Business laptop for everyday productivity

The Dell Latitude 3520 L3520-D7LWPL3 is a 15.6-inch laptop built around an Intel Core i5-1135G7 processor running at 2.40 GHz with 8 cores. It comes with 16 GB of DDR4 memory and a 512 GB drive. Windows 10 Professional is installed and a Windows 11 licence is included. Wi-Fi 6 provides wireless connectivity.

Steps up from 8 GB or smaller storage

Moving to 16 GB of DDR4 and a 512 GB drive removes the bottlenecks that appear when multitasking with many browser tabs, Office files or light creative apps on lesser configurations. The quad-core processor handles those workloads without the stutter common on dual-core machines. The jump is worth it when your current system feels sluggish during normal office multitasking.

Suits office workers and students needing reliable

This unit fits professionals who want a standard 15.6-inch form factor with a current Windows licence and modern Wi-Fi 6. Buyers who need discrete graphics for heavy 3D work, a higher-colour-gamut display for colour-critical design, or a lighter ultraportable chassis should look at other configurations.

商品問答

What screw pattern does the 15.6-inch chassis use for the bottom cover?

The service manual specifies nine captive screws around the perimeter and two under the rear rubber feet; remove all eleven before prying the cover.

Which cable must be disconnected first when replacing the 512 GB drive?

Disconnect the battery ribbon cable from the motherboard before lifting the M.2 retention screw, otherwise the drive slot remains powered.

How often should the fan assembly on this Latitude 3520 be cleaned?

Dell recommends blowing out the heatsink fins every six months in office use, or quarterly in dusty environments, to keep the Core i5-1135G7 within thermal limits.
