Thermals noise and 45W power supply
A 45W power adapter charges the 3-cell lithium-ion battery. The system uses integrated Intel graphics rather than a discrete GPU. No fan specifications or acoustic measurements are provided in the source data. Power draw under load is not quantified beyond the supplied adapter rating.
LED mouse and port selection
An LED mouse is included in the box. Connectivity covers Wi-Fi 7 and Bluetooth 5.0. Physical ports comprise two USB-C 3.1, two USB-A 3.0, one HDMI 2.1 and a headphone/microphone combo jack. A 720p webcam sits above the display.

Questions about this item
How do I install the 32GB DDR5 memory and what step is often missed?
The 32GB DDR5 is factory-installed and not user-upgradable; the step often missed is verifying the installed capacity in Windows Task Manager before assuming an upgrade is possible.
What maintenance will the 45W power supply and 3-cell battery need later?
The 3-cell lithium-ion battery will gradually lose capacity and may need replacement after several hundred charge cycles; the 45W power supply requires no scheduled maintenance but should be replaced if the cable frays or the brick overheats.
What limit appears first during sustained heavy workloads on the Ultra 7 255U?
The 12-core Ultra 7 255U will hit its thermal ceiling first, causing clock speeds to drop from the 5.2GHz maximum to maintain safe temperatures within the 0.65in chassis.
