15.6" FHD Touch Laptop

The Dell Inspiron 3520 combines a 15.6 inch Full HD touchscreen with a 12th Generation Intel Core i7-1255U processor, 24GB DDR4 memory and a 256GB NVMe solid-state drive. It ships with Windows 11 Home and includes a 3-in-1 card reader, HDMI 1.4 output and two USB 3.2 ports for everyday productivity. The non-backlit keyboard and 720p webcam support standard office and video-call workflows.

41WHr Battery and 45W Adapter

A three-cell 41WHr battery pairs with a 45W power supply to handle typical workloads on the 10-core, 12-thread processor running up to 4.7 GHz. Integrated Intel UHD Graphics keep thermal output modest during document editing, web browsing and media playback. The compact chassis measures 14.15 by 9.25 by 0.90 inches and weighs 3.5lb, allowing passive airflow without loud fan activity under normal use.

XTREDURA Flash Drive Included

The bundle adds an XTREDURA flash drive for portable file transfers and backup alongside the internal 256GB NVMe SSD. Windows 11 Home activates immediately, while Bluetooth 5.0 and 802.11ac Wi-Fi connect peripherals and networks without extra dongles. Buyers who need larger local storage or discrete graphics for intensive creative work should consider other configurations.

Questions about this item

How do I install the 24GB DDR4 memory upgrade and what step is commonly missed?

The 24GB DDR4 2666MHz RAM is already installed by technicians before shipping; no user installation is required.

What maintenance will the 3-cell 41WHr battery need over time?

The 3-cell 41WHr battery is sealed inside the chassis; when runtime drops noticeably, a Dell-authorised service centre must replace the entire pack.

At what point does the 45W power supply limit sustained performance?

Under heavy load the 12th Gen Intel Core i7-1255U can draw more than the 45W adapter provides, so the system throttles clock speeds to stay within the power budget.
