Analysis
The G510 adopts the independent power management chip PM8029. The PM8029's power-on
process is controlled by Qualcomm's codes. When the PM8029 detects that the
KPD_PWR_ON level is low, the PM8029 enables the power-on process. During the power-on
process, the PM8029 converts the main power supply voltage (VHP-PWR) to voltages shown
in Figure 9-3.
