Problem In Keyboard

I have inspiron N4050. Two of my laptop's key is not working properly, "left Arrow" key and "up arrow key" are not working, when I press any of these keys either some random key is entered in the OS or nothings happens. Particularly "mute key" is more often entered on pressing "left-arrow" key. Can anyone help with this.

Hi shantanu1993,

I suggest you to clean the keyboard with a can of compressed air to remove dust or any particles accumulated below the keys. You will also need to uninstall and reinstall the keyboard from the “Device Manager”. Please follow the steps provided below:

1. Click on “Start” and enter “Device Manager” without quotes in “Start Search” and press Enter.
2. Click on the arrow beside “Keyboards” and right click on the keyboard listed.
3. Click “Uninstall” and restart the computer. The keyboard would be installed automatically.

You may also try using an external keyboard and check if the issue occurs on it and let me know about your findings.

Nopes, still not working. I reinstalled my keyboard, blow compressed air on the board by vaccum cleaner and even in BIOS the keys are not working.
