My "D" key does not work unless I press it hard enough. How do I know if it's a hardware issue or a software issue?

I have a Lenovo Ideapad 1 15ALC7, I bought it half a year ago. But my "D" key stopped working unless I pressed it hard enough. I tried cleaning it with one of those air shooters for keyboards, but nothing. I'm not sure how to pry off the key without damaging it. Could it be a software or a hardware issue?

I know this is the Microsoft Q&A page, but I'm not sure who to ask. I've already asked on Lenovo's q&a page also, but I also wanted to ask here just in case.

I also already tried turning off all toggle keys, already unchecked all the boxes under "Make keyboard easier to use" from the Control Panel, turned off Gaming mode.

I read that I should try toubleshooting my keyboard from the system settings, but I don't have that option under "other troubleshooters" or anywhere else for that matter. Is that only a problem on my computer?

Sending the computer to a professional is not cheap where I live, so I was wondering what to do before resorting to that option.

Thank you!

Hello,

This is usually a hardware issue with the keyboard. Underneath the keyboard, there is a circuit board with numerous signal tracks. Cracks in the tracks, dust or debris buildup, or corrosion can disrupt the signal flow. Holding down a different key can send the signal through an alternate track, which is why it sometimes works.

To diagnose a keyboard problem, it's essential to test with the onscreen keyboard or a different keyboard via USB or Bluetooth. If the alternative keyboard works, it's certain that the issue is hardware-related.

Hello!
Thank you very much! I already tested the onscreen keyboard and they key worked perfectly there! So I guess it's hardware then. Do you know how people or professionals usually solve this problem?

Yeah, I fear it is hardware too, because if it is software issue, it seldom just affects one key.

If the keycap can be removed safely, lift it off and clean around the hinge and rubber dome. Dust or debris can prevent a key from making proper contact. If cleaning does not help, the practical fix is a keyboard replacement. Keys that require extra pressure usually indicate a worn keyswitch or damaged dome, or micro cracks on the circuit board. Try not to spam it as pressing hard and spamming can cause any crack to get wrose.

If repair is too expensive, you an always just get a wireless keyboard and use that for now. One of my old laptops has the same issue with a few keys, it is not worth repairing, and i just put a wireless keyboard on it instead.

Thank you very much!
I forgot to add that it started a few days ago while I was playing a game. I first noticed the problem with the "W" key but then it moved to the "D" key suddenly. If I try playing now with just the "W" key, it works perfectly except every now and then it halts for a microsecond and works again. Do you think that could give any more clues to what could be the issue?
Thank you so much for the quick response!

It can be cracks, as it can spread. But without thorough hardware exam, it is impossible to conclude. Sorry.
