OmniBook represents a series of laptop computers initially developed by Hewlett-Packard and now promoted by its successor entity, HP Inc.. Debuting in 1993 as laptops tailored for business use, the brand remained active until its discontinuation in 2002.

In 2024, HP Inc. revived the OmniBook name within its Omni product range, supplanting earlier consumer lines such as HP Spectre, HP Envy, HP Pavilion, and HP Essential. This relaunch establishes OmniBook as HP’s premier consumer laptop series, incorporating cutting-edge artificial intelligence capabilities in both hardware and software, aligning with the advancing AI-driven PC market.

History

The OmniBook brand was introduced in 1993, taking over from the HP Vectra LS series as Hewlett-Packard’s dedicated business laptop line. The brand ceased production in 2002 following HP’s acquisition of Compaq, which shifted focus toward the Compaq Presario, HP Compaq, and HP Pavilion product families.

In 2024, HP Inc. consolidated its consumer PC offerings under the new Omni branding: OmniBook for laptops, OmniDesk for desktops, and OmniStudio for all-in-one systems. This approach merges several legacy lines into a unified AI-centric platform crafted for future computing demands, marking the return of the OmniBook label after a 22-year absence.

Models

The original OmniBook range (1993–2002) consisted of various business notebooks and laptops available in multiple sizes and configurations. These devices employed several generations of Intel processors and occasionally AMD chips, spanning from the first-generation Pentium through to the Pentium 4, including some models powered by 386, i486, and Celeron CPUs. Early iterations were notable for featuring a distinctive pop-up mouse located on the right side.

The revived OmniBook lineup (from 2024 onward) is categorized into five tiers: 3, 5, 7, X, and Ultra — with Ultra representing the top-tier option and 3 serving as the entry-level model. This grading system is consistent across other HP Omni products like OmniStudio and OmniDesk. By mid-2025, the X model is equipped with Qualcomm Snapdragon processors (Snapdragon X), while the 5, 7, and Ultra models utilize either AMD Ryzen or Intel Core Ultra CPUs; the 3 model exclusively features AMD Ryzen processors. Each model integrates AI capabilities supported by dedicated neural processing units (NPUs) to enhance AI workloads and comes preloaded with Microsoft's Copilot assistant software on Windows.

OmniBook 300

Introduced in June 1993, the HP OmniBook 300 (OB300) represented an early entry in the OmniBook subnotebook lineup. Weighing a mere 2.9 pounds and with dimensions of 1.4 × 6.4 × 11.1 inches, it was equipped with an AMD 386SX-LV CPU, accompanied by a full-sized keyboard, a pop-up mouse, and a 9-inch VGA display. The system provided two PCMCIA slots to accommodate memory expansions, modem cards, network adapters, or other peripherals. Storage configurations varied: the F1030A model came without mass storage at a price of US$1515; the F1031A included a 10 MB flash memory disk costing US$2375; and the F1032A offered a 40 MB hard drive priced at US$1950. Opting for flash memory resulted in lower weight and extended battery longevity compared to the hard drive alternative. A standout feature was its “Instant On” capability.

The device was shipped with streamlined editions of MS-DOS 5.0 and Windows 3.1. Due to constrained storage capacity, both Microsoft Excel and Microsoft Word were embedded directly into ROM—a practice rare even today. The “International English” variant utilized code page 850 rather than the more commonly used code page 437.

OmniBook X

Announced in May 2024, the HP OmniBook X (14-fe000) represents the latest evolution in the OmniBook series as an AI-enhanced laptop. It weighs about 2.97 pounds and measures approximately 12.32 × 8.8 × 0.56 inches at the front tapering to 0.57 inches at the rear. Powered by a Qualcomm Snapdragon X Elite processor featuring a dedicated NPU for AI acceleration, it incorporates a Qualcomm Adreno GPU alongside a 14" OLED IPS touchscreen panel with a resolution of 2240 × 1400 pixels. Memory options include either 16 GB or 32 GB paired with solid-state drives of 512 GB, 1 TB, or 2 TB capacity. Connectivity features consist of an integrated 5MP webcam and support for Qualcomm Wi-Fi 6E or Wi-Fi 7. Battery endurance is estimated at roughly 26 hours.

Preloaded with Windows 11, the OmniBook X integrates Microsoft's Copilot AI assistant, Windows Studio Effects, and Poly Studio audio enhancements. It adheres to Microsoft's Copilot+ PC platform branding and introduces a dedicated Copilot key on the keyboard that replaces the traditional menu key.
