    Hello! Platform: 820-2530a

    The notebook came after another service. Everything works expect battery detect - "X" in mac OS, and no charge, magsafe always bright green.
    Also the LED battery measurement bar doesn't work.

    Now i disconnect battery, LED bar, and only plug Magsafe.
    Resistance between SMB_BSA_CLK, SMB_BSA_DATA to GND = 13 kOhm,
    Voltage 3.4v both. R5280, R5280 = 2kOhm both. Also i blowed off D6950.

    i've just checked SCL SDA with oscilloscope!

    I see SCL signals, but nothing from SDA, only permanent 3.4v. Battery now show in Mac OS as 0%, and if i go to system preferences - power properties - the error occurs during collecting data.

    I think there is fault in SMC SDA line, don't you think?

    I think you should simply take it in to Apple again.
