Some keys type double letters

Asked by Hannah K. · Screens, keyboards and trackpads2 repliesupdated

For about two weeks my laptop keyboard has been typing certain letters twice. The worst offenders are E, the space bar and the letter N, so a sentence like "need to send" comes out as "neeed to senddd". It is not every keystroke, maybe one in twenty, and it seems worse when I type quickly or when I am tired and my touch is lighter.

    It is a Windows 11 laptop that is about two years old. I rely on a few accessibility features every day, including sticky keys, so I am wary of changing keyboard settings and breaking something I need. I have not spilled anything on it. I tried restarting and updating Windows, and nothing changed.

    How do I tell whether this is a setting, a driver or a failing keyboard? Is there a setting that deals with this kind of repeat, and could one of my accessibility settings be involved? I would like to rule out the free fixes before I take it for repair.

    First test I would do: plug in a cheap USB keyboard and type the same sentence. If the doubles stop, the laptop keyboard is the problem. If they carry on, it is software, and then check the keyboard driver in Device Manager and try typing in Notepad to rule out one app.

    Dust or crumbs under the keycap, I bet. Pop the keycaps off and pour a bit of isopropyl alcohol under the keys, let it sit, work the key up and down. That fixes sticky and double keys every time on my old laptop.
