Bob Johnson's Computer Stuff Refurbished Rugged Laptop Warranty

We back every purchase of our rugged laptops with our non-transferable Limited Lifetime Warranty, which provides automatic and free coverage for the first six months that you own your laptop. You also have the option to upgrade this warranty with one of our extended warranty options. These options include:

  • One-Year Extended Warranty
  • Two-Year Extended Warranty
  • Three-Year Extended Warranty

  • If you purchase one of these extended warranty options, it gets added to the Limited Lifetime Warranty. So, if you buy the One-Year, technically, you get a year and a half.

    And with the Three-Year extended warranty, if you trade your laptop back in, you get a $150 in-store credit toward your next rugged laptop!

    You can see more about these purchase options in the upgrade option list to the right. For any other questions that you may have, you can refer to our warranty page or call our office at 302-659-2727.
