10 questions answered
Send us your question on WhatsApp or call — a technician will answer.
Most Sion repair shops handle Dell the same way they handle every other make. We do not. Our Dell technicians are trained specifically on Dell Computer architecture — schematics, boardview files and firmware behaviour — which is why our first-time fix rate on Dell work is so much higher than a general shop's.
Parts for Dell Computer models are held in stock rather than ordered after you book, so most repairs are not waiting on a supplier. Screens, batteries, keyboards, charging boards and flex cables are all OEM-grade. You approve a written estimate first, and the ₹350 inspection is credited back against the repair.
We actively serve the entire 400022 postal area within Mumbai City district, ensuring same-day response for every repair request. ₹350 inspection fee (refunded if you proceed with repair). Located near Pratiksha Nagar, our service coverage extends across Sion and all surrounding localities. In addition to Sion, we also provide doorstep repairs and free pickup for lab work for customers in Dharavi, Sion East, Sion West and other nearby areas.
How your Dell Computer gets serviced depends on the fault. Part swaps happen on-site anywhere in Sion; board-level work goes to the bench because it needs proper rework equipment. Either way collection and return are free, and you get progress updates rather than having to chase us.
We back Dell work with a 90-day parts-and-labour warranty in writing, not just a verbal promise. If your Computer does come back with the same fault, we cover it. You keep a direct WhatsApp line to the team that did the work.

Product lines
Xigox keeps Dell parts and service documentation for 7 Dell series, so Computer OS Upgrade on a Alienware, Inspiron, Latitude and OptiPlex machine is handled by someone who has seen that chassis before. We regularly take in Alienware, Inspiron, Latitude and OptiPlex, along with Precision, Vostro and XPS units for Computer OS Upgrade in Sion. Specific Dell models on our current service list include Dell Inspiron Desktop, Dell OptiPlex 7010, Dell Precision 3660 and Dell Vostro 3910. If your Dell model is not listed, it is almost certainly still covered — send us the model number on the base sticker and we will confirm parts availability before you book.
The Dell Precision 3660 is Dell's workstation line — ISV-certified (for software like AutoCAD, SolidWorks) with ECC memory options and professional-grade GPUs, built for engineering, architecture, and data-science workloads.
Worth knowing for this repair: ECC memory support on many configurations, reducing the risk of data corruption under sustained heavy computation.
The Dell Vostro 3910 is Dell's small-business laptop/desktop line — positioned between the consumer Inspiron and the enterprise Latitude/OptiPlex lines, aimed at small businesses that want manageability without full enterprise IT overhead.
The Dell XPS 8960 is Dell's premium consumer desktop tower, offering stronger components and build quality than Inspiron desktops while remaining more accessible than the Precision workstation line.

How it's done
What our technicians do, what it requires, and how to tell you need it.
When you want more capacity or speed rather than just a fix, for an installation or reinstall, we back up your existing files first, install a genuine, correctly licensed copy of the operating system, and install the specific driver set your exact hardware model needs — not a generic driver pack that happens to install without errors.
Typical time: 30–90 minutes
