DELL Inspiron 3520 laptop i5-1135G7 16GB 256GB SSD + 1TB HDD 15.6" 120Hz Win 10 Pro

Inspiron 3520 dual-drive laptop

The Dell Inspiron 3520 combines an 11th Gen Intel Core i5-1135G7 processor with 16 GB of DDR4 memory. A 256 GB 2230 PCIe NVMe SSD handles the operating system and applications, while a 1 TB hard drive provides bulk storage. The 15.6-inch IPS panel runs at 120 Hz and 1920 x 1080 resolution. Windows 10 Pro 64-bit is pre-installed.

Home office and student workflows

This configuration suits everyday productivity, video calls and light content consumption. The dual-drive layout keeps the system responsive without sacrificing capacity for documents and media. Buyers who need discrete graphics for 3D rendering, gaming or GPU-accelerated workloads should look elsewhere. The single USB 2.0 port and HDMI output limit peripheral expansion for multi-monitor or high-speed accessory setups.

Thermal behaviour under load

The 65 W power adapter and 41 Whr three-cell battery support the 4.2 GHz turbo frequency for short bursts. Sustained multi-core workloads will trigger thermal throttling as the compact chassis manages heat from the four-core processor. Integrated Iris Xe graphics share system memory, so extended GPU tasks reduce bandwidth available to the CPU. Fan noise increases noticeably during prolonged heavy use.
