How do i Test a power jack with multimeter?
I need specific information on how to use a multimeter to test power on a HP DV6500 Laptop power jack.
I have opened the laptop.
I have a multimeter with many settings.
What settings Do i need to have multimeter on?
Where do I place the multimeter prongs?
What "reading" will tell me it is working okay?
Thank you,

ok. it's likely that the dc in jack is faulty (the only way it can fault is if it's connection to the mainboard is severed (via dry solder joints or a proken pin).
If the dc in jack is not faulty, then the power regulation circuitry could be the problem. In which case, you'd have yourself a faulty mainboard.
Either situation, you will unfortunately get access to the mainboard.
What is the product number (P/N) of your laptop, I will try to find you a service manual.

when i plug the laptop power jack, the ring led comes on. So possibly bad motherboard?

it may be slightly different for your model, but i think this manual covers all of the DV6500/6600/6700 variants.
It is looking to be mainboard

If you want to test the output of your laptop power supply look at the transformer and see if there is an output voltage printed on it somewhere it should have an input of 220-110 VAC and the output should be in VDC. Look to see the plug orientation. It should show pos or neg in the inside or outside of the plug. One you see how the plug is set up set your voltmeter for DC and in the range of your adapter put the neg lead on the neg side of the plug and pos on the pos on the pos side and you should get a reading close to the output printed on the transformer. This will tell you if your cord is putting out the correct voltage.
for most it is between18.5 and 20 V

Thank you for the settings, but I am unable to touch anything from the inside, may need to take out the whole board, and perhaps touch connectors at the bottom.
This laptop will not power on.
I have tried another charger, taken out the battery (don't have another battery), but it will not power on.
