    volcano_c,

     

    That seems odd that every battery you use would not be able to charge again. It does not sound like a battery issue to me and possibly a charger issue. When the system is powered off, do you see a power and battery light illuminate?

     

    If you do, but do not see it when the system, is powered on that does lead to believe that the charging adapter itself may be bad.

    volcano_c,

     

    I am not aware of any battery firmware published from Acer.

     

    When the system is powered off, do you see a power and battery light illuminate?

    volcano_c,

     

    The battery light is blinking while it is powered off and plugged in? I cannot help but think that it is not a battery problem since you are on multiple batteries now, it has to be something else hardware wise that may require a look at by the repair depot. Smiley Frustrated
