Remove the battery and start the laptop from the adapter. Should I even then disassemble my D610 and check the DC IN port? If the battery stops charging when you move the adapter plug, test the AC adapter first. In some models the DC jack is soldered to the motherboard. The DC jack harness is defective and had to be replaced and the new one fixed the problem. When the adapter cord didn’t move, I was reading 15.45VDC.īut as soon as I started wiggle it, the voltage dropped to 0VDC. In my case the DC jack was attached to a cable and I easily disconnected it from the motherboard. I tested it with the voltmeter as it shown on the following picture.
You can find disassembly instructions for most laptops in their service manuals. In order to access the jack I had to disassemble the laptop and remove the top cover assembly with the display. The next step was the DC jack inside the laptop. It helped me to make a conlcusion that there is nothing wrong with the adapter connector or cord and most likely there is a problem with with the power socket inside the laptop.
The power didn’t cut off no matter how badly I wiggled the cord.
If you have a problem like that, most likely it’s related to the AC power adapter or the DC jack.įirst of all, I tested the adapter with a voltmeter. It turns on and runs properly from the AC adapter but as soon as I start moving the connector inside the jack the laptop shuts off and it loses power immediately. First of all, I tested the laptop with the battery removed.
