Dell Inspiron 15 3511 — 15.6" Full HD Laptop
A 15.6-inch laptop with a quad-core Intel Core i5-1135G7, 8GB of memory and a 512GB NVMe SSD, running Windows 11 Home. Supplied with a 12-month Reboot IT warranty and free Australian shipping.
Key Benefits
-
512GB of fast storage — a generous NVMe SSD — twice the capacity of most machines at this level, with room for years of documents, photos and an offline cloud copy.
-
Quad-core 11th Gen processor — the i5-1135G7 runs four cores and eight threads to 4.2GHz — comfortable for study, home office and everyday work.
-
15.6" Full HD display — 1920 x 1080 with an anti-glare finish, so documents and spreadsheets show far more than the HD panels common at this level.
-
Full-size keyboard with numeric keypad — the 15.6-inch chassis makes room for a number pad, useful for study, budgeting and data entry.
-
Windows 11 Home included — genuine and activated, ready to sign in and use.
-
Free Australian shipping — tracked delivery anywhere in Australia at no extra cost, backed by a 12-month warranty.
Performance in Use
The Core i5-1135G7 is a four-core, eight-thread processor at up to 4.2GHz. For study, home office and general use it is comfortably quick — a browser session, Microsoft 365, a video call and streaming all run together without difficulty.
The 512GB NVMe SSD is the standout specification. Most machines at this level ship 256GB, and doubling that removes the need to manage space or offload files. Combined with fast NVMe transfer speeds, boot and application launch are immediate.
One detail worth knowing: this configuration ships with a single 8GB memory module. Intel only permits the Iris Xe graphics designation when a system runs dual-channel memory, so with one module fitted the same silicon reports as UHD Graphics. Adding a second 8GB module is inexpensive, doubles the memory to 16GB, and unlocks Iris Xe — the single best upgrade available for this machine.

Frequently Asked Questions
Is the battery replaced?
Batteries are tested, not automatically replaced. Grade A units hold 70% or more of original design capacity and Grade B units 50–70%. Every battery carries a 30-day warranty.
Can I upgrade the memory?
Yes, and it is the upgrade worth making. The machine ships with a single 8GB module, so adding a second both doubles memory to 16GB and enables dual-channel mode, which activates Intel Iris Xe graphics.
Why does it show UHD Graphics rather than Iris Xe?
Intel only permits the Iris Xe designation when the system runs dual-channel memory. With one module fitted the same silicon reports as UHD Graphics — adding a second module changes it.
Is this Windows 11 Home or Pro?
Home. It suits personal, study and small business use. If you need domain join, Group Policy or BitLocker, choose a machine with Windows 11 Pro.
Can I upgrade the SSD?
Yes. The 512GB M.2 NVMe drive is accessible under the base panel, though at 512GB most users will not need to.
Is the operating system genuine?
Yes. Windows 11 Home is installed and activated against the licence embedded in the unit.
What are the delivery options?
Free standard AU shipping with tracking is included.
