    Hello, I have had a problem with several keys on my laptop for a long time. Once they work all day, and once I will probably press hard and it will only press once. All of these keys are related because they all don't work and they all work at the same time. I do not work (a, 1.2 shifts and the left and right buttons on the laptop will only press after some time).
    I would ask for help.

    Laptop keyboards usually cannot be disassembled. The only thing that can be proposed after replacement is an attempt to blow it with compressed air. Was it flooded by any chance?

    It just wasn't like that 3 years ago they suddenly stopped working, now e.g. they work again.

    From the description of the symptoms, it looks like a cold solder on one of the resistors between the keyboard connector and the KBC.

    Can it be fixed somehow?

    Yes, locate where it does not connect and correct solder. If you provide the model, brand and preferably the code name of the motherboard, I will try to send the part of the diagram responsible for the keyboard.

    Maybe the tape on the keyboard does not connect?

    The tape is pressed to the "drawn" paths on the PCB, these paths may not exist anymore or are dirty, you could clean them (note, because they can be easily torn off) and connect, I repaired the keyboard in the T40, I do not know if all this is...
