Claim - World’s Most Durably Slim 14-inch Consumer Notebook* 

*Based on publicly available information and HP’s internal analysis of 14-inch display consumer notebooks from major manufacturers with Windows Home or MacOS as of December 2025. Slimness is determined by the notebook’s rear height of 10.7 millimeters. Rear height measurement is near the back edge where the chassis bottom cover taper ends, excluding transition area to rubber feet and hinge cap. Durability is measured by the notebook’s passing of 20 MIL-STD-810H test items performed by HP, including drop, vibration, handling, shock, dust, humidity, altitude, radiation, and extreme temperature tests. Testing is not intended to demonstrate fitness of U.S. Department of Defense (DoD) contract requirements or for military use. Test results are not a guarantee of future performance under these test conditions. Accidental damage requires an optional HP Accidental Damage Protection Care Pack.
