Often traced to the DC-in jack or the primary MOSFETs near the battery charging IC. brittle mb 15256-1 boardview

for "dry solder" or broken terminals. If the jack is fine, the search shifts to shorted capacitors or a faulty Charging IC (which may feel hot to the touch). Backlight but No Image Operates on a standard 19V–19

The BGA (Ball Grid Array) solder used on the PCH (Platform Controller Hub) and Vcore power management ICs is unusually hard. While hard solder is good for thermal conductivity, it does not tolerate board flex. Consequently, using the boardview to trace open lines often leads to a “phantom open”—a net that shows continuity on the file but is physically broken under a component. If the jack is fine, the search shifts
