OmniBook refers to a series of laptop computers initially developed by Hewlett-Packard and presently sold under its successor, HP Inc.. Debuting in 1993 as laptops tailored for business professionals, the OmniBook range continued production until 2002.

In 2024, HP Inc. revived the OmniBook brand as part of its newly introduced Omni product family, which supplanted the earlier Spectre, Envy, Pavilion, and Essential series. This repositioning established OmniBook as HP’s flagship consumer laptop line, incorporating built-in artificial intelligence capabilities within both hardware and software to address the evolving needs of future computing.

History

The OmniBook line was launched in 1993 to succeed the HP Vectra LS models, focusing on compact laptops and subnotebooks designed for business users. Production ceased in 2002 after HP acquired Compaq, which redirected attention toward the Compaq Presario, HP Compaq, and HP Pavilion product lines.

In 2024, HP Inc. reorganized its consumer PC offerings under the Omni brand umbrella: OmniBook for laptops, OmniDesk for desktop computers, and OmniStudio for all-in-one devices. This strategic overhaul retired legacy brands such as Pavilion to highlight AI-driven computing solutions. The reintroduced OmniBook now symbolizes HP’s AI-enhanced consumer laptop range, marking its return after a 22-year absence.

Models

The original OmniBook collection (1993–2002) encompassed diverse business-oriented notebooks and laptops available in various sizes and specifications. It featured processors primarily from Intel, with some models utilizing AMD chips, ranging from the early Pentium series up to the Pentium 4, including certain units equipped with 386, i486, and Celeron CPUs. Some early to mid-1990s models incorporated a distinctive pop-up mouse positioned on the right side.

The modern OmniBook lineup introduced in 2024 consists of five tiers: 3, 5, 7, X, and Ultra—with Ultra representing the top-tier model and 3 serving as the entry-level option. Other HP products such as OmniStudio and OmniDesk adopt this same 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; model 3 is exclusively equipped with AMD Ryzen processors. Every current OmniBook device incorporates AI-optimized processors featuring dedicated neural processing units (NPUs) and comes preloaded with Microsoft's Copilot chatbot software running 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 equipped with an AMD 386SX-LV CPU, a full-sized keyboard, and a pop-up mouse design that was later incorporated into the OmniBook 800CT. Its display consisted of a 9-inch VGA screen. The unit featured two PCMCIA slots supporting memory expansion, modem, network adapters, or other peripherals. Storage configurations varied: the F1030A model lacked mass storage (), the F1031A included a 10 MB flash memory drive, and the F1032A came with a 40 MB hard drive. Opting for the flash memory version offered reduced weight and longer battery endurance compared to the hard disk alternative. A key highlight was its “Instant On” capability.

Operating on streamlined editions of MS-DOS 5.0 and Windows 3.1, the OmniBook 300 faced storage limitations that led to an unusual approach: both Microsoft Excel and Microsoft Word were embedded in ROM, a practice still rare today. The “International English” variant utilized code page 850 rather than the more typical code page 437 hardware code page.

OmniBook X

Announced in May 2024, the HP OmniBook X (14-fe000) represents the newest iteration in the OmniBook lineup, designed as an AI-enhanced laptop. It weighs about 2.97 pounds and measures 12.32 × 8.8 × 0.56 inches at the front, tapering to 0.57 inches at the rear. The system is powered by a Qualcomm Snapdragon X Elite processor featuring a dedicated NPU for AI acceleration alongside a Qualcomm Adreno GPU. Its display is a 14-inch OLED IPS touchscreen with a resolution of 2240 × 1400 pixels. Memory options include either 16 GB or 32 GB, while SSD storage ranges from 512 GB up to 2 TB. Connectivity features encompass an integrated 5MP webcam and wireless capabilities via Qualcomm Wi-Fi 6E or Wi-Fi 7 modules. Battery life is estimated at approximately 26 hours.

Preloaded with Windows 11, the OmniBook X incorporates Microsoft's Copilot AI assistant, Windows Studio Effects for enhanced audio-visual experience, and Poly Studio audio optimization. It adheres to Microsoft’s Copilot+ PC platform standards and introduces a dedicated Copilot key on its keyboard, replacing the traditional menu key found on earlier models.
