Everything you need to know before booking a diagnosis

10 questions answered

No. For any laptop that still powers on we take a full backup before touching the hardware, and for units that do not, we attempt recovery before repair.

For part replacements our technician works at your address in Sarni. Apple MacBook Pro Laptop Black Screen that traces back to the board needs microscope and hot-air rework, so that job comes to the lab — with free pickup and drop either way. We tell you which category yours is before you commit. Our service covers the full 401501 postal area in Sarni.
You bring it straight back. The same fault inside 90 days is covered under warranty — no second inspection fee, no diagnostic charge, no argument. The cover is there in writing so you do not have to just take our word for it. Customers across Sarni (401501) enjoy priority same-day scheduling.
We use OEM or OEM-grade components and tell you which one your quote covers before work starts. We do not fit unbranded aftermarket parts or recycled pulls sold as new — part quality is the single biggest factor in whether a laptop repair lasts, so it is not somewhere we cut cost. Trusted by customers throughout Palghar — rated 4.9★ across 9,727+ reviews.
That is what the ₹350 inspection is for. Symptoms overlap constantly — the same visible behaviour can come from three different components. We test rather than guess, then show you what we found before quoting. If the actual fault turns out to be something cheaper, the quote reflects that. Free pickup also available in Boisar, Pasthal, Navapur Boisar and surrounding areas.
Usually not for long. Left alone, most faults of this kind put stress on neighbouring components and turn a contained repair into a board-level one. If you cannot bring it in immediately, tell us the symptoms on WhatsApp and we will tell you honestly whether it can wait a few days or should be powered down now. Our service covers the full 401501 postal area in Sarni.

Apple MacBook Pro Repair in Sarni — Xigox

Most Sarni repair shops handle Apple the same way they handle every other make. We do not. Our Apple technicians are trained specifically on Apple MacBook Pro architecture — schematics, boardview files and firmware behaviour — which is why our first-time fix rate on Apple work is so much higher than a general shop's.

Every Apple component we fit is OEM-grade and batch-tested before it goes into your Apple MacBook Pro — 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 401501 postal area within Palghar district, ensuring same-day response for every repair request. ₹350 inspection fee (refunded if you proceed with repair). Located near Boisar East, our service coverage extends across Sarni and all surrounding localities. In addition to Sarni, we also provide doorstep repairs and free pickup for lab work for customers in Boisar, Pasthal, Navapur Boisar and other nearby areas.

How your Apple MacBook Pro gets serviced depends on the fault. Part swaps happen on-site anywhere in Sarni; 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.

Every Apple repair at Xigox is covered by a 90-day warranty on all parts and labour. If the same fault recurs within the warranty period, we fix it at no charge. Our after-repair WhatsApp support means we are always available to answer questions about your Apple MacBook Pro.

About the MacBook Pro

Best for: video/photo editing, software development, and sustained heavy workloads

The MacBook Pro is Apple's performance-oriented laptop, aimed at creative professionals, developers, and power users who need sustained CPU/GPU performance — active cooling, higher-refresh ProMotion displays on 14"/16" models, and more I/O than the Air.

Key features

  • Active fan cooling allows sustained high performance under video export, 3D rendering, and compilation workloads.
  • Soldered RAM/storage on Apple Silicon models — same upgrade limitation as the Air, more pronounced given the higher price point.
  • Liquid Retina XDR display on 14"/16" models — genuinely class-leading color accuracy and brightness for creative work.
  • Multiple Thunderbolt/USB-C ports plus, on larger models, HDMI and an SD card slot.
