HP OmniBook 3 business laptop

The HP OmniBook 3 is a 17.3-inch business laptop running Windows 11 Home. It uses an Intel Ultra 7 255U processor with 12 cores and 14 threads reaching up to 5.2 GHz. Integrated Intel graphics drive the FHD IPS display. The system includes 24GB DDR5 memory and a 1TB NVMe SSD. It suits professionals needing a large screen for office applications and video calls.

Check ports and wireless before ordering

The laptop provides two USB-C 3.1 ports, two USB-A 3.0 ports and one HDMI 2.1 output. Wireless connectivity uses Wifi7 and Bluetooth 5.0. Verify that your existing monitors, docks and peripherals match these interfaces. The 720p webcam and combo audio jack handle standard conferencing. No optical drive is fitted.

Sustained load behaviour

The 45W power supply feeds a 3-cell battery rated for up to 10 hours of mixed use. Under continuous multi-core workloads the Ultra 7 255U will throttle to stay within its thermal envelope. Integrated graphics share system memory, so extended rendering or heavy multitasking reduces available RAM bandwidth. The chassis measures 15.65 by 10.09 by 0.65 inches and weighs 4.43lb.

Questions about this item

Does the box include the 45 W power supply and the LED mouse, or must I buy them separately?

The 45 W power supply is included; the LED mouse is listed in the supplier title, so it ships in the same package.

Should I choose the 24 GB DDR5 model or is a smaller memory option available?

Only the 24 GB DDR5 configuration is offered; there is no lower-capacity version to select.

What does the 5.2 GHz boost clock mean for everyday workloads on the Ultra 7 255U?

The 12-core, 14-thread processor can reach 5.2 GHz for short bursts, speeding up office apps and light multitasking before returning to lower sustained speeds.
