CHG02 – No charging indication 
If display indicates “Charging not possible” or the phone powers on while plugging in the 
charger, but is not charging. Then check the USB_ID line at J1_USB-2 with phone 
powered on by battery. It should be 2, 7Vdc (2,4Vdc is not enough!) 
 
-  If not  -check VR950. USB_ID voltage must be 2,7Vdc, if VR950 is removed 
-  Check voltage at C951-1 (2,7Vdc) 
-  If ok -replace the ATLAS (U900) because the EMU-chip is in ATLAS integrated. 
Please use underfilm for U900.
