laptop keyboard not working on inspiron 15 3000 series
laptop keyboard not working on inspiron 15 3000 series. I tried reinstalling device software but after installation keyboard still not working. Connected external key board and am able to use it. Device manager shows: Ran diagnostic from dell website, and it says hardware failure. Any suggestions/ideas.

First step would be to replace the keyboard with a new one -- if that doesn't solve the issue, the problem is with the keyboard controller (which means a replacement mainboard is required).
