Hello Technicians, My laptop Acer Nitro 5, suddenly became dead. A few days before dying, the laptop screen just used to freeze. (Keyboard used to work though, having a backlit keyboard I could check that) But then the laptop went completely dead. I sent it to the service center, and they are telling me that the MOSFET keeps on blowing up. They said, whenever the put in a new one and turn on the laptop, it works. But when they shut it down and restart it, the MOSFET gets blown. They have no idea of the problem and are asking me to pay for display cable, keyboard, and battery so that they can figure out the problem. Please help me. I would be in your debt. Please save me, Jayesh Laptop specifications: Acer Nitro 5 AN515-52 RAM- 16GB Hard Disk: 1TB Processor: i5 8300H Graphics card: GTX 1050ti
