Hi, I agree with not firmware. It's something to do with usb extension(self powered) and having external hard drive (self powered). It's doing it again. I don't know if it's feature or bug but battery is at 87% and no longer charging. 35564 mWh /40604 mWh. If i take hard drive off usb extension and reconnect power it start charging again to 100%.
Anyone has come across this issue?
