My laptop cannot get started and power jack output is low
The very same problem as I asked before. Now yesterday I disassembled my laptop, removed the battery, plugged in the power cord and tested the output of the power jack. I first simply plugged the power cord into source and the tested output voltage was 19V. When I plugged in the adapter, I used the multimeter to test the voltage received from the power jack, and it was about 200 mV or so, far below the 19V which was needed. Now does it mean the problem was on the power jack? And if it is, how can I fix it myself?
Is this a good question?
