Questions about this item

How do I upgrade the 16GB DDR5 memory or the 1TB SSD later?

The seal is opened for upgrade only, and upgraded RAM or SSD carry a 1-year warranty from the upgrader while the remaining components keep the original 1-year manufacture warranty.

What thermal limit appears first when the 12-core Core Ultra 7 255U runs sustained workloads?

The integrated Intel Graphics share system memory and thermal budget with the CPU, so graphics-heavy tasks will hit the shared thermal ceiling before the processor alone would.

How loud and hot does the 17.3" chassis get during all-day use with Wi-Fi 7 active?

The 0.65-inch profile and 4.43 lb weight leave limited airflow space, so fans spin up noticeably under continuous load while the base and keyboard deck become warm to the touch.
