17.3" FHD IPS display

This Dell Inspiron 3781 laptop features a 17.3 inch Full HD screen with IPS technology for wide viewing angles. It runs on an Intel Core i3-7020U processor at 2.3GHz with 8GB DDR4 memory. A 256GB NVMe SSD provides fast storage and Windows 10 Pro is pre-installed.

Home office and student use

The large non-touch display and numeric keypad suit extended typing sessions, web browsing and video playback. Integrated Intel HD Graphics 620 handles everyday tasks but is not suited for modern gaming, video editing or 3D rendering workloads. Buyers needing dedicated graphics performance or a touchscreen should consider other options.

256GB NVMe SSD storage

The single 256GB NVMe drive determines how much applications and data can be stored locally before external drives or cloud services are required. No mechanical hard drive is present, so capacity cannot be expanded internally without replacing the boot drive. Verify that 256GB meets your offline storage needs before purchase.

Questions about this item

What are the dimensions of the 17.3 inch chassis for bag fit?

The laptop uses a 17.3 inch form factor with a full-size keyboard and numeric keypad; measure your bag against a standard 17 inch notebook footprint.

How do I access the 256GB NVMe drive for a clean Windows 10 Pro install?

Remove the bottom cover screws, lift the panel, locate the M.2 slot, insert the NVMe drive at an angle and secure it with the single retention screw.

When will the 8GB DDR4 memory need an upgrade for newer apps?

The system ships with 8GB DDR4 soldered or slotted; typical office workloads remain comfortable, but heavy multitasking may require a higher-capacity module later.
