Yes — ₹350 for the inspection in Manickpur. Our technician diagnoses your computer and gives you a clear written estimate; if you go ahead with the repair, that ₹350 is adjusted against the total cost, so the inspection itself doesn't add to the bill.

Yes — out-of-warranty computers are most of what we handle in Manickpur. Once the manufacturer warranty lapses, authorised centres often quote near-replacement prices for a single component.

Dell Computer Repair in Manickpur — Xigox

If you are looking for Dell Computer repair in Manickpur that is not a brand service centre, this is it. Xigox has run an independent Dell bench since 2011, and our technicians work on Dell boards and firmware every day rather than treating them as an occasional job. More than 1,00,000 repairs and a 4.9-star average rating sit behind that.

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 401202 postal area within Palghar district, ensuring same-day response for every repair request. ₹350 inspection fee (refunded if you proceed with repair). Located near Ambadi Road, our service coverage extends across Manickpur and all surrounding localities. In addition to Manickpur, we also provide doorstep repairs and free pickup for lab work for customers in Navghar Vasai, Vasai Gaon, Vasai and other nearby areas.

How your Dell Computer gets serviced depends on the fault. Part swaps happen on-site anywhere in Manickpur; 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.

Your Dell Computer leaves with a written 90-day warranty covering both parts and labour. Same fault back inside that window and we redo it free — no argument, no diagnostic fee. WhatsApp support stays open afterwards for any question about the repair.

How it's done

How We Perform Computer No Power Issue

What our technicians do, what it requires, and how to tell you need it.

1 How It's Performed

For this specific fault, our technicians check for a battery that's fully dead versus a charging-circuit fault that just looks like a dead battery (the device may power on fine from the wall with the battery removed, which narrows the cause immediately).

Typical time: 30–60 minutes

2 What This Requires

  • Testing with a known-good, correctly-rated charger before concluding the fault is internal.
  • A multimeter check of the charging port's voltage output under load, not just a visual inspection.

3 When You Need This

  • The device won't turn on at all, with no lights, fans, or sounds of any kind.
  • It only charges or powers on at a specific cable angle, or not at all even with a known-good charger.
  • The charging light doesn't illuminate despite the charger being correctly plugged in.
