please help how i can repair button phone dont turn on
@raw771 , Anton, Make sure battery is charged, try a different compatible charger if need be. Use the guide below to disassemble the device so you can disconnect the battery for 5 minutes,then plug back in and check/reseat all the connections to make sure all are connected well. Try and power on phone. Good luck. I hope this helped you out, if so let me know by pressing the helpful button. Asus ZenFone 2 Motherboard Replacement
Unless you have a micro soldering setup, you must either send it in for repair, get a new motherboard, or a new phone. You can, however, keep using your phone as is, just don’t ever let the battery die.
