The C7001 board is fine, the R5280 board still has problems detecting the battery, and the board I started the topic about still isn't showing anything good--I think it's a bad ISL chips, but I don't have any good ones here to test. I should be getting some soon tho.
Still need help on that low voltage on the SDA side of R5280--that SDA line is showing ~1.5v everywhere on the board. What do you think, ISL?

Check resistance to ground on SCL/SDA lines.
You must get less than 1% difference.
If bad reading, disconnect BIL, remove D6950, C6952/53.
If still bad, pull out ISL6259.
Then will only remain SMC on that bus...
