This solution shows the connection line path of the power ON and OFF button switch of Nokia E51. This may help also for lifted power switch button on the PCB board and can be used to reconnect it again.
Refer to the solution below to determine its connection line paths and connected components. In some cases like power switch terminal solder pads is lifted or the capacitor and resistor already been missing, you may need to use a microscope and sharp blade knife, then dig out the PCB layer where the capacitor or the resistor conductive connection and then manage to establish a solder connection on that spots.
If the above procedure failed you can directly apply a tiny magnetic jumper wire through to the power IC (AVILMA). However, this troubleshooting needs a good soldering skills because the power ON/OFF switch connection is connected directly to the power IC's solder ball bump number D9. Do not attempt to do it if your not good enough into soldering techniques. So Good Luck..
