Everything you need to know before booking a diagnosis

10 questions answered

Xigox repairs HP EliteOne 840 G9 AIO All-in-One Touchscreen Not Working on Apple, HP, Dell, Lenovo, Asus, Acer, MSI, Microsoft and Samsung, and more.

It depends on the age and value of the all-in-one PC. 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. We also serve Kurla West, Kurla, Kurla East, so you can recommend us to neighbours too.
No. For any all-in-one PC that still powers on we take a full backup before touching the hardware, and for units that do not, we attempt recovery before repair. Your data is never accessed beyond what the repair requires, and nothing is copied off-site. Our service covers the full 400001 postal area in Mumbai.
For part replacements our technician works at your address in Mumbai. HP EliteOne 840 G9 AIO All-in-One Touchscreen Not Working 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 400001 postal area in Mumbai.
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 Mumbai (400001) 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 all-in-one PC repair lasts, so it is not somewhere we cut cost. Free pickup also available in Kurla West, Kurla, Kurla East and surrounding areas.
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. We also serve Kurla West, Kurla, Kurla East, so you can recommend us to neighbours too.
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. We've been serving Mumbai City district for over 15 years.
