Hello,i new here. i currently repairing this laptop, it was missing gate voltage at mosfet u30, the track between d16 and mosfet was damage, i've added a jumper and a 10k resistor but didn't add the filter capacitor c314, the laptop was powering on ok. But when i connect the hard drive or dvd drive, the laptop doesn't power on and the resistor r213 heats up, can anyone please help
