"Replaced Battery, Constantly Reboots and unchanging battery percent"に関する回答Another cause of the boot loops Which i discovered myself, is the new batteries, wherever they come from, usually dont have a foam sticker on top of the connector. YOU MUST PUT ONE ON!! - in my case i didnt have one so covered the connector with electrical tape. Otherwise the logic board will detect interference and wont do a full POST. and hence create a boot loop. Simon
