820-2850 just like the other ones i have on resent topic. was dropping voltage on ppbus, i fix the voltage drop by replacing the isl, i had solid voltage on ppbus and a solid voltage on r7020 i plugged in the battery to test if it would charge nothing charged, unplugged it tested my ppbus and r7020 and the voltage was dropping again.. is there anything specific the battery would kill to cause this? still trying to find what went out but have not found it yet, tried swapping the isl out with a known good one, replaced the c7035 36 37, Q7030 and 35, and c7005 r7005, also checked chrg ACIN and getting 4.4v there. checked q7085 also good. rather annoying that ppbus keeps going out
