It depends on the age and value of the laptop. As a rule, if the repair costs less than a third of a comparable replacement and the rest of the hardware is healthy, repairing is worth it. After the inspection we tell you the honest repair cost and what a replacement would run, so the comparison is yours to make — we do not push a repair that is not worth doing. Trusted by customers throughout Thane — rated 4.9★ across 9,727+ reviews.
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.

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. Our service covers the full 401105 postal area in Indralok.
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. Our service covers the full 401105 postal area in Indralok.
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 Golden Nest, Maxus Mall, Navghar Bhayandar and surrounding areas.
