i had the same problem as so many others...a 1 and nearby keys work sometimes and sometimes they don't . Verified answer is that there is a problem on the motherboard keyboard connector(a hardware issue, and that person said they would never buy from Dell again. The answers from Dell were to troubleshoot BIOS and firmware, which are totally unrelated and do not solve the problem.
I think "never buy from Dell again" was a great answer...since that discussion thread was closed and that was part of the verified answer!!!! Dell did nothing to address this problem that so many people had. I called Dell and was asked to pay about $200 for a new keyboard since my Inspiron 11 was out of warranty, But wow, I only used this product a few times...It was like new!!!! I used this product only a few times after i bought it,
When so many people had the exact same problem, this is a product quality issue... I can't believe that Dell does not look for problems like this in the discussion threads and make it right! If Dell wants to help... let me know!
