Only items that have been purchased directly from HP.com, either through the HP Online Store or by phone can be returned. We can't accept returns or exchanges for items from the HP Parts Store, HP Technical Support, HP Retailers, HP Software or repairs.

(888) 650-1544 is the number I have for replacements at work, so I'm passing it on. Depending on where you purchased it from, their customer service may have a different phone number.
