i've got this 820-3462 here that originally did not recognize the battery after liquid damage. After trying a different battery no more green light on charger. checked pp3v42 is present but no CHGR_ACOK. Checked U7000 for CHGR_ACIN, CHGR_CIN, SMC_RESET_L, PP5V1_CHGR_VDD all are present with no short to ground on CHGR_ACOK. Im guessing some how the untested battery i plugged in may have cooked the U7000 somehow.

any suggestions?

is there anything that can be done about this machine failing the ASD for memory errors? It boots in to OS X and seems to run just fine.
