Under normal circumstances, when pressing the power button, the voltage of the trigger end of the power button should change significantly, if there is no change, it is generally due to poor contact of the power button or broken power line, virtual welding of components, and damage and rolling branches. When repairing, use an external power supply to supply power, observe the change of the ammeter, if the ammeter does not respond, it is generally a disconnection of the power line or a bad power button.

For most mobile phones, after the mobile phone is added to the battery or external power supply, the power supply voltage of Daduan Min is directly added to the power supply C, if the power supply voltage is not added to the power supply IC, the mobile phone cannot be turned on. For Motorola series mobile phones (except Motorola T2688), the power supply is different, and the battery power supply and external power supply must be converted by electronic switch and then added to the power supply IC. In other words, there are two paths to the power supply of the mobile phone, one is battery power; The other is powered by an external interface (when powered by a charging dock).

When two power supplies are supplied at the same time, the external interface is given priority. The switching of these two power supplies is controlled by the electronic switch tube, which mainly protects the current of the whole machine and prevents damage to the integrated circuit inside the mobile phone due to short circuit or leakage. However, if the electronic switch is damaged, the source module may not get the power supply voltage of the battery, causing the mobile phone not to turn on.

It may be caused by software incompatibility, the backup data is double-cleared, or it may be covered by the sensor.
