DELL Latitude 5520 laptop i7-1165G7 16GB 512GB 15.6" FHD Grade B

Product identity and target user

The Dell Latitude 5520 is a 15.6 inch business laptop equipped with an Intel i7 1165G7 processor, 16 GB of memory and a 512 GB solid-state drive. It runs Windows 11 Pro and includes a full HD display, webcam, backlit keyboard and a USB Type C port alongside HDMI and micro SD slots. The unit is sold as Grade B with visible key wear from heavy prior use. Buyers who need a pristine keyboard or a flawless chassis should look elsewhere.

Thermals, noise and power draw

Under typical office workloads the system runs quietly and the supplied Dell Type C AC adapter keeps the battery charged during normal use. The integrated Iris Xe graphics share system memory, so power draw stays modest when browsing, streaming video or working with documents. Fan activity remains low during light multitasking and the chassis stays comfortable to touch.

Sustained load behaviour

When the processor is pushed continuously the cooling system ramps up fan speed to manage heat, which increases audible noise. Performance may throttle slightly during extended heavy tasks such as large compiles or video exports because the thermal design prioritises quiet operation over peak speed. The good working battery supports mobile sessions but extended high-load periods will reduce run time noticeably.
