The first step:

The first step:

Open the back cover and remove the battery

The second step:

Plug in the charger, wait for the charging screen to appear, decisively press and hold the power button to turn it on. Note that there is no battery in the phone.

Third step:

After the boot is successful, install the battery and the back cover, OK, you are done.

Simply this could solved in 1-2 minutes. This is a small problem but it might cost you high if you ask mobile phone repair shop to fix for you. I remember I was very upset when first met this situation and it took me quite long time to work this out. This is much easier and convenience compare not using phone for a few days or use Multi-purpose battery charger as someone suggest. I think it is a happy thing if we could find these problems and solve them by ourselves.
