PP3v3_G3H isn't present on charger (expected) or on battery. Both show 0.0v
Its near on impossible for me to test around U6990 on battery but on the charger I get 5.2v on D6905 pin 2 5.1v on pin 3
On D6990, I get 5.1v on pin 2 but 0.0v on pin 10 enable.
I had an A1466 in the other day that was apparently needing a replacement main board (according to another repair shop) they wanted to replace the board for ?450.. It came to me for a second opinion and turned out to be a ?5 trackpad ribbon. They were charged ?49 ($65 USD) in total by myself...
