    a1466 820-00165 power on

    hello
    I have this macair for repair which has a weird problem. The laptop does not power on the second time on battery though the battery is fully charged so i noticed one thing when i dont login in into the macos and do shutdown it power back with no issue but if i login and shutdown and then try to power the machine it doen no power back either i disconnect and reconnect the battery or i attach the adapter and then power.The battery is perfectly fine it charges well ,it is only when i login and do a shutdown in the os that the time no power on in battery mode.,if i com ein login page and dont login and do a shutdown then then it powers on.i have also reloaded the mac os and changed the ssd .
    any ideas
    thanks

    yes i have already flashed a new bios also.
    It is really strange the battery is charged 78% if i come to the login page i can shutdown how many ever times and it will power on but the moment i get into windows and shutdown and try to power on it does not happen.
