Anyone found it?? I have a problem with this model, 3v line shorted, chip was damaged, I replaced sy8371b and kb9542q, flashed KBC and laptop works but it turns off backlight randomly and enters suspension, I have keyboard unplugged. I cannot locate lid switch circuit or any circuit without schematics or KBC pinout, I suspect maybe this controller I ordered in AliExpress is faulty but it costed around 20 USD 😔. I need to be sure
