DELL Inspiron 3520 15 laptop i7-1255U 16GB 512GB 15.6 FHD touch

15.6" FHD touch laptop with Core i7-1255U

This 15.6-inch laptop pairs a 10-core Intel Core i7-1255U processor with 16GB of DDR4 memory and a 512GB PCIe solid-state drive. The touchscreen displays at 1920 x 1080 resolution and runs Windows 11 Home. It is suited to office work, study and everyday media consumption.

Setup and common issues

Windows 11 Home is pre-installed so the machine reaches the desktop after the standard out-of-box prompts. The chassis measures 14.11 x 9.27 x 0.83 inches and weighs 3.65 pounds. No optical drive is fitted and the keyboard lacks backlighting and a fingerprint reader.

Sustained-load behaviour

The 10-core processor has a base frequency of 1.2 GHz and can reach 4.7 GHz max turbo, while graphics are handled by the integrated Intel Iris Xe solution. Under continuous load the U-series chip will throttle to stay within its thermal envelope, so extended compile or render jobs run at lower clocks than short bursts. Buyers who need discrete graphics or a backlit keyboard should look elsewhere.
