Title
Lenovo K80M No power source or Off during boot
Introduction
Lenovo K80M does not turn on suddenly.
Rom : Android 4.4 Lenovo genuine.
No rooting history.
There is enough battery, the phone is turned off from the Android logo during boot.
The battery is normal, but the battery protection circuit attached to the battery is judged to have failed.
When power is supplied directly to the unit, it turns on normally.
However, the external power is supplied through the protection circuit
Does not work when power is input.
Using a battery with a battery protection circuit
When connected, it works normally. (It does not matter)
Do not replace the battery only because the protection circuit can not be used due to the failure of the built-in protection circuit. (To prevent danger even in case)
I plan to connect the 18650 battery to the phone and recycle it only to the game and car navigation.
