Large-screen business laptop

The HP OmniBook 3 is a 17.3-inch business laptop built around an Intel Core Ultra 7 255U processor with 12 cores. It runs Windows 11 Pro and comes with 16GB of DDR5 5600 memory plus a combined 1.5TB of storage split between a 512GB internal SSD and a 1TB docking station. The Mica Silver chassis measures 15.65 by 10.09 by 0.65 inches and weighs 4.43 lbs.

Suited to desk-based professionals

This configuration suits office workers who value a spacious Full HD IPS panel for documents and video calls, and who benefit from the included docking station that adds ports and a terabyte of extra space. Buyers who need a touchscreen, a discrete GPU for heavy 3D work, or a lighter chassis for frequent travel should look at other models.

Steady output over long sessions

The integrated Intel Graphics and the Ultra 7 255U are designed for sustained multitasking rather than short burst speeds, so performance remains consistent during extended workdays. Wi-Fi 7 (802.11be) keeps network throughput stable when moving large files to the dock, and the backlit keyboard stays usable in low light without adding thermal load.

Questions about this item

Which ports on my existing monitor or dock will match the two USB-C 3.1 and two USB-A 3.0 sockets on this OmniBook 3?

The laptop provides two USB-C 3.1 ports and two USB-A 3.0 ports plus an HDMI 2.1 output, so any display or dock with USB-C 3.1, USB-A 3.0 or HDMI 2.1 will connect directly.

Will the 1 TB docking station that ships with this unit work with my older laptop that only has USB-A 3.0 ports?

The included 7-in-1 dock connects via USB-C, so an older laptop with only USB-A 3.0 would need a USB-A to USB-C adapter or cable to use the dock and its 1 TB storage.

How can I confirm the 16 GB DDR5 5600 memory and 1.5 TB combined storage are recognised after first boot?

Open Settings > System > About to see 16 GB DDR5 5600 listed under Device specifications, and check File Explorer for a 512 GB internal drive plus the 1 TB dock volume totalling 1.5 TB.
