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 EliteOne 840 G9 AIO is part of HP's EliteOne line — HP's business all-in-one desktop, bringing EliteDesk-level corporate security and manageability features into an all-in-one form factor for office use.
Tired of middlemen? Work with the actual repair team — Xigox. Desktop PC diagnostics in Masjid require different tools than laptop repair — desktop-specific diagnostic equipment. Xigox technicians use a step-by-step elimination process: PSU first, then RAM, GPU, then board. Accurate diagnosis first — saving you from replacing the wrong component.
We know you can't stay disconnected in Masjid. We plan this job for speed and efficiency. For most issues, our technicians finish the job within hours. We arrange secure collection from your Masjid home or office, perform the job using precision tools, and deliver it back to you.
One of the most common complaints about repair shops in Masjid is hidden charges after the job is done. Xigox operates differently. Before any work begins, our technician sends a WhatsApp quote covering parts and labour. There is zero ambiguity — the decision is entirely yours. The ₹350 diagnostic is credited 100% when you proceed with this repair.
Getting your HP fixed in Masjid is incredibly hassle-free. Step 1, call or WhatsApp us at +91 74997 61196 to describe your issue.

Once you agree, this job is executed with genuine parts — and your HP is returned to you. Most repairs done same day.
Swapping the whole board costs 3–5x more than fixing the fault on it. Xigox's on-site BGA rework station means engineers identify the specific chip and repair at the component level — saving customers thousands of rupees. Customers in Masjid seek us out for chip-level repair.
Don't just take our word for it. Xigox has earned a 4.9-star rating from 9,727+ customer reviews from customers across Mumbai MMR.
