Ready for work and study

The Dell Inspiron 3520 pairs an 11th Gen Intel Core i5-1135G7 processor with 8GB DDR4 memory and a dual-drive layout of 512GB NVMe SSD plus 1TB HDD. Windows 10 Pro 64-bit is pre-installed. The 15.6 inch IPS panel runs at 1920 x 1080 resolution and a 120 Hz refresh rate. Integrated Intel Iris Xe graphics handle everyday visual tasks without a discrete card.

Fits a mobile desk

A 65 W power supply and a 3-cell 41 WHr battery keep the system running away from a socket. Connectivity covers 802.11ac Wi-Fi and Bluetooth 5.0 for peripherals. Physical ports include one USB 2.0, HDMI, an SD card reader and a headset jack. The chassis measures 14.11 x 9.27 x 0.74 inches and weighs 3.6 lb, so it slides into a standard backpack.

Steady under load

The four-core, eight-thread CPU reaches 4.2 GHz turbo when thermal headroom allows, while the 8 MB L3 cache keeps frequent data close. Shared system memory feeds the integrated GPU, so sustained graphics work draws from the same 8 GB pool. The SSD accelerates boot and application launches, while the HDD provides bulk capacity for archives and media libraries.

Questions about this item

Does the 4.2 GHz turbo boost hold during long workloads?

The i5-1135G7 reaches 4.2 GHz turbo but sustained clocks depend on the 65 W adapter and 41 Whr battery thermal limits.

How loud and hot does the chassis get under all-day load?

Integrated Iris Xe graphics and a 15.6" 120 Hz panel share the 65 W power budget; fan noise and surface temperature rise with continuous CPU/GPU demand.

What RAM type must already be installed for the 8 GB to work?

The system uses DDR4 SO-DIMM modules; the 8 GB fitted is DDR4 and any upgrade must match that generation.
