Problem:This laptop motherboard is no activity while connect the adapter.mainvoltage runs only adpater connector then vanish.we crosscheck across the motherboard .no damages.no rusted.no short circuit.it seems fresh.consider to replace charging ic.avoid to inspect the jumbers settings through schematic.jumbers are damage logically. also charging problem.not reaching the battery 100% without interception.its charging 3 to 4 hour.its too longer than usual.
solution:forming a circuitary manually to flow the current everywhere.then its acivating regulator and generate the LDO for testifying .its become on state.then crosscheck the around charging ic .the diode has damage.once refix and testify.its normal eveything.
