3.2 Visual check.
Make a visual check. Make sure that the battery screws are intact and properly
mounted, that the isolator sleeve (GH 688) is properly mounted, that the volume
keys aren’t stuck and that the system connector isn’t dirty or liquid damaged. Con-
tinue at 3.3.
3.3 Current consumption with On/off-key
pressed.
Insert a dummy battery.
• If the phone consumes current immediately it usually means that C403 (class A,
fig. 3.3) is faulty but first you should make sure that the frame gasket isn’t in con-
tact with the positive battery connector pad at the circuit board (fig. 3.4).
