Doddathoguru is not a service point for this shop. The service point is Ganesh Complex, Electronic City, above the TVS showroom. You take the laptop to that room.
A key that types twice
Letters that repeat, keys that stick, or a row that stays dead after liquid are a keyboard. Missing keycaps are a keyboard too. Dust alone is not sold as a new mat. A setting in software cannot replace a key that snapped off. If the picture is cracked, the battery is weak, the disk is slow, the fan is loud, or pop-ups have taken over, those are named as their own lines.
The benefit is the right mat
You do not leave with a keyboard the machine did not need. Paid work starts when you accept the quote.
Dial 099724 47766 and say which letters misbehave. The services page, the Doddathoguru repair page, and the main service page are this bench.
