Either with the position of the battery installed or just the adapter without the battery also can not be turned on. The motherboard has been uncovered from the casing.
I try to check by using multitester, as a result there are some components that have been damaged and must be replaced.
3 problematic components are p-channel mosfet, n-channel mosfet and 330uf / 3.2v smd capasitor. See picture of the following components.
Pay attention to the position of the location of the problematic component

Of course to determine the problematic components should already have knowledge about electronic components and how the measurement.
Most beginners only suspect the expected damage to the component, finally another problem also sought the solution. Steps should be, study the problem, detect the problem and find the best solution to solve the problem.
A definite experience is our best teacher. I learned from many mistakes and tried to make mistakes.
Good luck and always successful.
