Can't tell you about the warranty, but DEFINITELY NO USER GUIDE. You're on you're own. I paid $100 to have my info transferred from old computer to new, and they tried to make it as much as possible like Windows 7, with start buttons, etc. Still getting used to and trying to find old programs I had. I'm a chef and love to cook: over 400 recipes. Took a long time to find them (under "recent places") but unable to access them. Error messages, or some strange code. Guess we will be going back to computer shop to see if they can solve.
To be honest I didnt even look at the warranty before I bought it. I have had several computers and all have lasted past the original warranty before any problems arose. I searched Dell on this laptop and it told me I that its in warranty until 12-31-2014 and if I renew it before then it will continue on. As far as a user manual goes, I believe it had a basic tutorial at the beginning but I skipped over it. Sorry I could not be of more help.
For question two, the answer is a definite NO, no user guide, no instructions, no nothing. Unless you happen to be familiar with Windows 8, stay away fro purchasing one. Microsoft may think that their system is intuitive, but, I have owned many computer, starting with Commodore DOS units, Microsoft
