All of a sudden, my D key repeats. I've ruled out software bugs, as it happens in multiple OSes. I don't think I spilled anything on the keyboard. What can I do to fix it?

The keyboard is XArmor U9Plus Cherry MX Blue Mechanical Keyboard. I believe the design was later sold to QPad, so you may know it by a different model (MK-80, or Nighthawk).

To fix this, you'll need the following:

• A keycap puller
• A toothpick or some other similar object
• 90% or higher Isopropyl Alcohol or something very similar
• A syringe or something similar that will allow you to squeeze out 1 drop at a time

What you do is you fill your syringe or similar thing with like maybe 5-10 drops worth of the alcohol (or just fill it - it doesn't matter). Then, with the keycap removed, hold down the switch with your toothpick or similar object (this keeps your finger out of the way), and put about 3-5 drops directly on top of the stem so that the alcohol goes down inside evenly.

Immediately after this, press the switch over and over fairly rapidly in order to help clean it and distribute the alcohol. Keep pressing it fairly rapidly for maybe 30 seconds. After that, find something else to do for about 10 minutes while you wait for the alcohol to try. Or, sit there and hold the switch down for about 5-10 minutes with the toothpick and maybe blow into it from about 8-12 inches away (in order to blow the driest air possible into it).

You may need to repeat this 1-2 times, and you may need to do it every 1-2 weeks for 1-3 months. I had the same problem with my spacebar and I needed to do this about once every 2 weeks for about 2 or 3 months and today, it's fine.

So, this is what I recommend.

You... are a genius!

I didn't have a syringe, but I managed to get some drops down into the key switch. Everything is working so far.

Thank you so much!

Nice. I give credit to this thread that I participated in:

Remember though, you might have to keep doing this for a few months about once every couple of weeks. So, you might not be out of the woods yet, so to speak!
