If your keyboard isn’t working properly, you can start by checking which keys are not responding. A simple way to do this is by testing your keyboard online. Visit a free keyboard testing website like testeteclado.com.br and press each key one by one. The site will show you whether each key is functioning correctly or not.
If you find that some keys still don’t work even after testing, the next step is to follow the official troubleshooting advice from the manufacturer. For example, if you have an HP keyboard, go to their support page at support.hp.com. They provide step-by-step instructions to help you identify and fix common keyboard issues.
If both the online testing and the troubleshooting steps point to the same problem — with certain keys not responding — then chances are the issue is with the hardware itself. In most cases, replacing the keyboard is the best solution to get your device working smoothly again.
