Problems[edit | edit source]

Problem	Solution
Battery will not charge or power on	could be a bad tristar chip (U2)^[2]^[3]
Powers up enough to show low battery screen when plugged in (draws 80mA), but wont hold the charge when unplugged.	might be just an old or defective battery that needs replacing could it also be something shorting out on the board?
-No charging. Pulls full amperage when the charge is plugged in (approximately 2.3 amps) then drops to zero amps when fully booted. -Disconnecting the charger while at full amperage then replugging shows zero amps. -Device automatically boots when the battery is attached (no power button press or charger prompt to boot)	This is caused by a faulty PMIC. The PMIC fails quite often on the Air 1, Air 2, and Mini 1-4 series. Replacing the PMIC corrects the issue a majority of the time.
