    It is weird, but I don't know how to go about troubleshooting this. For about a week already, when I turn on my computer, 'space', 'e' and '3' doesn't work for a while. I didn't find this too troublesome as it did start working after a couple hits or just after a little time, but now it sometimes just doesn't work at all. Sometimes a restart helps, sometimes it doesn't.

    What might be the issue? I have an ASUS K501U laptop. Could it be the connecting wire?

    Best regards,

    If it's only a few keys, it's not likely a wire issue. When is the last time you cleaned the keyboard?

    I've had dirt/dust cause problems in the past.
    A shot from a can of compressed air fixed it for me.

    Yes, but first turn the laptop upside down and gently shake and tap the underside to loosen particles caught between the keys. You might be surprised at what comes out!

    The keyboard is sort of integrated, check the pictures of the laptop model. I am not sure whether any compressed air will help. Also the button press physically doesn't feel anyhow wrong.

    Does the onscreen keyboard work when the laptop one doesn't for space, e, and 3?

    Connect a USB or bluetooth keyboard. If you don't have one, ask a friend to borrow one. Does the USB/bluetooth keyboard work?

    This might be the US replacement keyboard for your laptop

    A frame fits over the keyboard.

    Yeah, the onscreen keyboard works. I'll try to get my hands on a usb keyboard, but not sure how could that help, asides of having another keyboard :D

    Well if the onscreen works and a USB/bluetooth works, this tells us it is not a software issue because the keyboards work properly when Windows is running.
    You are then looking at a hardware problem.

    You'd have several options:
    1. Use the onscreen keyboard or a USB/bluetooth keyboard when the laptop keyboard doesn't seem to be working
    2. Replace or get the keyboard replaced.

    That's true for any laptop, but wouldn't prevent you from carefully turning it upside down and tapping the underside to see what falls out of the keyboard. Do you think it likely that food particles and other debris might have accumulated? If so, it's an easy attempt to solve the problem while you're looking for a usb keyboard to follow up on plodr's suggestion.
