HP OmniBook 3 business laptop 17.3" Intel Ultra 7 255U 24GB 512GB Windows 11 Pro

17.3-inch business laptop for office work

The HP OmniBook 3 is a 17.3-inch business laptop built around an Intel Ultra 7 255U processor with 12 cores and 14 threads. It comes with 24GB of DDR5 memory and a 512GB NVMe SSD. The Full HD IPS display runs at 1920 x 1080 resolution without touch input. Windows 11 Pro is pre-installed.

Suited to desk-based professionals needing screen

This machine suits users who want a large display for spreadsheets, documents and video calls while staying on mains power most of the time. The 3-cell battery is rated for up to 10 hours, but real-world longevity will drop under continuous load. Buyers who need all-day untethered use or a lighter chassis for frequent travel should look elsewhere.

Sustained load behaviour with integrated graphics

Under prolonged workloads the Ultra 7 255U relies on its integrated Intel graphics and a 45W power supply. The cooling system must dissipate heat inside a 0.65-inch profile, so clock speeds will settle below the 5.2GHz maximum boost during extended compile, render or multi-tasking sessions. Surface temperatures near the hinge area rise noticeably after an hour of continuous CPU pressure.
