Thanks for your reply. Could you please let me know which voltages or signals I should measure and at which test points or pins? That would help me narrow down the problem. (For example, ACDET = 14v)...

The device is not charging with the 19V 180W DC charger. If the battery is full, the laptop powers on normally. I can charge it via USB Type-C, but it’s very slow. I checked the schematics but couldn’t find a solution. I even replaced the BQ24800 battery charging IC, but the issue remains the same. I suspect a MOSFET or a fuse that I might be overlooking is preventing it from charging with the adapter. Has anyone experienced a similar fault before or has any advice?...
