In the event of charging issues, check charging voltages along the charging path: ● Check the battery is inserted the CON1002 or not ● Check battery ID voltage at TP1006 about 1V ● Check thermistor voltage at TP1005 about 0.63V ● Measure USB_PWR charger input voltage at TP1004. The voltage should be between 4.75V~5.25V.

● Measure VCHG voltage at C1012. The voltage should be lower the USB_PWR.

● Check battery voltage at CON1002 pin4. It should be 4.35V or lower. If battery is 2.1 or 0, there maybe a short in the circuit somewhere. The battery fault safe circuit is triggered.

– Check if the other functionality fails as well, e.g. check WLAN “power on” if Bluetooth can not be powered on. Check Bluetooth “power on” if WLAN can not be powered on.

– Both WLAN and Bluetooth share the same IC and most of the circuit, so if one of the BT/Wi-Fi fails, the other should fail as well. If only one of them fails, it is highly likely that it is not a hardware problem and it could just that the BT/Wi-Fi is turned on through the UI already and the test commands can not turn it on again.

– If there is no visible sign of antenna damage and antenna contacts damage, its most likely something wrong in the BT/Wi-Fi chips or circuits. – Look for misplaced or damaged RF front-end components. Please refer to the previous slide describing the layout of the WLAN circuit. – It is recommended to probe the amplitude of the TX signal along the RF path to look for the failure component.
