    Welcome to Android Central! Have you actually tried a new or different battery?

    I assume you fully charged the new battery, correct? Have you tried pressing and holding Power for at least 15-20 seconds? If that doesn't do anything, then it's possible that either the Power button is faulty, or the motherboard has failed. You'd need to bring it to a repair shop to fix it.

    Tried on my Ascend G7 which unable to replace battery myself.
    IF you are stuck at BOOT & RESCUE MODE screen, and you are locked, just HOLD power button for around 1 minute( mine worked for 40 seconds) until it turns off, then turn it on again as normal.
    This fixed my led blinking problem and how to turn it off if stuck in rescue mode.
