Clean board, works most of the time, when it doesn't work there is no light on the charger or sometimes it only shows green light but battery is disconnected or not fully charged.
I replaced U7100 and worked for a day but it is back to the same problem now.
Thanks, however when the problem happens (no light at all or only green light on charger) the MacBook Air doesn't turn on, if I connect and disconnect the charger multiple times nothing happens either and no power, if I remove the board from the case and test sometimes it works fine but suddenly it will stop working with same symptoms.
In case someone new like me wonders what MLB is I think it is Main Logic Board, LIO board is where the charger connects, LIO flex is the flex cable that connects to the MLB and LIO board.
I know to some this is obvious but for newbies it is not.
