Andapura is a place to start the trip. The trip ends at the walk-in in Ganesh Complex, Electronic City, above the TVS showroom and opposite Infosys. There is no Andapura counter.
A machine that will not start
If the laptop stays dark and silent, they check the board as well as the charger and the battery. This is a laptop board, not a desktop processor counter. When the machine does start but runs poorly, they still look at the screen, the keyboard, the disk, the heat, and malware, and they fit a part only when that part is the fault.
Why the first check is worth the walk
You find out whether it is the board, the power, or something simpler. The quote comes before any paid work.
Ring 099724 47766 and say the laptop does not power on. The services page, the Andapura repair page, and the main tech page describe the same bench.
