    thinkpad x1 carbon 7thgeneration

    hi everyone
    charging ic is faulty and short on regn pin
    ic number is bq25700a but its not on the market here
    i cant find any interchangable one
    is there any equivalent for this ic?
    second question: i dont have a type-c charger now
    will the system turn on if i inject 20 volts after changing charging ic?
    thank you all
