Built for business workflows

The HP OmniBook 3 is a 17.3 inch laptop aimed at professionals who need a large workspace and responsive multitasking. An Intel Core Ultra 7 255U processor with 12 cores and 14 threads reaches 5.2 GHz, while 24GB of DDR5 memory and a 1TB NVMe SSD keep data moving quickly.

Thermals and power in daily use

A 45W power supply feeds the system during typical office tasks, web browsing and video calls. Integrated Intel graphics handle the 1920 x 1080 IPS panel without a discrete GPU, helping keep heat and fan noise low for a 4.43lb chassis measuring .65 inches thin.

Ports and expandability for the desk

Two USB-C 3.1 ports and two USB-A 3.0 ports connect peripherals and external drives, while HDMI 2.1 drives an additional monitor. Wi-Fi 7 and Bluetooth 5.0 handle wireless links, and the 720p webcam supports conferencing. Buyers who want more storage or a second graphics card will need a different form factor.

Questions about this item

How do I add more memory to the HP OmniBook 3 and what step should I avoid?

The 24GB DDR5 is soldered to the board; there is no user-accessible slot, so do not open the chassis expecting to insert a module.

Which component will likely need replacement first during the laptop's life?

The 3-cell battery paired with the 45W power supply will degrade before the 1TB NVMe SSD or the soldered 24GB DDR5.

What thermal limit appears first when the Intel Core Ultra 7 255U runs sustained workloads?

The 15.65 x 10.09 x 0.65 in chassis and 45W adapter constrain the 12-core processor, so skin-temperature limits throttle clocks before the 5.2GHz boost can hold.
