Numbers are typed instead of letters

This is another common problem which is also usually related to software. Sometimes it happens when we press a digital lock by mistake.
The fix - Press “Fn + Numlock” or “Fn +Shift + NumLock” simultaneously. This will disable the numerical lock and will be solving the issue. The key combination will depend on your laptop model, so just try both.
These are some of the tips to keep your keyboard free of problems as far as some common issues are concerned. But if after trying all the above options if the problem persists and you still end up with your laptop keyboard such as HP Keyboard not responding still, then it is recommended to take the machine to a service center for professional advice.
