HP OmniBook 3 17.3-inch business laptop

The HP OmniBook 3 is a 17.3-inch laptop built for business users who want a large workspace in a standard chassis. It runs Windows 11 Pro and ships with a lifetime Office licence. The Intel Core Ultra 7 255U processor delivers 12 cores and 14 threads with a maximum turbo frequency of 5.2 GHz. Integrated Intel graphics handle everyday visual tasks without a discrete GPU.

Sustained workload behaviour with 24GB DDR5

The 24GB DDR5 memory configuration supports heavy multitasking across many browser tabs, documents and video calls. Because the Ultra 7 255U is a 15 W-class chip, clock speeds will settle below the 5.2 GHz peak during long renders or compiles. Thermal management relies on the slim 0.65-inch profile, so extended all-core loads will run warmer and quieter than thicker workstations. The 512GB NVMe SSD keeps boot and application launches consistent over time.

Build practicality and daily connectivity

The chassis weighs 4.43 lb and measures 15.65 by 10.09 inches, making it portable enough for daily carry yet stable on a desk. A 720p webcam and stereo speakers cover conference calls without peripherals. Ports include two USB-C 3.1, two USB-A 3.0, one HDMI 2.1 and a combo audio jack for monitors, docks and headsets. Wi-Fi 7 and Bluetooth 5.0 provide modern wireless links, while the 45 W power supply keeps the 3-cell battery topped up.
