Product identity

The HP 17.3-inch HD+ touchscreen laptop ships with an Intel Core Ultra 7 255U processor, 64GB of DDR5 5600 memory and a 2TB PCIe Gen 4x4 NVMe SSD. It targets business users who need a large anti-glare display, Windows 11 Pro and AI-ready silicon in a single chassis.

Thermals and power

A 41 Wh battery pairs with a 45 W adapter, while the 12-core 14-thread CPU runs at a 2.4 GHz base and can reach 5.2 GHz. Integrated Intel Graphics keep the thermal load modest during typical office workloads, so fan noise stays low in normal use.

Sustained load behaviour

Under prolonged multi-threaded work the 12 MB cache and DDR5 bandwidth help maintain throughput, yet the U-series power envelope and shared graphics memory limit peak compute duration. Buyers who need discrete GPU acceleration or longer unplugged runtime should look elsewhere.

Questions about this item

How is the 2 TB PCIe Gen 4x4 NVMe M.2 SSD installed, and which step do people often miss?

The drive slots into the M.2 connector at a shallow angle, then is secured with the single retaining screw; the step most often missed is fastening that screw before reassembling the chassis.

What maintenance or replacement will the 41 Wh 3-cell Li-ion battery need later?

The sealed 41 Wh battery is not user-replaceable; when runtime degrades, a qualified technician must swap the entire pack.

What limit appears first during sustained heavy workloads on the Core Ultra 7 255U?

The 45 W power adapter and 41 Wh battery cap sustained performance, so thermal throttling or reduced clock speeds occur before the 5.2 GHz boost can be maintained.
