linux – My keyboard recognizes keys only when i´m pressing tab

The “a”, “s”, “d”, “k”, “i”, “-” and “m” keys of my laptop´s keyboard only work when I´m pressing tab.

If I don´t hold tab the computer doesn´t recognize them (I checked on the browser and with showkey). Sometimes when it starts up it doesn´t recognize any key.

The laptop´s OS is Debian 10.
