OmniBook represents a series of laptop computers originally manufactured by Hewlett-Packard and now promoted by its successor, HP Inc.. Debuting in 1993 as a collection of business-focused laptops and notebooks, the OmniBook line was produced until 2002.
In 2024, HP Inc. revived the OmniBook brand within its newly launched Omni series, which supplanted the earlier Spectre, Envy, Pavilion, and Essential product lines. This reintroduction establishes OmniBook as HP’s premier consumer laptop range, incorporating built-in artificial intelligence features in both hardware and software, catering to the growing AI PC segment.
History
The OmniBook line was introduced in 1993 as Hewlett-Packard’s successor to the HP Vectra LS models for business laptops. Production ceased in 2002 following HP’s acquisition of Compaq, which led to a strategic shift towards the Compaq Presario, HP Compaq, and HP Pavilion product families.
In 2024, HP Inc. streamlined its consumer PC offerings under the new Omni umbrella: OmniBook for laptops, OmniDesk for desktops, and OmniStudio for all-in-one systems. This initiative replaced the longstanding Pavilion brand and highlighted AI-driven computing capabilities designed for future demands. The comeback of the OmniBook name signifies a return to HP’s heritage branding with an emphasis on AI-enhanced consumer laptops after a two-decade absence.
Models
The initial OmniBook lineup (1993–2002) included various business notebooks and laptops available in multiple sizes and specifications. It supported a variety of Intel processors and occasionally AMD chips, ranging from early Pentium CPUs to the Pentium 4, along with some models featuring i386, i486, and Celeron processors. Certain early-to-mid 1990s models were notable for including a small pop-up mouse located on the right side.
Since its 2024 relaunch, the OmniBook series is segmented into five tiers: 3, 5, 7, X, and Ultra—where Ultra represents the top-tier model while 3 serves as the entry-level option. This classification system is also applied across other HP Omni products such as OmniStudio and OmniDesk. By mid-2025, X series models are powered by Qualcomm Snapdragon processors (Snapdragon X), whereas the 5, 7, and Ultra variants utilize either AMD Ryzen or Intel Core Ultra CPUs; the 3 series exclusively employs AMD Ryzen chips. All current models within OmniBook, OmniDesk, and OmniStudio incorporate AI capabilities through dedicated neural processing units (NPUs) to enhance AI workloads and come preloaded with Microsoft's Copilot chatbot on Windows.

OmniBook 300
Introduced in June 1993, the HP OmniBook 300 (OB300) was among the earliest models in the OmniBook series, classified as a subnotebook. It weighed 2.9 pounds and measured 1.4 × 6.4 × 11.1 inches. The device was powered by an AMD 386SX-LV processor and included a full-sized keyboard along with a pop-up mouse, a design later incorporated into the OmniBook 800CT. Its display was a 9-inch VGA screen, and it supported two PCMCIA slots for expansion cards such as memory, modem, or network adapters. Storage configurations varied: the F1030A model came without mass storage priced at US$1515; the F1031A featured a 10 MB flash memory disk costing US$2375; and the F1032A offered a 40 MB hard drive option at US$1950. The flash memory version was lighter and provided longer battery life compared to the hard drive variant. A key innovation was its “Instant On” capability.
Operating on a streamlined version of MS-DOS 5.0 and Windows 3.1, the OmniBook 300 had limited storage capacity, leading to Microsoft Excel and Word being embedded directly in ROM—a rare approach even by today’s standards. The “International English” edition utilized code page 850 rather than the more common code page 437.
OmniBook X
Announced in May 2024, the HP OmniBook X (14-fe000) marks the newest iteration in the OmniBook lineup, distinguished by its AI-enhanced features. It weighs roughly 2.97 pounds and measures 12.32 × 8.8 × 0.56 inches at the front, tapering to 0.57 inches at the rear. The laptop is equipped with a Qualcomm Snapdragon X Elite processor featuring a dedicated Neural Processing Unit (NPU) for AI tasks and an Adreno GPU for graphics performance. It sports a 14-inch OLED IPS touchscreen with a resolution of 2240 × 1400 pixels, with memory options of either 16 GB or 32 GB and SSD storage capacities ranging from 512 GB up to 2 TB. Additional hardware includes an integrated 5MP webcam and wireless connectivity supporting Qualcomm Wi-Fi 6E or Wi-Fi 7 standards. Battery endurance is rated at approximately 26 hours.
The OmniBook X comes preloaded with Windows 11 and incorporates Microsoft’s Copilot AI assistant, Windows Studio Effects for enhanced media experiences, and Poly Studio audio optimization. It aligns with Microsoft’s Copilot+ PC platform branding and introduces a dedicated Copilot key on the keyboard that replaces the traditional menu key.
