HP da0r13mb6e1 notebook not out of 3v5v maintenance

HP machine model: r10be1

Fault phenomenon: the notebook does not output 3v5v

Maintenance process:
HP da0r13mb6e1 notebook does not output 3v5v, you can first try to replace the stable Capacitor, and then replace the chip.The following is the rerouting process.
As the other pin definitions of rt8223 and 51125a are almost the same, only the working conditions of the 4th pin tonsel and the 14th pin skipsel are different, so it is only necessary to change the working conditions of the two pin.
Take HP da0r13mb6e1 notebook as an example.

HP da0r13mb6e1 notebook does not output 3v5v maintenance Figure 1

Compared with the 4th pin tonsel and the 14th pin skipsel, it was found that the working conditions in some places were different. The 4th pin and the 14th pin of rt8223 were disconnected from the main board.I cut it directly with a blade.
