        yes, it is possible to make such a jumper. it will generate 3.3v/5v only if the circuit is not faulty. Since the trace got broken, the controller IC may be probably faulty.

              there is no way to bypass the 3.3v/5v IC on a laptop mainboard. you have to fix it.

                  Jumping Vin from another source to the 3.3v/5v IC is really risky and can probably lead to damage to the mainboard.

                        No VIN in charging IC? Are you saying no reading on PU4404 pin No. 20?

                        If yes then check PU4201 & PU4402 Mosfet. First check shorting with ground and later measure voltage on all those pins and let us know.
                        Always ask with clear and more information that we can understand.
