HP OmniBook 3 17.3 laptop
The HP OmniBook 3 is a 17.3 inch business laptop running Windows 11 Home. It uses an Intel Core Ultra 7 255U processor with 12 cores and 14 threads. The system includes 24GB of DDR5 memory and a 512GB NVMe SSD. A 1920 x 1080 IPS display provides a non-touch workspace.
Who this suits and who should look elsewhere
This laptop suits office workers who need a large screen for documents and video calls. The 720p webcam and Wi-Fi 7 support remote meetings. Buyers who want more storage or a dedicated graphics card for rendering should look at other configurations. The integrated Intel graphics limit 3D workloads.
Sustained load behaviour
Under continuous load the 45W power supply and 3-cell battery manage thermals for typical business tasks. The chassis measures 15.65 x 10.09 x 0.65 inches and weighs 4.43lb. Fan noise rises during long compile or export jobs but remains acceptable for open-plan offices.
