Most Gamdevi repair shops handle HP the same way they handle every other make. We do not. Our HP technicians are trained specifically on HP ProDesk 400 G9 architecture — schematics, boardview files and firmware behaviour — which is why our first-time fix rate on HP work is so much higher than a general shop's.
Every HP component we fit is OEM-grade and batch-tested before it goes into your HP ProDesk 400 G9 — no aftermarket substitutes, no recycled pulls sold as new. You see the part cost and the labour cost separately on the estimate before we start, and the ₹350 inspection comes off the bill if you go ahead.
We actively serve the entire 400007 postal area within Mumbai Suburban district, ensuring same-day response for every repair request. ₹350 inspection fee (refunded if you proceed with repair).

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, we run a stress test alongside thermal imaging to confirm whether artifacts or crashes are a genuine GPU fault versus a cooling or driver issue, since those three causes look very similar on the surface but need completely different fixes.
Typical time: 1–4 hours
The model
The HP ProDesk 400 G9 is HP's mid-tier business desktop line — sitting below EliteDesk, offering business features at a more accessible price for small/medium businesses.
Tired of middlemen? Work with the actual repair team — Xigox. HP ProDesk 400 G9 Computer GPU Upgrade for desktops in Gamdevi need a different approach than laptop repair — a POST card, PSU tester, and RAM slot isolation. Xigox technicians use a methodical component-isolation sequence: starting from the most common fault point outward. This prevents unnecessary parts purchases — you don't replace a ₹8,000 GPU if the PSU is the real fault.
Quality matters for this issue. Because of this, our team strictly use genuine parts for your HP. Instead of unbranded components, we use trusted supply chains. This is how we help your issue stay durable, supported by our standard 90-day warranty.
Your HP model never limits what we can fix. Xigox engineers are trained across all major brands: HP, Dell, Lenovo, Asus, Acer, MSI, Toshiba, Samsung and Apple MacBook. Different manufacturers have unique design choices we account for in every repair. This depth of brand knowledge reduces repair time and lowers the chance of secondary damage.
Not sure what's wrong with your HP? Before you commit to any issue, Xigox conducts a comprehensive hardware inspection. While we charge a nominal ₹350, this amount is fully refunded when you approve the quote. Our local experts will explain the exact fault clearly so you can make an informed decision.
Replacing an entire board is often unnecessary than fixing the fault on it. Xigox's in-house BGA rework station means engineers diagnose the exact failing IC and replace only that component — a fraction of full board replacement. Gamdevi residents seek us out for chip-level repair.
Numbers speak louder. Xigox maintains a 4.9-star rating from 9,605+ customer reviews from customers across Mumbai MMR. Common praise includes: no surprise charges, fast turnaround, and genuine parts.
