The EliteBook line was sold on its light weight and durability, but the ProBook range offers what HP refers to as a "business chic" design.
The new notebooks will sport case designs which aim to provide a "minimalist " look, offered in a "merlot" finish as well as several glossy designs.
Under the hood, the new ProBooks come with 14in, 15.6in and 17.4in screens, with the option of AMD or Intel processors on the two smaller models and Intel Core 2 Duo chips for the larger system.
Customers will also have the option of onboard or discrete graphic cards, and a choice of Wi-Fi or HP Gobi mobile broadband antennas. The machines come with Windows or SuSE Linux operating systems.
HP hopes that the new models will appeal to companies looking to marry low cost and style.
"It is not just about good looks or low cost," said Ted Clark, senior vice president of netbooks global business for HP. "The HP ProBooks deliver the right blend of features and professional innovations to provide a great user experience."
