HP 255 G8 laptop Ryzen 5 5500U 16GB 256GB SSD 15.6" Dark Ash Silver

HP 255 G8 for everyday work

The HP 255 G8 laptop pairs a 6-core Ryzen 5 5500U processor with 16GB DDR4 memory and a 256GB NVMe SSD. Windows 11 Pro runs on a 15.6-inch IPS panel at 1920 x 1080 resolution. It suits students and office users who need a responsive machine for documents, web apps and video calls.

Sustained workload behaviour

The 5500U can lift its clock speed from 2.10 GHz toward 4 GHz when thermal headroom allows, keeping 6 cores and 12 threads fed by 12 MB L3 cache. Integrated Radeon graphics share system memory, so extended compiles or light render jobs stay smooth until the 45 W power limit or the 41 Whr battery capacity becomes the bottleneck.

Thermals noise and power draw

A 45 W adapter charges the 3-cell battery while the chassis measures 14.10 x 9.53 x 0.88 inches and weighs 3.8 lb. Under typical office loads the cooling fan stays quiet and surface temperatures remain comfortable. Heavy sustained tasks will spin the fan faster and warm the keyboard deck, but the 60 Hz display and efficient silicon keep overall power draw modest.
