17.3-inch AI laptop for business users
The HP OmniBook 3 ships with Windows 11 Home and a 17.3-inch FHD IPS panel at 1920 x 1080 resolution. An Intel Core Ultra 7 255U processor delivers 12 cores and 14 threads with a maximum turbo frequency of 5.2 GHz. Sixteen gigabytes of DDR5 memory and a 512 GB NVMe SSD handle everyday productivity workloads.
Fanless thermal profile and 45 W power supply
The system draws power from a 45 W adapter and a 3-cell battery. Integrated Intel graphics share system memory, keeping heat output low during typical office tasks. No discrete GPU means silent operation without active cooling noise. The chassis measures 15.65 x 10.09 x 0.65 inches and weighs 4.43 pounds.
Soldered 16 GB DDR5 cannot be upgraded
Memory is not user-replaceable, so buyers who need more than 16 GB must choose a different configuration. A single 512 GB NVMe drive provides the only internal storage slot. Connectivity includes Wi-Fi 7, Bluetooth 5.0, two USB-C 3.1 ports, two USB-A 3.0 ports and one HDMI 2.1 output.

Questions about this item
How do I install the 512GB NVMe SSD in the HP OmniBook 3, and which step do people get wrong?
The 512GB NVMe SSD is already installed. If adding a second drive, insert it into the M.2 slot at a shallow angle, press down, and secure the screw; the step most people miss is pressing the drive fully flat before tightening the screw.
What maintenance or replacement will the 16GB DDR5 memory need later?
The 16GB DDR5 memory is soldered to the board and cannot be upgraded or replaced separately. No user maintenance is required; if a fault occurs the mainboard must be serviced by a qualified technician.
What limit appears first on the Intel Core Ultra 7 255U during sustained workloads?
The 12-core, 14-thread processor reaches its 5.2 GHz turbo ceiling and then thermal throttling reduces clocks to stay within the 45 W power envelope, so sustained performance settles below the peak turbo frequency.
