HP OmniBook 3 Business Laptop

The HP OmniBook 3 is a 17.3 inch business laptop built around the Intel Core Ultra 7 255U processor with 12 cores and 14 threads. It ships with 16GB of DDR5 memory and a 512GB NVMe SSD. The 1920 x 1080 IPS display is non-touch. Windows 11 Pro is pre-installed.

Ready-to-use configuration

The unit arrives fully assembled with the operating system, drivers and Lifetime Office already activated. No hardware installation is required. The supplier notes the original box is opened by technicians for testing and upgrade installation. Buyers who want a sealed retail box should note this process.

Sustained workload behaviour

The 45W power supply and 3-cell battery support the Ultra 7 255U up to 5.2 GHz during extended sessions. Integrated Intel graphics handle typical business applications and 720p webcam video. Wi-Fi 7 and Bluetooth 5.0 maintain connectivity. Thermal throttling may occur under continuous maximum multi-core load.

Questions about this item

How can I confirm the 12-core Ultra 7 255U is reaching its 5.2 GHz boost on the 17.3" FHD IPS display after setup?

Open Task Manager's Performance tab and watch the CPU frequency graph while running a demanding workload; sustained speeds near 5.2 GHz show the processor is boosting correctly.

Which accessories are included with the 16 GB DDR5 / 512 GB NVMe configuration and what must I purchase separately?

The box contains the laptop, 45 W power adapter and documentation; a carrying case, external mouse or USB-C hub are not included and must be bought separately.

Should I choose the 16 GB DDR5 / 512 GB NVMe version or a higher-capacity model for business travel with the 4.43 lb chassis?

The 16 GB / 512 GB model balances weight and speed for typical office workloads; only step up if you regularly edit large video files or run multiple virtual machines.
