How the service works
Consultation & triage
Contact us via the form, phone, or WhatsApp. Describe what the device is doing — or not doing. We ask three or four targeted questions to arrive before guessing begins.
Transparent quote
The engineer provides a written cost estimate before any work starts. No surprises. If the diagnostic reveals something beyond the original scope, you are informed and asked to approve before the engineer proceeds.
Engineer visit or workshop intake
For home or office visits, the engineer arrives within the agreed window with the correct component already in hand for common failures. Complex jobs — motherboard work, liquid damage — are handled at our Secunderabad workshop with documented check-in photos.
Installation, testing & sign-off
Every job ends with a functional test — not just a visual inspection. The engineer runs the device through its paces under load, confirms the repaired component is performing correctly, and hands back with a written 30-day workmanship warranty.

Frequently asked questions
The warranty covers the specific repair performed — if the same fault recurs within 30 days, we rectify it without additional charge. It does not cover new faults introduced after the device leaves the engineer, or physical damage.
An estimate is a range provided before diagnosis. A quote is a fixed price provided after the diagnostic identifies the specific fault and part required. We provide a quote — a number you can hold us to.
Both options are available. Common component replacements — keyboard, battery, screen, RAM — are handled on-site at your home or office. Motherboard repair, liquid damage, and chip-level work are workshop jobs.
We service Dell Inspiron, Latitude, XPS, Vostro, Precision, Alienware, and Studio lines. The engineer working on your device is familiar with the disassembly sequence and common failure modes for your specific model.
