OmniBook represents a series of laptop computers initially developed by Hewlett-Packard and now offered by its successor, HP Inc.. Launched in 1993 with a focus on business users, the brand remained active until 2002.

In 2024, HP Inc. revived the OmniBook name as part of its broader Omni product line, supplanting former consumer series such as HP Spectre, HP Envy, HP Pavilion, and HP Essential. The renewed OmniBook range is aimed at consumers, featuring AI-enhanced hardware and software, and is positioned within the growing market of AI-enabled PCs.

History

Introduced in 1993, the OmniBook replaced the HP Vectra LS line as Hewlett-Packard’s dedicated business laptop series. Following HP’s acquisition of Compaq in 2002, the OmniBook was phased out in favor of models under Compaq Presario, HP Compaq, and HP Pavilion brands.

By 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 devices—retiring long-established names like Pavilion. This reorganization highlights a strategic focus on embedding AI capabilities throughout both hardware and software to address future computing needs.

After a 22-year absence, HP resurrected the OmniBook brand as a flagship line for AI-centric consumer laptops within its comprehensive AI PC initiative.

Models

The initial OmniBook series (1993–2002) comprised various business notebooks and laptops available in different sizes and configurations. These models utilized a spectrum of Intel and AMD processors—from early i386, i486, and Celeron CPUs to the original Pentium and later Pentium 4 processors. Certain early units featured an innovative pop-up mouse positioned on the right side.

Since its 2024 relaunch, the OmniBook lineup is organized into five tiers: 3, 5, 7, X, and Ultra—with Ultra representing the premium segment and 3 serving as the entry-level option. This classification system is consistent across other HP Omni products such as OmniStudio and OmniDesk. As of mid-2025, X models are powered by Qualcomm Snapdragon processors (Snapdragon X series), while the 5, 7, and Ultra categories utilize either AMD Ryzen or Intel Core Ultra chips; the 3 series relies solely on AMD Ryzen processors. Every current model in the OmniBook, OmniDesk, and OmniStudio families incorporates AI capabilities through dedicated neural processing units (NPUs) designed to enhance AI workloads and includes Microsoft's Copilot chatbot integrated within Windows.

OmniBook 300

The HP OmniBook 300 (OB300) represents an early entry in the OmniBook series, debuting in June 1993 as a compact subnotebook. Weighing merely 2.9 pounds and measuring 1.4 × 6.4 × 11.1 inches, it was powered by an AMD 386SX-LV processor. The device featured a full-sized keyboard, a retractable computer mouse—a design element later incorporated into the OmniBook 800CT—and a 9-inch VGA display. Two PCMCIA slots allowed for expansion with memory, modem, or network cards. Storage configurations varied: the F1030A model lacked mass storage (), the F1031A included a 10 MB flash memory drive (), and the F1032A offered a 40 MB hard drive (). The flash memory edition provided advantages in weight reduction and extended battery duration compared to its hard drive counterpart. A key innovation was its “Instant On” capability.

Shipping with simplified versions of MS-DOS 5.0 and Windows 3.1, the OmniBook 300 also incorporated Microsoft Excel and Microsoft Word directly into ROM due to limited storage capacity—an uncommon approach at that time. The “International English” variant employed code page 850 as its hardware code page rather than the more typical code page 437.

OmniBook X

Unveiled in May 2024, the HP OmniBook X (14-fe000) marks the inaugural model of the latest OmniBook generation. Positioned as an advanced AI-enhanced laptop, it weighs approximately 2.97 pounds and measures roughly 12.32 × 8.8 × 0.56 inches at the front, tapering to 0.57 inches at the rear. It is equipped with a Qualcomm Snapdragon X Elite processor featuring an integrated NPU dedicated to AI acceleration and pairs with a Qualcomm Adreno GPU. The system boasts a 14-inch OLED IPS touchscreen panel with a resolution of 2240 × 1400 pixels, alongside options for either 16 GB or 32 GB of RAM and storage capacities reaching up to a 2 TB solid-state drive. Additional features include a built-in 5MP webcam and support for Qualcomm’s Wi-Fi 6E or Wi-Fi 7. Battery longevity is estimated at around 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 standards and introduces a dedicated Copilot key on the keyboard that replaces the conventional menu key.
