The Wipro Limited area is a campus people leave. SAI Laptop Service does not post anyone there. The bench they would be walking toward is Ganesh Complex, Electronic City, opposite Infosys and above the TVS showroom.
The laptop leaves the campus with you
At Ganesh Complex they can take a cracked screen, a fading battery, a dead keyboard, a crawling drive, hot wrists, or a virus. A crawling drive is answered with an SSD or a new hard disk. A clean is the malware job. They say which one your laptop needs.
You are not waiting on a campus bench
There is no SAI bench on that campus to wait for. Ganesh Complex is where the quote is spoken, and paid work stays waiting until then.
Contact 099724 47766 and describe the laptop before you exit the campus. The services page, the Wipro area repair page, and the main PC page are the bench off campus.
