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?
