Laptop works either on AC adapter or on battery but does not charge. The LED turns amber after connecting AC adapter, OS says "charging" but there's no current flow to the battery.
Tested 3 adapters (original 135W, older 90W and 60W), two batteries (both do charge on bench supply and provide correct data through SMBUS).
Charger is ISL9241, MOSFETs are OK. There's SMBUS communication between EC (IT8987VG) and charger. Examined SMBUS using analyzer - seems that EC does not enable charging
Upgraded BIOS to latest (47), EC was flashed too during the process.
Any ideas?
