Home & Business Laptop

The Dell Inspiron 3520 is a 15.6 inch laptop built for home and business users who need a 120 Hz Full HD IPS display, 16 GB DDR4 memory and a 256 GB 2230 PCIe NVMe SSD. It runs Windows 11 Pro on an 11th Gen Intel Core i5-1135G7 processor with Intel Iris Xe integrated graphics. Buyers who need a dedicated GPU or more internal storage should look elsewhere.

Thermals & Power

A 65 W power supply charges the 3 cell 41 WHr battery while the system handles everyday workloads. The Carbon Black chassis uses integrated graphics, which keeps typical power draw and fan noise lower than discrete GPU designs. Wireless connectivity relies on 802.11ac Wi-Fi and Bluetooth 5.0.

Sustained Load Behaviour

Under prolonged multi-core tasks the 4 core 8 thread CPU can reach 4.2 GHz turbo before thermal limits throttle clocks. The 120 Hz panel remains responsive, but integrated graphics performance caps frame rates in heavy 3D work. The 256 GB NVMe SSD delivers consistent read and write speeds without thermal throttling.

Questions about this item

How do I add a second 2230 PCIe NVMe SSD to the Inspiron 3520, and what step is often missed?

Remove the base cover, insert the 2230 drive into the open M.2 slot at a 30-degree angle, then secure it with the single screw; the step often missed is re-enabling the second drive in the BIOS before Windows sees it.

Which component will need replacement first during the laptop's life?

The 3-cell 41 WHr battery will degrade before the soldered 16GB DDR4 memory or the 256GB NVMe SSD, so plan a battery swap once runtime drops below your needs.

What thermal limit appears first when the i5-1135G7 runs at 4.2 GHz for extended periods?

The 65W power adapter and shared heat pipe cannot dissipate sustained turbo loads, so the CPU throttles to its base 2.40 GHz once the chassis hits its thermal ceiling.
