17.3-inch FHD laptop for mobile professionals
The HP OmniBook 3 runs Windows 11 Pro on a 15th Gen Intel Core Ultra 7-255U processor with 12 cores and 14 threads, reaching 5.2 GHz turbo. Integrated Intel Graphics drive the 1920 x 1080 IPS panel at 60 Hz. The system includes 16 GB of DDR5 SO-DIMM memory and a 1 TB PCIe NVMe SSD.
Thermals and power in daily use
A 45 W USB-C power supply charges the 3-cell 41 Wh battery. The slim 1-inch profile houses the cooling solution for the 2.00 GHz base processor. No discrete GPU means lower sustained heat output during office workloads and video playback.
Build integration and expansion
Two USB 3.2 Type-C ports and HDMI handle external displays and peripherals. The 10.2 x 15.75 inch footprint weighs 4.4 lb. WiFi 7 and Bluetooth 5.4 provide modern wireless connectivity. Buyers needing discrete graphics or additional internal storage bays should look elsewhere.

Questions about this item
How do I install the 16GB DDR5 module and which slot mistake should I avoid?
The 16GB DDR5 SO-DIMM fits the single memory slot; do not force it into a non-existent second slot or an M.2 key.
What maintenance will the 3-Cell 41 WHr battery need later?
Expect gradual capacity loss after several hundred charge cycles; the battery is not user-replaceable without disassembly.
At what temperature limit does the 45W PSU throttle the Ultra 7-255U under sustained load?
The 45W Type-C adapter caps long-term power, so the processor reduces clocks once its thermal budget is reached.
