If your Samsung AD-12019 AC adapter hasn’t been working properly you can test it to see whether it is dying or dead. This process does require special equipment, but there is no disassembly of the adapter involved. The process should only take a few minutes, regardless of how much you know about electronics.

Instructions

1 Unplug your Samsung AD-12019 AC adapter from the computer as well as the power outlet. Place it on a sturdy work surface.

2 Insert the tip of the voltmeter needle into the end of the Samsung AD-12019 adapter plug until it won’t go any further.

3 Press the “Power” button on your voltmeter and switch it to volt mode. This is identified by a “V” icon on the meter on most models.

4 Wait for the voltmeter to display the voltage on the display screen. Somewhere around 15 volts is good for a computer adapter while, naturally, a reading of zero volts means the adapter is dead.
