Large-screen business laptop

The HP OmniBook 3 is a 17.3-inch Full HD IPS laptop built around the Intel Core Ultra 7 255U processor with 12 cores and integrated Intel Graphics. It ships with Windows 11 Home, 16GB of DDR5 memory running at 5600, and a combined 3TB of storage split between a 2TB internal SSD and a 1TB docking station. The Mica Silver chassis targets professionals who need a spacious display and ample capacity for documents and media.

Sustained multitasking performance

The 12-core Ultra 7 255U and its built-in AI engine are designed to maintain steady throughput during all-day workloads rather than short bursts. Sixteen gigabytes of DDR5 at 5600 keeps multiple applications responsive over long sessions, while the integrated graphics handle video calls and media playback without a discrete GPU. Wi-Fi 7 (802.11be) provides a stable wireless link for cloud-based workflows.

Build, ports and included dock

The laptop measures 15.65 by 10.09 by 0.65 inches and weighs 4.43 pounds, with a backlit keyboard and an FHD camera for low-light typing and conferencing. Connectivity includes two USB-A 3.0 ports, two USB-C 3.1 ports, HDMI 2.1 and a headphone/mic combo jack. The bundle adds a 7-in-1 docking station with 1TB of storage, a 32GB microSD card with adapter, a Type-C data cable, a 3-in-1 charging cable and a suede cleaning cloth.

Questions about this item

How loud or hot does the 12-core Core Ultra 7 255U get when the 17.3" laptop runs all day?

The 12-core Core Ultra 7 255U is built for steady all-day multitasking; the 17.3" chassis with 0.65 in thickness provides room for airflow, and integrated Intel Graphics keeps power draw moderate.

What cables or peripherals must I already own to use the 2 x USB-C 3.1 and 2 x USB-A 3.0 ports?

The box includes a 7-in-1 docking station with 1 TB storage, a Type-C data cable, a 3-in-1 charging cable and a 32 GB MicroSD card with adapter, so most connections work immediately.

Will my older USB 3.0 drives and HDMI 1.4 monitor work with the USB-A 3.0 and HDMI 2.1 ports?

Yes — the two USB-A 3.0 ports are backward compatible with earlier USB drives, and the HDMI 2.1 output drives legacy HDMI 1.4 displays at their native resolution.
