Dell Precision 3561 — 15.6" Mobile Workstation, Intel i7-11850H, 32GB RAM, 256GB SSD, NVIDIA T600
A certified refurbished Dell Precision 3561 mobile workstation built for professional workloads — 8-core Intel Core i7-11850H, 32GB RAM, fast 256GB NVMe SSD and dedicated NVIDIA T600 graphics on a 15.6" Full HD anti-glare display, running Windows 11 Pro. Backed by a 12-month Reboot IT warranty. Please note: this unit's BIOS is password locked — it boots from the drive and runs completely normally, the only limitation is that BIOS/firmware settings cannot be changed.
⚠️ BIOS-locked unit: This workstation has a BIOS supervisor password set. It powers on, boots into Windows 11 Pro from the installed SSD, and operates normally for everyday use. You will not be able to enter the BIOS/UEFI setup menu to change firmware settings, alter boot order, or re-image from an external device. It is priced to reflect this. If you need full BIOS access (e.g. for enterprise re-imaging or custom firmware configuration), this unit is not suitable.
Why choose the Dell Precision 3561?
-
8-core Intel Core i7-11850H: A high-wattage H-series workstation CPU with Turbo up to 4.8GHz, built for sustained heavy workloads like CAD, rendering and data crunching — far beyond typical ultrabook performance.
-
Dedicated NVIDIA T600 graphics: Professional-grade GPU with 4GB GDDR6, certified for CAD/CAM and 3D applications such as SolidWorks, AutoCAD and Revit, and capable of driving multiple high-resolution displays.
-
32GB RAM for demanding projects: Generous memory handles large assemblies, multiple virtual machines and heavy multitasking without slowdown — and the DDR4 SODIMM slots remain user-upgradeable.
-
Fast 256GB NVMe SSD: Rapid boot, near-instant file access and snappy application launches for a responsive professional workflow.
-
15.6" Full HD anti-glare display: A sharp 1920×1080 matte panel that reduces reflections and eye strain during long working sessions.
-
Full-size professional connectivity: USB-C, USB 3.2 Type-A, HDMI, RJ-45 Gigabit Ethernet, SD card reader, Wi-Fi 6 and Bluetooth 5.1 — ready for any desk or docking setup.
Performance in professional use
The Precision 3561 is a genuine mobile workstation, and it shows under load. The 8-core i7-11850H paired with 32GB of RAM tears through engineering and design workloads — CAD models, BIM projects, photo and video editing, large datasets and multiple virtual machines all run smoothly. Where a standard business laptop would throttle, this Precision is engineered to sustain high performance.
The dedicated NVIDIA T600 GPU is the key differentiator. With ISV certifications for professional applications, it accelerates 3D viewport performance in SolidWorks, AutoCAD, Revit and Adobe Creative Cloud, and drives multiple external monitors with ease. Combined with the 256GB NVMe SSD for fast project loading, it makes a capable, portable platform for engineers, architects, designers and analysts.
For everyday office work the machine is equally at home — Microsoft Office, video conferencing and dozens of browser tabs barely register against its capacity. The full-size keyboard with number pad, RJ-45 Ethernet and generous port selection make it a true desktop-replacement that still travels. Because the BIOS is locked on this particular unit, it suits a buyer who wants a ready-to-use Windows 11 Pro workstation rather than one for custom firmware re-imaging.

Frequently asked questions
What does "BIOS locked" mean for this workstation?
The BIOS has a supervisor password set. The laptop powers on, boots into Windows 11 Pro from the installed SSD and runs normally for everyday use. The only limitation is that you cannot enter the BIOS/UEFI setup to change firmware settings, boot order, or re-image from external media. The price reflects this.
Is the NVIDIA T600 good for gaming?
The T600 is a professional workstation GPU optimised for CAD, 3D and creative applications rather than gaming. It will handle light and older games comfortably, but it is not designed as a high-end gaming card.
Can I upgrade the RAM or storage?
Yes — the 32GB DDR4 memory is in SODIMM slots and can be upgraded, and the M.2 NVMe SSD can be replaced or expanded. Note that BIOS-level changes (such as boot configuration) are not available on this locked unit.
Does it run Windows 11?
Yes — it ships with Windows 11 Pro pre-installed and meets all Windows 11 requirements (11th Gen CPU, TPM 2.0). It receives ongoing Microsoft security and feature updates.
