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.

Questions about this item

Will the 24 GB DDR5 memory and 512 GB NVMe SSD work with my existing USB-C 3.1 dock?

The laptop provides two USB-C 3.1 ports that carry data and display signals, so a dock using that standard will connect without extra adapters.

Can I keep using my older USB-A 3.0 mouse and keyboard with the 2 x USB-A 3.0 ports?

Yes, the two USB-A 3.0 ports are backward compatible with USB 2.0 and 1.1 peripherals, so existing mice and keyboards will function normally.

How do I verify the Intel Ultra 7 255U is reaching its 5.2 GHz boost after setup?

Open Task Manager, select the Performance tab, choose CPU and watch the live clock speed while running a demanding task; it should show frequencies up to 5.2 GHz.
