HP OmniBook 3 business laptop 17.3" FHD Intel Ultra 7 255U 32GB DDR5 512GB NVMe Windows 11 Pro

17.3-inch business laptop with Intel Ultra 7 255U

This 17.3-inch business laptop ships with Windows 11 Pro and a Full HD IPS display. It is built for professionals who need a large screen, 32GB of DDR5 memory and a 512GB NVMe drive in a standard black chassis. The Intel Ultra 7 255U processor provides 12 cores and 14 threads with a maximum turbo frequency of 5.2 GHz.

Thermals and power with a 45 W supply

The system draws power from a 45 W adapter and uses a three-cell lithium-ion battery rated for up to 10 hours of mixed use. Integrated Intel graphics keep heat output modest during typical office workloads such as document editing, video calls and web browsing. Fan noise remains low in these scenarios.

Behaviour during sustained workloads

Under continuous multi-threaded load the 12-core processor can maintain higher frequencies within its thermal envelope, though sustained performance will be limited by the compact 0.65-inch chassis and the 45 W power budget. Surface temperatures may rise noticeably during long rendering or compilation sessions. The single HDMI 2.1 port supports external displays for extended workflows.
