This one won't start from battery and it won't show anything on the battery indicator. With magsafe connected it starts and charges the battery. There is no X on the battery icon. It runs from battery if magsafe is disconnected. Nothing changes if I disconnect the BIL
There is nothing wrong with the data bus if the battery is recognized fully in OSX. I doubt you checked this as the BIL does not work and there is no power from battery. Check the pull up resistors and otherwise it is dead SMC/ISL6259
When the computer is running SMBUS_SMC_BSA_SCL goes up to 3,4 volt. But when it is off it's only 1,5.
checked three other macbooks and they are all showing 3,4 when off.
dukefawks Dont understand what you meen with this "I doubt you checked this as the BIL does not work and there is no power from battery"
It works from battery but it wont start from battery.
if R5280 is normal, Bat connector looks clean, BIL change has not effect, and PPV3V42 is present... I would try replacing D6950, Zenor's can be a bit funny
This One almost work now. It boots from battery.
The problem is that the fan starts spinning before login screen. And after a few minutes the coursor is hacking and everything feels slow. When i run it without the battery its all good. I have tried different trackpads, bil-connectors and batteries with no luck.
