keyboard.
   
   
   2. click 123, then NumLock. After every click check if your Laptop keyboard is back to normal.
   
   
   
   
   

   

Notes:

• On Mac keyboards the NumLock button is likely to be labelled "clear".
