The Wipro Limited area is a workplace people leave at the end of a shift. It is not a SAI counter, and SAI does not keep a desk inside that campus. The counter is Ganesh Complex, Electronic City, opposite Infosys and above the TVS showroom.
The laptop still has to be carried in
A cracked screen, a battery that quits, a dead keyboard, a slow drive, a hot palm rest, or a virus are handled at that counter. An SSD or a new hard disk is for a drive that is slow or failing. A clean is for malware. They tell you which of those they found.
The benefit is a counter you can walk into
You are not depending on a campus desk that is not there. You hear the quote at Ganesh Complex before any paid work.
Use 099724 47766 and describe the laptop before you leave the area. The services page, the Wipro area repair page, and the main tech page are this shop.
