Scope of work — what the service covers
Supply and test an output-matched replacement adapter.
Repair internal adapter electronics — international safety standards require replacement, not field repair, for power supplies.
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
Adapters supply only what the device draws — a 90W adapter on a 65W laptop will not push excess power. Going lower is the risk: a 45W adapter on a 90W laptop will attempt to draw from the battery under load, causing warm connectors and premature battery wear.
Dell has used two barrel connector sizes across its Inspiron lineup — 4.5mm × 3.0mm (small pin) and 7.4mm × 5.0mm (big pin). The older 7.4mm connector is found on most pre-2015 Inspiron models; the newer 4.5mm on post-2015 models. The part page specifies which applies to this model.
Yes. If the replacement adapter fails to charge, the connection runs warm at the tip, or the charge indicator light does not activate within the warranty window, we replace it without additional charge.
The laptop draws from the battery exclusively. If the battery is depleted and the adapter is not charging, the machine will power off. Running on battery alone for extended periods accelerates cell wear. Replacing a faulty adapter promptly protects both the battery and the charging IC on the motherboard.
