hey guys,

this one won't charge! No liquid damage and no one touch before me!

Already replace U7000 for a new one but without changes!

in osx i can see the icon of battery change some time. Some times i have a X and some times i get he thunder as it was charging!

And in "system report > Energy" i have the message: Error on getting information.

already try a good Battery no hanges.

In diode mode on SMBUS_SMC_BSA_SCL - 0.461v
SMBUS_SMC_BSA_SDA - 0.461v

any help with tis one?

thanks

R6950 it's ok and i'm sure to have contacts on j6950!

SCL/SDA voltages Float - 3.417V to ~ 3.314V some times 2.9V

R5280/1 = OK!

PP3V42_G3H it's stable!

SCL/SDA lines should pulse, is normal when have activity.
Is better to check with o-scope.
Change SMC, if you are sure no battery issue.
