Please tell us some basic information before asking for help:

  1. Model Name: zenfone 5 ZE620KL
  2. Firmware Version: latest version
  3. Rooted or not: not rooted
  4. Frequency of Occurrence: doesn't turn on

Last night when i picked up my phone from my desk it was off. It should have had about 80% battery left. It has done this before and normally I just hold the power button and it turns on. When I tried this it showed me the "powered by android" followed by an asus logo and then a few seconds of black screen before it turns of. I tried again this morning and its doing the same, sometimes after the asus logo there is a split second of some glitching graphic and then off.

I have tried power + volume up/down, power + volume up gave me the asus logo and in the top right it said something about fast boot and to hold down the power button but the message was not fully readable because of the notch. I then turned it of but now I can't seem to do this again. It seems like it wont turn on at all after this.

The only option that i have left is to open it up and disconnect the battery.
