Step by step

  1. 30 min

    Perform a deep charge

    Connect your device to a verified wall outlet using a known-working power adapter and charging cable. Leave the device undisturbed for at least 30 minutes to allow a depleted battery to reach a charge state sufficient for booting. Avoid using computer USB ports, which provide lower wattage and may not supply enough power to wake a dead battery.

    Note: Check the charging port for debris or lint using a non-conductive toothpick before plugging in the cable.

    Execute a forced restart

    If the screen remains black, press and hold the Power button simultaneously with the Volume Down button for 15 to 30 seconds. This hardware-level command bypasses the operating system to force a full reboot. Release the buttons only when the manufacturer logo appears on the screen.

    Note: Some models may require holding only the Power button for up to 60 seconds.

    Isolate hardware accessories

    Remove any protective cases, screen protectors, or external attachments that may be obstructing buttons or sensors. If the device was previously dropped or exposed to liquid, inspect the exterior for physical chassis damage or moisture indicators in the charging port. External pressure on the chassis can cause internal shorts that prevent startup.

  4. 2 min

    Access the recovery menu

    While the device is off, hold the Volume Down button and press the Power button to boot into the Fastboot or Bootloader mode. If this menu appears, the hardware is functional and the issue is likely within the Android operating system. Use the volume keys to navigate to the Power Off or Restart option to attempt a normal boot.

    Note: Do not select 'Wipe Data/Factory Reset' unless you have a recent cloud backup.

    Examine for heat and vibration

    Plug the device back into power and check for subtle signs of life, such as a vibration, an LED indicator light, or an increase in temperature on the rear casing. If the device emits heat or vibrations but the display remains black, the issue is likely a failed internal display panel rather than a power failure.

    Note: A black screen with haptic feedback indicates the phone is on but the display driver or component has failed.
