I tried to start the computer and noticed that presents a reasonable heating near the PWM (PU9 MAX17020) probably it. PL13 removed the coil and the almost short or very low resistance from the PC159 capacitor. You are having a problem 3.3volts voltage line. What could I verify or test? Posted after 2 hours 31 minute: removed the PL 13 coil and applied a 3.3v voltage in PC159 capacitor terminals. Then I noticed normal heating north bridge but near the welded components in PQ45 board, U30, U27 showed a slight warming in the first instant. If I let the PL13 welded coil in place and turn on the notebook happens abnormal heating of PU9 |
