The HP ProBook is a line of business-oriented laptop computers made by Hewlett-Packard. HP marketed the ProBook series to business users; the list price was lower than that of HP's higher-end EliteBook series.

HP EliteBook is a line of business-oriented high-end laptops and previously mobile workstations made by Hewlett-Packard. The EliteBook series, which fits above the small business ProBook series, was introduced in August 2008 as a replacement of the HP Compaq high end line of business laptops. The EliteBook brand included mobile workstations until September 2013, when they were rebranded as HP ZBook. The EliteBook mainly competes against computer lineups such as Acer's TravelMate, Dell's Latitude, Lenovo's ThinkPad and Toshiba's Portégé and Tecra.
