    Lenovo BIUS4/S5,CIUY0/Y1 LA-E221P Rev: 1.0 IdeaPad Flex 4-1580

    Hi,
    anyone got the schematic and boardview for this device?

    Strange charging behavour, charges battery only above certain temparature, otherwise doesn't even recognize AC Adapter. Unplug the battery and it always runs on AC, even if it's cold.

    Charging IC is ISL88739HRZ, heard about issues with a resistor around.

    Thanks in advance!
    BR, Ray
