15.6" FHD Business Laptop with i7-1355U

The Dell 15 pairs a 10-core Intel Core i7-1355U processor with 64GB of memory to handle demanding office workloads. Integrated Intel UHD Graphics drive the 15.6-inch 1920 x 1080 non-touch display. Windows 11 Pro comes pre-installed for professional environments. The silver chassis weighs 4.28 lbs and measures 14.11x9.25x0.69 inches.

1TB Docking Station and Accessory Bundle

A 7-in-1 docking station adds 1TB of external storage and expands connectivity beyond the laptop's three USB ports and HDMI 1.4 output. The set also includes a 32GB microSD card with adapter, a Type-C data cable, a 3-in-1 charging cable and a suede cleaning cloth. These extras turn the notebook into a complete desk-ready workstation.

3TB Combined Storage for Large Projects

The internal 2TB drive and bundled 1TB dock provide 3TB total capacity for extensive document libraries, media archives and local backups. Wi-Fi 6 and Bluetooth support wireless peripherals and cloud sync. Buyers who need discrete graphics for rendering or multiple external 4K displays will find the integrated GPU and single HDMI 1.4 port limiting.

Questions about this item

Can the 64GB memory be expanded later or will it need replacement?

The 64GB memory is already at a high capacity for this platform; no larger SODIMM modules are confirmed compatible, so plan to keep the factory configuration.

What thermal limit appears first during continuous heavy workloads on the i7-1355U?

The 10-core i7-1355U with integrated UHD graphics will hit its power and temperature ceiling before the cooling system can dissipate heat, causing clock-speed throttling under sustained load.

How loud and hot does the chassis get when the laptop runs all day with the dock attached?

With the 15.6-inch chassis and integrated graphics, fan noise becomes noticeable and the bottom surface warms up during all-day use, especially while the dock charges the system.
