I think this flag was declined because the moderator saw the following text in the user's answer...
On going into BIOS and checking the boot sequence I found that the Kindle had become the 1st boot device, and of course the PC couldn't boot from a Kindle! Changed the boot order back to the main hard drive and it booted-up as normal, with the Kindle still connected.
... and thought that, because the user provides a solution that worked for them (even if this is not the best / most accurate solution, and even if it doesn't work for the OP), this is not "Not An Answer".
I would tend to agree.
However, if you have specific experience in this area and you believe that the solution the user proposed is unlikely to help the OP in any way, you can register your assessment by simply downvoting the post and leaving a comment describing what is incorrect about the answer, or how it would fail to help the OP.
Based on my experience in this area, I think this answer is more likely to be correct, as the symptom observed by the OP was a clock reset, not a failure to boot. The guy who added the answer you linked to seems to have a separate issue about his computer trying to boot from an attached mobile device.
But since an answer was provided (even if it misses the mark), the most we can do is downvote. If it gets many downvotes, it'll likely be deleted.
