If your keyboard buttons like “ç,” “Enter,” or “Shift” aren’t working, it could be due to a hardware problem or a small driver glitch. To figure out what’s causing the issue, you should start by testing your keyboard online. Visit a website like https://testeteclado.com.br/. This site will show you in real time which keys are responding.
If the problematic keys don’t light up or respond on the test website, it’s likely a hardware problem. You can try cleaning under your keyboard keys gently with compressed air or a soft cloth. If cleaning doesn’t fix the issue, consider testing a different keyboard to see if the problem persists.
On the other hand, if the keys work properly during the test, then the issue probably lies with your software. To fix this, head over to the official HP Support page. Look for your specific keyboard’s drivers, and update or reinstall them. Once that’s done, restart your computer. This quick step often helps your keyboard function normally again.
