OmniBook represents a series of laptop computers initially developed by Hewlett-Packard and now offered by its successor, HP Inc.. First launched in 1993 targeting business users, the brand remained active until 2002.
In 2024, HP Inc. revived the OmniBook brand within its new Omni lineup, which replaced earlier consumer ranges such as Spectre, Envy, Pavilion, and Essential. The modern OmniBook series centers on consumer laptops equipped with integrated artificial intelligence capabilities in both hardware and software, positioning the brand at the forefront of the developing AI PC market.
History
Introduced in 1993, OmniBook replaced the HP Vectra LS as Hewlett-Packard’s primary business laptop offering. Following HP’s acquisition of Compaq in 2002, the OmniBook line was phased out in favor of the Compaq Presario, HP Compaq, and HP Pavilion product families.
In 2024, HP Inc. unified its consumer PC portfolio under the new Omni brand umbrella: OmniBook for laptops, OmniDesk for desktop systems, and OmniStudio for all-in-one devices. This rebranding highlights AI-driven computing features aligned with emerging trends in next-generation PCs. The return of the OmniBook name signifies a comeback of a legacy brand after being dormant for 22 years.
Models
The original OmniBook series (1993–2002) included a range of business notebooks and laptops available in various sizes and configurations. It encompassed multiple generations of Intel processors and occasionally used AMD CPUs, spanning from the original Pentium through to the Pentium 4, as well as some models featuring 386, i486, and Celeron chips. Early versions were notable for a distinctive pop-up mouse located on the right side.
Since its 2024 relaunch, the OmniBook brand has introduced models organized into five tiers: 3, 5, 7, X, and Ultra—with Ultra representing the highest-end option and 3 serving as entry-level. Other HP products under the Omni umbrella such as OmniStudio and OmniDesk also follow this classification system. As of mid-2025, the X model is powered by Qualcomm Snapdragon processors (Snapdragon X), whereas models 5, 7, and Ultra utilize either AMD Ryzen or Intel Core Ultra CPUs; the 3 model exclusively runs on AMD Ryzen processors. Every current OmniBook device integrates AI-optimized processors featuring dedicated neural processing units (NPUs) to enhance AI task performance and includes Microsoft's AI assistant Copilot embedded within Windows.

OmniBook 300
The HP OmniBook 300 (OB300), released in June 1993, was among the pioneering models in the OmniBook series of subnotebook computers. It weighed a mere 2.9 pounds and measured 1.4 × 6.4 × 11.1 inches. The device was equipped with an AMD 386SX-LV processor, a full-sized keyboard, and a pop-up computer mouse, a feature later adopted in the OmniBook 800CT. The display was a 9-inch VGA screen, and it offered two PCMCIA slots for expansion options such as memory cards, modems, or network adapters. Storage variants included no built-in mass storage (F1030A), a 10 MB flash memory disk (F1031A), or a 40 MB hard drive (F1032A). The flash memory model provided advantages in weight reduction and battery longevity compared to the hard drive version. Among its standout features was the “Instant On” capability.
Preloaded software consisted of streamlined editions of MS-DOS 5.0 and Windows 3.1. Due to limited storage capacity, the system incorporated embedded versions of Microsoft Excel and Microsoft Word within ROM, an uncommon approach at that time. The “International English” variant used code page 850 rather than the more typical code page 437 hardware code page.
OmniBook X
The HP OmniBook X (14-fe000), unveiled in May 2024, serves as the flagship model in HP’s latest OmniBook lineup, embodying the company’s vision for AI-enhanced computing. Weighing approximately 2.97 pounds, its dimensions are 12.32 × 8.8 × 0.56 inches at the front and 12.32 × 8.8 × 0.57 inches at the rear. This model is powered by a Qualcomm Snapdragon X Elite processor featuring an integrated Neural Processing Unit (NPU) designed for AI acceleration. Graphics are handled by a Qualcomm Adreno GPU, and it sports a 14-inch OLED IPS touchscreen with a resolution of 2240 × 1400 pixels. Memory options include either 16 GB or 32 GB, paired with SSD storage capacities ranging from 512 GB up to 2 TB. Connectivity features encompass an integrated 5MP webcam and support for Qualcomm Wi-Fi 6E or Wi-Fi 7 wireless standards. The battery life is estimated at roughly 26 hours.
Running on 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 standards and introduces a dedicated Copilot key on the keyboard, replacing the traditional menu key found on earlier models.
