Dell Inspiron 3520 15 laptop
The Dell Inspiron 3520 15 laptop runs Windows 11 Home on a 12th Gen Intel Core i7-1255U processor with 10 cores and 12 threads. It ships with 16GB DDR4 memory and a 1TB SSD. The 15.6 inch FHD display delivers a 1920 x 1080 resolution at 120Hz. Integrated Intel Iris Xe graphics handle visual output.
Thermals noise and power
The slim chassis measures 14.11 x 9.27 x 0.82 inches and weighs 3.65 lbs, limiting thermal headroom under sustained loads. Fan noise will rise during heavy multitasking or extended video playback. The efficient 10-core architecture helps moderate power draw during typical office and web workloads.
Display specification
The 15.6 inch panel uses a WVA anti-glare coating with 250 nit brightness and a narrow border design. A 120Hz refresh rate smooths motion for video and casual use. Buyers who need higher colour accuracy or brighter output for outdoor work should note the 250 nit ceiling.

Questions about this item
How do I add more storage to the 1 TB PCIe SSD, and which screw do people forget?
Remove the base cover, insert an M.2 2280 drive into the open slot, and secure it with the single silver screw — that tiny screw is the one most often dropped.
When will the 16 GB DDR4 memory need to be replaced or upgraded?
The memory is soldered to the board, so it cannot be upgraded; plan on keeping the 16 GB for the life of the laptop.
At what point does the Intel Core i7-1255U hit its thermal limit during a long render?
Sustained loads push the 10-core CPU to its 4.7 GHz boost ceiling, then the cooling system throttles clocks to stay within the 250-nit display's thermal envelope.
