8-3-1. Power On

Check the Battery Voltage is more than 3.7V

(TP:C109,C110,C212,C311)

Yes

PMU_VIO = 2.8V? (TP:C207, C323)

Yes

Check the Clock at UCP200 L16pin (CLK32K)=32KHZ (TP:OSC201)

Yes

+VCORE_1.25V = 1.25V?

(TP:C204, C214, L201)

Yes

Check the initial operation "Power On"

Yes

END

Change the Battery (Because of batt. power low)

No

Check the Main Chip related to VGPIO_2.8V (TP:C207, C323)

Check the Main Chip

No (TP : OSC201 / look over the waverform using the oscilloscope)

No		Resolder C204, C214 and L201
		(to confirm coming out power V_core)
