OmniBook is a brand for a line of laptop computers produced by Hewlett-Packard from 1993 to 2002 and by its successor HP Inc. since 2024.
OmniBook originally began as a line of business-oriented laptops and notebooks produced by Hewlett-Packard between 1993 and 2002. After a 22-year hiatus, HP Inc., the successor company of the original Hewlett-Packard, reintroduced the brand name as part of the Omni brand of consumer-oriented computers in 2024, following a corporate restructuring of its product lines that year. It would coexist and gradually succeed the previous Spectre, Envy, Pavilion and Essential lines, effectively becoming a singular brand for all consumer-oriented laptops produced by the company.
The consumer-oriented OmniBook line, like the rest of the computers in the Omni series, is part of a computing platform known as AI PCs, designed for the next generation of computing. OmniBook laptops made since 2024 featured artificial intelligence technology integrated into the hardware and software.
In June 1993, Hewlett-Packard launched the OmniBook line of business-oriented laptops and subnotebooks. It succeeded the prior HP Vectra LS models of computers. Following the acquisition of Compaq in 2002, the OmniBook line was discontinued in favor of the Compaq Presario, HP Compaq, and HP Pavilion laptops.
In May 2024, HP (as HP Inc.) announced its intentions on restructuring their lineup of consumer PCs in preparation for the next generation of computers with artificial intelligence, stating that most of its PC models (except Omen) would adopt a new branding nomenclature under the new Omni brand, which consisted of the OmniBook, OmniStudio and OmniDesk models. It would coexist alongside the long-running Pavilion brand in use since 1995 among many other brands. The new Omni brand of computers would feature AI-powered hardware and software.
As part of the new Omni branding that year, HP repurposed the old OmniBook name that had been used for its former line of business-oriented laptops in the 1990s for a new line of next generation AI-powered laptops manufactured by HP, reviving the historic nameplate that had been absent for 22 years.
The original OmniBook line from 1993 to 2002 consisted of several different models of business notebooks and laptops produced in various sizes and configurations. Many generations of Intel (and sometimes AMD) processors were offered throughout the entirety of the original OmniBook brand, ranging from the original Pentium to the Pentium 4, with some models featuring 386, i486, and Celeron processors. Some OmniBook models from the early-to-mid 1990s also had a small pop-up mouse located on the right-hand side of the computer.
The current OmniBook line since 2024 consisted of various models grouped into five different grades from lowest to highest: 3, 5, 7, X, and Ultra; this format is also shared with the OmniDesk and OmniStudio lines as part of the Omni brand. , the 3 exclusively features AMD Ryzen processors, the 5, 7 and Ultra features AMD Ryzen or Intel Core Ultra processors, and the X features AMD Ryzen, Intel Core Ultra, or Qualcomm Snapdragon processors (specifically the Snapdragon X). Like many models in the Omni brand, all models of the current OmniBook line (as well as the OmniDesk and OmniStudio lines) featured processors with AI technology, dedicated neural processing units (NPUs) for accelerating AI applications and featured Microsoft's Copilot chatbot software as part of a standard installation of Windows.
