OmniBook represents a series of laptop computers initially developed by Hewlett-Packard and presently offered by its successor, HP Inc.. Debuting in 1993 as laptops and notebooks tailored for business users, the brand remained active until 2002.
In 2024, HP Inc. revived the OmniBook label within its broader Omni brand strategy, merging its consumer laptop categories—including HP Spectre, HP Envy, HP Pavilion, and HP Essential—into a single portfolio. This reintroduction highlights AI-driven hardware and software capabilities, reflecting HP's objective to become a leader in the advancing AI-powered PC sector.
History
The OmniBook line was introduced in 1993, replacing the HP Vectra LS series as Hewlett-Packard’s primary business laptop offering. Following HP’s 2002 acquisition of Compaq, the OmniBook series was phased out in favor of models such as Compaq Presario, HP Compaq, and HP Pavilion.
In 2024, HP Inc. consolidated its consumer PC products under the new Omni brand: OmniBook for laptops, OmniDesk for desktops, and OmniStudio for all-in-one systems. This rebranding retired legacy names like Pavilion and placed emphasis on embedding AI across all devices. The comeback of the OmniBook name signaled a return to a historic brand identity with a focus on cutting-edge AI computing technologies.
Models
The original OmniBook lineup (1993–2002) included a range of business notebooks and laptops available in various sizes and specifications. It covered multiple generations of Intel and AMD processors, from the first-generation Pentium through to the Pentium 4, also encompassing some models powered by 386, i486, and Celeron CPUs. Early to mid-1990s versions occasionally featured a right-side pop-up mouse.
Since 2024, the OmniBook collection is divided into five tiers: 3, 5, 7, X, and Ultra—where Ultra represents the top-tier model and 3 serves as the entry-level option. This classification is consistent across other HP Omni products like OmniStudio and OmniDesk. As of mid-2025, the X model runs on Qualcomm Snapdragon processors (Snapdragon X), while the 5, 7, and Ultra variants utilize either AMD Ryzen or Intel Core Ultra CPUs; the 3 model is exclusively equipped with AMD Ryzen chips. Every current model integrates AI functionality with dedicated neural processing units (NPUs) to accelerate AI tasks and comes preloaded with Microsoft's Copilot chatbot on Windows.

OmniBook 300
Launched in June 1993, the HP OmniBook 300 (OB300) was among the pioneering subnotebooks in HP’s OmniBook lineup. 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 distinctive pop-up computer mouse mechanism—later incorporated into the OmniBook 800CT model—alongside a 9-inch VGA display. It featured dual PCMCIA slots, allowing expansion with memory, modem, network cards, or other peripherals. Storage configurations were offered in three variants: no internal mass storage (F1030A at ), a 10 MB flash memory disk (F1031A at ), or a 40 MB hard drive (F1032A at ). The flash memory version provided advantages in weight reduction and extended battery endurance compared to the hard drive model. A key innovation was its “Instant On” capability.
Operating on streamlined versions of MS-DOS 5.0 and Windows 3.1, the OmniBook 300 came with Microsoft Excel and Microsoft Word embedded directly in ROM—a rare approach even by today’s standards due to storage limitations. The “International English” edition utilized code page 850 as its hardware code page.
OmniBook X
Introduced in May 2024 as the inaugural entry of the modern OmniBook series, the HP OmniBook X (14-fe000) is designed as a cutting-edge AI-enhanced laptop. It weighs roughly 2.97 pounds and has dimensions of 12.32 × 8.8 × 0.56 inches at the front, increasing slightly to 0.57 inches at the rear. This model is powered by a Qualcomm Snapdragon X Elite processor featuring an integrated NPU dedicated to AI acceleration, complemented by a Qualcomm Adreno GPU. The display is a 14" OLED IPS touchscreen offering a resolution of 2240 × 1400 pixels. Memory options include either 16 GB or 32 GB RAM, paired with solid-state drives ranging from 512 GB up to 2 TB. Connectivity is robust with an integrated 5MP webcam and support for Qualcomm Wi-Fi 6E or Wi-Fi 7. Battery performance is estimated at approximately 26 hours.
Preloaded with Windows 11, the OmniBook X incorporates Microsoft's Copilot AI assistant, Windows Studio Effects for enhanced media experiences, and Poly Studio audio optimization. It is marketed under Microsoft’s Copilot+ PC platform branding and features a dedicated Copilot key on the keyboard that replaces the conventional menu key.
