Inspiron keyboard problem with 7559

I am facing problem with keyboard of 2.5 year old Dell Inspiron 7559 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 remove battery and resetting by holding the power 15 seconds, updating the bios, remove and place keyboard again. I also found out that if that happens, if I hold space key and type, then the keys are written and function correctly. I saw that there are so many keyboard issues with driver. I also try that one but it does not work. What would be the cause?

I believe I found a solution. I am writing so that somebody can have the same issue.

Currently, there is no problem. However, not sure if it will have occurred in the future. 

First, I tried driver update, driver uninstall and install for the keyboard. It does not solve the problem. 

Second, I reinstall BIOS. It did not solve the problem.

Third, I did the hard reset by removing the battery and holding 15 seconds to the power button. It did not solve the problem. 

Fourth,  I did the hard reset by draining the battery and plugin as suggested, but it did not work. 

Fifth, I update, reinstall the touchpad driver. It did not solve the problem.

Finally, I downgrade the BIOS from 1.2.9 to 1.2.7 and currently, it seems that it is worked. Not sure how long it will continue.  

(I have tried touch screen and it was working fine before trying all. I have not tried the external keyboard as suggested in many posts before trying all other options since the keyboard functions correctly if I hold space key as explained in the first message.)

That driver is a Microsoft Windows driver and automatically installed. A system reset does not seem to be more than a temporary fix and at times does not affect the problem at all. The only fix I have seen that seemed to work was to let the battery drain down completely. Once the battery was 100% drained the user plugged in the adapter and from that point on the keyboard worked properly. You might try that.
