This is Acer s40-53-55ve model. Motherboard is dead according to the technicians I showed earlier. They sighted the bios chip is corrupt. But they couldn't find the appropriate parts for repair. But the laptop still powers on. It doesn't display anything. Once it powers on fan starts to run at full speed making loud noise. And laptop heats rapidly at near processor area. If anyone can repair and has appropriate parts or even a replacement motherboard at affordable price then message me
