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

Purpose-built business laptop

The HP OmniBook 3 delivers a 17.3 inch Full HD IPS display driven by an Intel Ultra 7 255U processor with 12 cores and 14 threads. 32GB of DDR5 memory and a 512GB NVMe SSD provide responsive multitasking and fast storage for office workloads. Windows 11 Home, Wi-Fi 7 and Bluetooth 7 handle modern connectivity demands. It suits professionals who need a large screen and strong integrated graphics in a standard chassis.

Thermals and power in daily use

A 45W power supply feeds the system during typical productivity tasks such as document editing, video calls and web browsing. The 3-cell lithium-ion battery supports up to 10 hours of mixed use on a single charge. Fan noise remains low during light loads while the aluminium frame helps spread heat across the palm rest. Surface temperatures stay comfortable for extended desk sessions.

Behaviour under sustained load

During prolonged compile jobs or large spreadsheet calculations the 12-core processor maintains high frequencies up to 5.2 GHz within its thermal envelope. Integrated graphics share system memory, so extended 3D or video render tasks will draw more heavily on the 32GB DDR5 pool. The single HDMI 2.1 port supports one external 4K display for additional workspace. Buyers who need discrete GPU acceleration or a second high-speed video output should consider other form factors.
