Everyday laptop for office and study

The Dell Inspiron 3480 is a 14-inch notebook built for daily productivity. It runs Windows 10 Pro on a dual-core Intel Core i3-8145U processor that reaches 3.9GHz. With 16GB of DDR4 memory and a 512GB solid-state drive, it handles web browsing, document work and video calls without delay.

Thermals and power in typical use

The integrated Intel UHD Graphics 620 shares system memory, keeping heat output modest during ordinary tasks. Fan noise stays low when editing documents or streaming video. The 14.0-inch HD panel at 1366 x 768 resolution draws little power, helping the compact chassis stay cool on a desk or lap.

Ports and bundled software for connectivity

An HDMI output lets you mirror or extend the screen to an external display. The built-in SD card reader transfers photos directly from cameras. Two USB 3.1 Gen 1 ports, LAN, Wi-Fi and Bluetooth cover wired and wireless peripherals. Windows 10 Pro adds BitLocker encryption and remote-desktop features for business environments.

Questions about this item

How do I install more memory in the Dell Inspiron 3480 and what step is often missed?

Remove the base cover, insert a DDR4 SO-DIMM into the free slot at 2400MHz, then reseat the battery connector before closing the case — skipping that reconnect stops the system from posting.

Which component in this 3480 will need replacement first after a few years of daily use?

The internal lithium-ion battery loses capacity after repeated charge cycles; the 512GB SSD and 16GB DDR4 memory have no moving parts and typically outlast the battery.

What limit appears first on the Core i3-8145U when the laptop runs a heavy workload for an extended period?

The processor drops from its 3.9GHz turbo to the 2.10GHz base frequency once the cooling solution saturates, reducing sustained performance.
