Common Keyboard Problems
1. Sticky or Non-Working Keys
The cause is often dust, dirt, or liquid that has gotten under the keys. Try cleaning the keyboard with compressed air or a special brush. For mechanical keyboards, you can carefully remove the keys and clean the switches.
2. Keys Respond with Delay
The problem may be related to both mechanism wear and software settings. Check the repeat rate settings in your operating system (response) and disable unnecessary auto-input functions.
3. Repeated Character Input
The key starts typing multiple characters with a single press. This is most often a mechanical problem with the key contacts, requiring either cleaning or switch replacement.
4. No Response to Some Key Combinations
Some keyboards have limitations on the number of simultaneously pressed keys (N-key rollover). This is especially important for gamers and fast typing.
Tip:
Regular preventive cleaning of your keyboard can significantly extend its lifespan and prevent many functionality issues.
