Need a Chip-Level Laptop Repair Expert in Thane or Nearby

Hey everyone, I’m facing a major issue with my laptop. It suddenly stopped turning on after I restarted it. I took it to a local repair shop, and they told me the motherboard is faulty. However, I’m not entirely convinced by their diagnosis and want to get a second opinion. Can anyone recommend a reliable chip-level laptop repair expert in Thane or nearby areas? Someone experienced who can give an honest and accurate diagnosis would be ideal. Any leads would be greatly appreciated! It's a gaming laptop Thanks in advance!
