Hi @MAYANDKUMAR, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 
It sounds like you're experiencing a couple of different issues:

1. Keyboard not responding properly – You need to press keys multiple times before they register.
2. Black screen in the right-side corner – This could be a graphical issue or a software bug.

Try these solutions:

1. Restart Your Laptop

A simple restart can sometimes fix temporary issues.

2. Check for Stuck Keys or Dust

• Clean the keyboard using compressed air or a soft brush.
• Try an external USB keyboard. If it works fine, the issue might be with your laptop’s keyboard hardware.

3. Update/Reinstall Keyboard Drivers

1. Press Win + X → Device Manager
2. Expand Keyboards
3. Right-click your keyboard driver → Update driver
4. If that doesn’t work, right-click → Uninstall device and restart your laptop.

4. Check for Graphics Driver Issues (Black Screen Issue)

1. Press Win + X → Device Manager
2. Expand Display adapters
3. Right-click your graphics driver (Intel/NVIDIA/AMD) → Update driver
4. If the issue persists, uninstall and reinstall the driver from the manufacturer’s website.

5. Check for Windows Updates

1. Go to Settings → Update & Security → Windows Update
2. Install any pending updates.

6. Perform a System File Check

1. Open Command Prompt as Administrator
2. Type: sfc /scannow
3. Wait for the process to complete and restart your PC. 

I hope this helps. 

Take care and have a good day.
