Doddathoguru does not hold this bench. SAI Laptop Service holds it in Ganesh Complex, Electronic City, opposite Infosys. The laptop has to come to the bench.
A short battery life is a pack, not a mystery
If the charge falls off in an hour, or the pack has swollen, or it refuses current, they treat that as the battery. They do not call it a screen fault. A dark display is checked on its own, in case the panel, a cable, or the board is the cause. Dead keys, a slow disk that may need an SSD or a new hard disk, a loud fan, and malware are separate lines on the same quote.
You hear the line before you pay
The benefit is a named fault. Paid work starts after the quote, not before it.
Ring 099724 47766 and say how fast the charge drops. The services page, the Doddathoguru repair page, and the main tech page are the same walk-in.
