If your computer is still under the Staples' warranty, and that warranty covers specifically what is wrong with your laptop, then it should be Staples' responsibility to either pay for repairs to your laptop, or exchange it. If all is well with the warranty, and yet Staples does nothing to repair or replace your laptop, then contact Better Business Bureau and get them involved. If you are in the right with this, and Better Business Bureau has to get involved, then you can rest assured that Staples will uphold their warranty obligation.
