There is about one fallen notebook. the fall was not so bad at all.

Have tried :

remove the 2032 and 1 minute power button. the battery is about 3 volts. Reinsert it and with or without notebook battery absolutely no LED indications.

Have measured the voltage after the plug port and it`s good everywhere.

Have reinsert the cable between power board and motherboard and still nothing.

In technics what compont (like resistor diode etc ) is going failed after device falling on earth

Could you give me directions kind from to to fix this situation ?

thanks.

 

Broken contact
Broken PCB trace
Broken chip internal bond
etc
etc

May or may not be visible, many possibilities

Without schematics and a good knowledge of troubleshooting techniques may be impossible to locate fault(s).

That's a nearly impossible DIY job. Even if you managed to locate and replace some defective components, you have no way to exercise 100% of the logic to make sure there are no other problems.

With a laptop, you don't even have a way to monitor power on self test (POST).
