Hi
I am facing problem with keyboard of 1.5 year old Dell Inspiron i7559 laptop. Few days back, the keyboard suddenly stopped responding while I was using Google Chrome , and volume display kept popping up randomly. I restarted the laptop but no key press was being responded with character "nb" automatically getting typed. With multiple efforts, I was able to input PIN through touch keyboard. I diagnosed with Dell diagnosis tool but all the component passed test. Then for sometime, the laptop responded normally. But this problem kept on recurring intermittently. I tried changing keyboard. It worked well for 3-4 days but then suddenly all keys stopped responding. So I concluded that keyboard was not faulty. and I put the original keyboard into the system. Then I tried following method as suggested in an old post by Ravi CH of Dell.

Hi DS15,
I’d suggest that you follow the steps mentioned below and check for issue resolution.
- Switch off the computer.
- Disconnect the AC adapter from the system.
- Remove the battery from the computer.
- Press and hold down the power button for 15 seconds.
- Then connect back all the peripherals and check for issue resolution.
Also, I would suggest that you run the diagnostics on the computer after the above steps by following the steps mentioned in the video below and check if there is any issue with the hardware on your system.

With this the problem was solved. The laptop and keyboard were responding normally. However the joy lasted only for 2 days.
Yesterday while using Google Chrome, again Volume display popped up and keyboard stopped responding with characters "nb" randomly appearing.
Do I need to again do the battery removal process as suggested above frequently or could there be a permanent solution? Also would love to know the root cause of the problem.
