Business-ready 15.6" laptop

The Dell 15.6" business laptop ships with Windows 11 Home and an Intel Core i7-1355U processor featuring 10 cores and 12 threads. It includes 16GB of DDR4 3200 memory and a 1TB PCIe Gen 4x4 NVMe M.2 solid state drive. The 1920 x 1080 FHD IPS panel is non-touch and the chassis is finished in black.

Suits office workers and mobile professionals

This configuration suits office workers and mobile professionals who need a responsive system for productivity applications, video calls and multitasking. Buyers who need discrete graphics performance for 3D rendering, heavy video editing or modern gaming should look at a different class of machine. Users requiring a touchscreen or a higher-resolution display will also need an alternative model.

Sustained workloads on integrated graphics

Under sustained load the Intel UHD Graphics share system memory and thermal headroom with the CPU, so extended 3D or compute tasks will throttle clock speeds to stay within the 65W adapter and 41Wh battery limits. The 10-core processor maintains solid throughput for long document, spreadsheet and browser sessions, while the NVMe drive keeps file access consistent during prolonged use. Fan noise increases noticeably during continuous heavy work.

Questions about this item

What RAM type and speed must I already have if I want to add more memory to the 16GB DDR4 3200 configuration?

The laptop uses DDR4 3200 modules, so any additional memory must match that generation and speed.

Will my older USB 2.0 peripherals work with the USB 2.0 port and the USB 3.2 Gen 1 ports on this laptop?

Yes, the USB 2.0 port runs at 480 Mbps and the USB 3.2 Gen 1 ports are backward compatible with USB 2.0 devices.

How can I confirm the 1TB PCIe Gen 4x4 NVMe SSD is recognised at full speed after setup?

Open Task Manager, select the Performance tab, choose the drive and verify the interface shows NVMe with a link speed indicating PCIe Gen 4 operation.
