Re: ASUS Tuf Fx505dd rev2. Does not start up, does not charge the battery.
Unfortunately it was not possible to fix it. I replaced the RT8231AGQW and made the measurements. Everything looked fine. I connected the power supply and the LED light came on for a moment. After two seconds, the short-circuit protection was activated in the power supply. I took the measurement again. It turns out there is a shorted + 19v line through the DDR and VVT power mosfet. I removed the mosfet and made a measurement - still short circuit. I tried to inject 1.2V. The circuit was drawing 6A but nothing warmed up. I used freeze to locate the damaged element. I was hoping it wasn't a CPU, but well, it's a damaged CPU after all.
Thank you for your willingness to help.
