Computer Laptop Repair #8 Samsung NP Series Lost The Power
The problem of this samsung laptop is lost the power of adapter supply. Even adapter plugged into the jack power there is nothing to detected. I have checked the adaptor power supply it's good. But when plug into the jack there's some problem, the voltage is down in my test meter.
The component I check is mosfet P-Channel. It is placed after jack power.
It should be, the voltage on both pictures are 19v.
If we don't check we will not find the problems, because it is not shorted component.
So, what have todo???
This part is needed to replace with good one.
We need the hot air tool.
Release it and replace with new.
This is the broken part, it was shorted.
After replace I try to running test
And ..... Taadaaaaa....
Problem solved..
If you need full process, just watch my video! I record it when I am repairing the laptop.
