The useful part of a visit to SAI Laptop Service in Electronic City is the sentence that names the fault before any money changes hands. This site does not publish a price list. You describe what you see: a cracked or black screen, a battery that dies early or swells, keys that stick or a spill, a slow or failing drive, a hot palm rest, or pop-ups and locked files. The counter says which of those it is, and which part will be fitted. You decide before paid work starts.
How the jobs stay separate
A screen is replaced when the panel is the fault. A battery is replaced when the pack is swollen, dies early, or will not charge. A keyboard is fitted when the keys are the fault, not when crumbs are the whole story. An SSD or a new drive replaces a slow or failing hard disk. The fan and heat sink are the heat job. Malware removal and a system clean are the pop-up job. A fresh Windows install is another job again, for a machine that will not boot or for a fresh start.
