Overview
HP ProBook is a family of business-oriented laptop computers introduced by Hewlett-Packard in 2009 and subsequently sold by HP Inc. after the 2015 separation of HP's personal-systems and enterprise businesses. The line was created to occupy a practical middle and entry segment of HP's commercial notebook portfolio: it generally offered business features and serviceability at a lower list-price position than the company's EliteBook family. ProBook therefore served organizations that needed standardized Windows notebooks, employee productivity hardware, and basic enterprise manageability without purchasing HP's highest-end commercial systems. The first ProBook products appeared in April 2009 in the S-series. These initial notebooks covered several display sizes and processor platforms, including Intel-based 4410s, 4510s, and 4710s models and AMD-based 4415s and 4515s models. HP expanded the range with the 13.3-inch 4310s in June 2009. The S-series was revised in 2010 with Intel Core i3, i5, and i7 processors, aluminum exterior elements, chiclet keyboards, and multitouch ClickPads. Further design changes arrived in 2012, including a refreshed aluminum exterior. The series was discontinued after 2012. HP also introduced the B-series in October 2009 as a successor to the earlier HP Compaq B-series. Compared with the more consumer-like positioning of some S-series models, B-series machines emphasized conventional business usability and maintainability. Depending on configuration, they included optical-drive bays, docking connectors, pointing-stick options, display latches, drainage features, removable batteries, optional battery slices, trusted-platform modules, socketed processors, WLAN choices, and two memory slots. The B-series used both Intel and AMD processors and was updated through several generations before being discontinued in 2012. The compact M-series began with the ProBook 5310m in September 2009. It targeted users seeking a lighter, thinner business notebook and omitted an optical-drive bay. Its aluminum-and-magnesium enclosure weighed under four pounds and measured less than an inch thick. The 5320m followed in 2010, while the 5330m arrived in 2011 with a dual-tone aluminum chassis and Beats Audio branding. The M-series was discontinued in 2011. From 2013, HP reorganized the family around G-series generations. The G0 generation was followed by G1 in 2014 and subsequent generations identified as G2 through G10 in the reference material. The numbering convention generally indicated the class and screen size: models beginning with 4 were positioned as entry business systems, while 6-series models occupied a higher tier within ProBook; the second digit commonly corresponded to display dimensions, such as 13.3, 14.1, 15.6, or 17.3 inches. Additional suffixes could distinguish processor platforms, including AMD-based variants. G-series machines continued the use of aluminum and magnesium construction in relevant models and extended the range from entry-level to mid-class business notebooks. The ProBook portfolio has included compact, mainstream, and larger-screen notebooks across multiple generations. Its principal distinction within HP's lineup is a balance between commercial durability and affordability rather than the more extensive materials, security choices, and premium construction associated with EliteBook. The family competes with business and professional notebook lines such as Acer TravelMate and Extensa, ASUS ExpertBook, Dell Latitude and Vostro, Fujitsu LifeBook, Lenovo ThinkPad and ThinkBook, and Toshiba Portégé and Tecra. ProBook remains an HP commercial-PC brand, although exact model availability and specifications vary by market and generation.
History
HP ProBook began in 2009 as Hewlett-Packard's lower-priced commercial notebook family. At launch, HP maintained separate commercial naming structures: business desktops were associated with HP Compaq, while notebooks were introduced under the ProBook name. The first wave was the S-series, presented as standard or essential business notebooks. It included Intel and AMD configurations across 14-inch, 15.6-inch, 17.3-inch, and later 13.3-inch formats. This broad range allowed HP to address office users who needed conventional business notebooks at different sizes and price points. In September 2009, HP added the compact 5310m M-series. It was designed for mobility and used aluminum and magnesium while omitting an optical-drive bay. The model was followed by the 5320m in 2010 and 5330m in 2011. The latter added a dual-tone aluminum design and Beats Audio branding. The M-series was short-lived and ended in 2011. The B-series was announced in October 2009 as a replacement for the previous HP Compaq B-series. It represented a more traditionally business-focused branch of the early ProBook portfolio. The first AMD systems were the 6445b and 6545b, followed by Intel counterparts 6440b and 6540b. Subsequent revisions included 6450b, 6550b, 6455b, 6555b, 6460b, 6560b, 6465b, 6565b, 6470b, 6570b, and 6475b variants. The line emphasized features useful in organizational deployment and maintenance, including docking support, removable batteries, optional pointing sticks, TPM hardware, memory expansion, and, in many models, optical drives. B-series production ended in 2012. The S-series continued to evolve through models such as the 4230s, 4330s, 4430s, 4520s, 4530s, 4730s, 4340s, 4440s, 4540s, 4740s, and related AMD variants. Its 2010 update brought Intel Core i3, i5, and i7 processors, a brushed-aluminum case, a chiclet keyboard, and a multitouch ClickPad. A further exterior redesign was reported for 2012, after which the S-series was discontinued. Beginning in 2013, HP shifted the family to a G-series generation structure. The G0 generation was followed by G1 in 2014 and later generations through G10 in the supplied reference. The G-series introduced a clearer hierarchy in which 4-series systems were generally entry models and 6-series systems represented a higher ProBook class. Model-number conventions also commonly linked the second digit to screen size, while suffixes helped distinguish processor or platform variants. Across these generations, HP used aluminum and magnesium construction in relevant models and maintained both smaller and larger-screen configurations. The ProBook family has consequently developed from a set of separately named S-, B-, and M-series notebooks into a continuing generational commercial-PC platform. Its enduring role is to provide organizations with mainstream laptops combining business-oriented design, serviceability, and deployment features with a lower price position than EliteBook. HP ProBook is now associated with HP Inc.'s commercial personal-systems portfolio, while individual models and specifications differ across generations and geographic markets.
