Lenovo Ideapad 320 series
problem: No power,
Process of Troubleshooting
Check adapter and a charging connector
check all the coil if it is shorted but all coil is good
using Regulated Powersupply Check voltage on 19v power rail
19v is not presented,so backward check if were is the 19v power rail stop then I seen that Switching IC is cut off the voltage..
check using multi tester to prove if it is open or not by pointing continuity on tester.
remove the Switching IC then replace or jumper the tiny wire.

done:
