OmniBook represents a series of laptop computers initially developed by Hewlett-Packard and now promoted by its successor, HP Inc.. Debuting in 1993 as laptops and notebooks targeted at business users, the brand remained active until 2002.
In 2024, HP Inc. revived the OmniBook name within its new Omni lineup, which unifies consumer laptop ranges such as HP Spectre, HP Envy, HP Pavilion, and HP Essential. This relaunch establishes OmniBook as HP’s premier consumer laptop brand, emphasizing cutting-edge computing enhanced by integrated artificial intelligence across both hardware and software platforms.
History
Introduced in 1993, OmniBook replaced the HP Vectra LS series as Hewlett-Packard’s dedicated business laptop offering. Following HP’s 2002 acquisition of Compaq, the OmniBook series was phased out, giving way to the Compaq Presario, HP Compaq, and HP Pavilion product lines.
In 2024, HP Inc. consolidated its consumer PC portfolio under the Omni brand umbrella: OmniBook for laptops, OmniDesk for desktop systems, and OmniStudio for all-in-one devices. This rebranding strategy retired the long-standing Pavilion name and aligned with HP’s vision of AI-powered personal computers designed to deliver superior performance and user experience. The reinstated OmniBook brand draws on its historical prestige while spotlighting AI integration tailored to contemporary business and consumer needs.
Models
The original OmniBook range (1993–2002) encompassed various business notebooks and laptops available in diverse sizes and configurations. These devices utilized generations of Intel processors and occasionally AMD chips, spanning from the initial Pentium through to the Pentium 4, with some early units employing 386, i486, and Celeron CPUs. Certain models from the early to mid-1990s featured a small pop-up pointing device located on the right side.
From 2024 onward, the OmniBook lineup is organized into five tiers: 3, 5, 7, X, and Ultra—where Ultra signifies the top-tier model and 3 represents entry-level offerings. Complementary HP products within the Omni family (OmniStudio and OmniDesk) follow a similar classification scheme. As of mid-2025, the X model is equipped with Qualcomm Snapdragon processors (Snapdragon X), while models 5, 7, and Ultra incorporate either AMD Ryzen or Intel Core Ultra CPUs. The 3 series exclusively utilizes AMD Ryzen processors. All current models within OmniBook, OmniDesk, and OmniStudio integrate AI capabilities via dedicated neural processing units (NPUs) and come preloaded with Microsoft's Copilot chatbot software on Windows.

OmniBook 300
Released in June 1993, the HP OmniBook 300 (OB300) represents an early entry in HP’s OmniBook series of subnotebooks. Weighing just 2.9 pounds and measuring 1.4 × 6.4 × 11.1 inches, it was equipped with an AMD 386SX-LV CPU, a full-sized keyboard, a pop-up computer mouse, and a 9-inch VGA display. The device offered two PCMCIA slots to accommodate memory expansions, modem cards, network adapters, or other peripherals. Storage configurations included no mass storage (F1030A at ), a 10 MB flash memory drive (F1031A at ), or a 40 MB hard drive (F1032A at ). The flash memory variant provided advantages in weight reduction and extended battery life over the hard disk model. Among its key innovations was the “Instant On” feature.
The OmniBook 300 came preloaded with streamlined versions of MS-DOS 5.0 and Windows 3.1. Due to constrained storage capacity, both Microsoft Excel and Microsoft Word were stored in ROM—a practice still uncommon today. The “International English” edition utilized code page 850 as its hardware code page.
OmniBook X
Announced in May 2024, the HP OmniBook X (14-fe000) is the newest addition to the OmniBook lineup and marks HP’s first AI-enabled personal computer. It weighs around 2.97 pounds and has dimensions of 12.32 × 8.8 × 0.56–0.57 inches. This model is powered by a Qualcomm Snapdragon X Elite processor featuring a dedicated NPU for AI tasks alongside a Qualcomm Adreno GPU. The laptop boasts a 14" OLED IPS touchscreen with a resolution of 2240 × 1400 pixels, with memory options of either 16 GB or 32 GB, and SSD capacities of 512 GB, 1 TB, or 2 TB.
Additional specifications include an integrated 5MP webcam and support for Qualcomm Wi-Fi 6E or Wi-Fi 7 wireless standards. Battery endurance is estimated at approximately 26 hours.
Pre-installed with Windows 11, the OmniBook X incorporates Microsoft’s Copilot AI assistant, Windows Studio Effects, and Poly Studio audio enhancements. It aligns with Microsoft’s Copilot+ PC platform branding and introduces a dedicated Copilot key on the keyboard that replaces the conventional menu key.
