“If it is not "Geek-Squad Certified", is it an external seller? How can we be assured the refurbished computer's quality? Some computers on this sight say they are "Geek-Squad Certified". I assume that means they were inspected and tested by the Geek Squad (possibly even refurbish by Geek Squad themselves). What about products that do not advertise this? Are they from an external seller? When buying refurbished computers I know it is important to know the quality of the refurbisher. How can I be assured the quality of this computer. What are return policies if something is broken?”
