Two Dell 15 DC15250 laptops can create very different experiences. TECHBUY lists 5315BLK with Core i5-1334U, 8GB RAM, Full HD touch and Windows 11 Home in S mode. The 71092479 uses the same processor line, 16GB RAM, a Full HD IPS 120Hz screen and Windows 11 Home with Office Home 2024. Before comparing prices, find out whether your essential apps work in S mode.
Will S mode block a school or company app?
Microsoft says Windows 11 in S mode installs apps exclusively from Microsoft Store. Check any exam software, input tool, device driver or internal company app that may come from elsewhere. Switching out is free through the Store, but it is one-way: the device cannot return to S mode.
Do not confuse leaving S mode with adding RAM or buying Office. The machine remains Windows 11 Home afterward, and separate apps still need valid licences. Ask school or company IT before setting up the laptop.
The operating system is not the only difference
TECHBUY lists 5315BLK with 8GB RAM, 512GB storage and a 15.6-inch Full HD touchscreen. The 71092479 has 16GB DDR5, 512GB storage and a 15.6-inch Full HD IPS 120Hz screen. Open your many-tab browser, meeting and spreadsheet on the 8GB model; touch cannot compensate if memory is the bottleneck.
If you mainly use mouse and keyboard, 120Hz may feel better while scrolling. If you point at the display in presentations, touch may help more. Run the same files on both, ask about memory expansion by SKU and do not assume all Dell 15 internals match.
Check the Office entitlement
TECHBUY describes 71092479 as including Office Home 2024. Confirm the entitlement for that exact code, activation method, account and invoice wording. Ask separately about Office for 5315BLK if you need it. Do not count an unconfirmed licence as a saving.
Compare current totals after any required RAM, software, setup and warranty. A suitable machine runs mandatory apps without a surprise on handover day.

Conclusion
The S-mode Dell 15 can fit when your apps are compatible and touch is useful, provided you understand that leaving S mode is irreversible. The Home-and-Office listing may fit a 16GB workload with the confirmed licence. Verify apps, licence and delivered configuration before paying.
