Large-screen laptop for business users

The HP OmniBook 3 is a 17.3 inch FHD IPS laptop powered by an Intel Core Ultra 7 255U processor with 12 cores and 14 threads. It ships with 16GB DDR5 memory and a 512GB NVMe SSD. Windows 11 Home is pre-installed for immediate productivity.

Step up from smaller ultraportables

This model replaces compact 13 or 14 inch devices when extra display area and a full-size keyboard matter for spreadsheets and documents. The jump is worth it when workflows demand sustained screen real estate rather than maximum portability.

Consistent output during long sessions

The 45W power supply and 3-cell battery support steady performance for typical office workloads. Integrated Intel graphics handle everyday visual tasks without thermal spikes. Connectivity stays stable via Wi-Fi 7 and Bluetooth 5.0 throughout the day.

Questions about this item

What are the exact dimensions I need to clear for the 17.3-inch chassis?

Which screw or clip must be released first when swapping the 512 GB NVMe drive?

Remove the bottom cover screws, lift the panel, then unscrew the single M.2 retention screw before sliding the drive out at an angle.

When will the 45 W power supply or 3-cell battery typically need replacement?

Expect the 45 W adapter to last several years; the 3-cell battery usually holds useful capacity for 2–3 years of daily cycling.
