The Genius Bar is a technical support service provided by Apple Inc. inside Apple Stores to support the use of its products and services. The locations provide concierge-style, face-to-face support for customers from "Geniuses" who are specially trained and certified by Apple, with multiple levels of certification depending on the products serviced. Many of the services are provided for free, regardless of the product's warranty status. For problems that require repairs to hardware, most of the work can be completed on-site, while customers wait. The Genius Bar at Apple Stores offers same-day service for both OLED/LCD screen and lithium-ion battery replacement. If the in-house technician needs to send the affected device to an Apple Repair Center, most repaired or replaced iPhones will be returned or ready for pickup in approximately 3 business days. Ron Johnson, the former senior vice president for retail, often referred to the Genius Bar as the "heart and soul" of the Apple Store. Store layout The layout of a Genius Bar previously consisted of at least two 15" or 17" current Apple Portable Computers, often mounted on "floating" stands. Employees now use iPads with similar software to check in machines for repairs. There may be other "floating" notebooks for iPod/iPhone troubleshooting, often referred to as "floaters". LCD screens behind the Bar play looped videos which offer tips to customers waiting for help. Stools can be found in front of the Bar for people to sit and chat with each other or with employees. The "Red Telephone" sometimes seen behind the Genius Bar was a direct line to Apple product specialists, allowing for problems and questions too complicated for the in-store employees to answer. As of August 2009, this phone is no longer installed in newer Apple Retail Stores and removed in others. Staff The employees can also be viewed as the local representatives of AppleCare. They offer personal support when customers have problems or questions relating to their Apple products. Most services carried out at the Genius Bar are free. Non-warranty service (which is paid for by the customer when repairs are complete) is also routinely performed. In some countries, Apple has service depots where portable repairs (for issues such as accidental damage) can be completed for a flat rate. Most portable computer repairs and all desktop repairs are performed in-store and completed overnight or within a few days. In September 2009, the Family Room Specialists
