Suggestions;

Anti-Static wrist strap connected to ground source, and your wrist;

1) The jack your AC adapter plugs into on the motherboard, is the DC Power Jack.
Motherboard out of case, power to motherboard, take your multimeter and see if you are getting 19 VDC at the DC Power Jack's positive solder joint, on motherboard.

The center pin of the jack is Positive. (The inner cylindrical shell is Negative)
Follow the DC Power Jack's positive pin from the Center of the jack, to the motherboard.

You probably won't be able to touch your meter's Positive (Red) probe, to the DC Power Jack's positive pin under the jack; so touch it's solder joint on the opposite side of the motherboard.
(DC Power Jack should be soldered close to the motherboard, is why)

Of course also touch the Negative lead, (Black probe), of your meter, to the Negative, (Ground) solder joint for the DC Power Jack.

Getting 19 volts DC?

See if there is a cracked solder joint, for any of the DC Power Jack's pin connections to the motherboard.
ANY perceptible movement of the DC Power Jack on the motherboard, indicates a bad power jack, and may indicate a broken/cracked solder joint.
Center pin of DC Power Jack is loose? Bad DC Power Jack. Replace.

2) DC Power Jack is determined to be in good repair? No cracked/broken solder joints?
The next components in the power circuit on the motherboard, leading From the power jack, are P. MOSFET's.
Power MOSFET.

Check the links given.

3) The last thing that concerns me, although I probably should have listed it first; is the AC adapter you are using.
Concern is that it doesn't have the 'intelligent chipset' that matches the Compaq CQ1-1225 All-In-One desktop PC's circuitry.

Which ac do when a laptop compaq nc6400 is verr slow and doesnt charge the battery


What does the AC do? (Alternating Current)

Apparently not get rectified into DC electricity by the AC adapter, (Charger), or the rectified AC (Which is now DC), is not getting to the laptop.

Be sure the Battery is still good. They have a lifespan, and only last so long.

Verify, by performing a DC Voltage test with a multimeter, if the AC adapter is putting out the correct Voltage.

If it is an AC adapter for an HP Compaq NC6400 Notebook PC, the DC Voltage coming out of the AC adapter is supposed to be
18.5 Volts. (DC),

http://www.amazon.com/Notebook-Adapter-Presario-cq50-142us-cq50-110/dp/B001MQ4MNW

On the AC adapter plug going to the laptop, the center pin is the Positive connection.
The outer cylindrical metal shell is the Negative connection.

AC adapter puts out 18.5 Volts?
Have an assistant;

1) Gently wiggle the power cord coming TO the AC adapter.

2) Gently wiggle the cable coming FROM the AC adapter TO the laptop.

See if you get an intermittent reading on the multimeter. Indicates a broken wire.

[ An economical, but fine for this test, multimeter, can be purchased for as little as $8 to $12, here in the US.
Analog or digital is fine.
Available in a multitude of stores. An auto parts store is but one example ]

AC adapter checks out it's on to the DC Power Jack.
This jack is the round port on the laptop, that the plug from the AC adapter plugs into.

Battery removed use a wooden small object, and gently see if you can move the center pin around, for the DC Power Jack.

See if the rest of the DC Power Jack will move around.
ANY perceptible movement means a problem with the DC Power Jack.

The DC Power Jack looks like this not mounted to the motherboard,

http://www.batterystyle.com/compaq-nc6400-jack-p-436629.html

Click on the two views shown of the DC Power Jack.
The view on the left shows the jack from the back.
The view on the right shows the jack from the front. The view you see now.

Note that in both views the jack is shown upside down, in relation to how it actually sits on the motherboard.

The view on the left, (Back view), shows Prongs coming from the jack, that go down through the motherboard, and are then soldered.

The gold colored prong is the Positive prong. It goes to the Center Pin of the jack.
All of the silvery colored Prongs are for Ground, or Negative.

Where the Prongs are soldered to the motherboard, are called solder joints. Each prong has a solder joint.

It may just be that one, or more solder joints are cracked.
This would require disassembling the laptop down to the bare motherboard in your hand, then re -soldering any cracked solder joints.

[ Be SURE to use an ESD wrist strap, and have it's alligator clip connected to a good ground source, BEFORE working inside a laptop ]

It may be however that the DC Power Jack is damaged, and replacement is necessary.

Need guidance in de-soldering, and removing the old DC Power Jack, and soldering in a new one?
Post in a Comment.

If the DC Power Jack checks out, you have a bad power correcting chipset. This is a type of Power MOSFET.
Motherboard replacement is the solution.

My M2000 will not power up, have new battery and charger but still no power.


The DC jack in the laptop is often source of trouble, but the computer must be dismantled down to the motherboard level, at this point I recommend a professional to assess the repair cost.

My HP Compaq 5325 suddenly went off and now won't power up. No lights showing at all. Removed battery, plugged in mains but still the same - no lights. Can anyone suggest what it might be? thanks


The problem may be the DC jack in the laptop or a bad power supply. If you can confirm the power adapter is okay by testing or subbing another power unit then I will assume it is okay and go to the next step. Plug your supply into the laptop, now put your hand on the DC plug and apply pressure sideways with the thumb "not to hard" at the same time press the power switch repeatedly to see if it will start, if yes! the DC jack needs to be resold-ed back on the motherboard or replaced. If still no change this is where a computer technician will be needed to go further.

DC Power jack heats up to very hot to touch on HP NX9010 laptop.


The DC jack, where you plug the power adapter cable, might be loose or defective, & needs to be either re-soldered or replaced.
In order to do this, the laptop needs to be disassembled & the motherboard taken out. Also, the motherboard needs to be checked for defective/burned out components in the area near the DC jack. Any defective/burned out components found should be replaced, or you might need to replace the laptop's motherboard altogether.

My hp compaq nx9010 wont power up. dc supply is good and the batteries are ok. No led light...


This is a typical symptom of motherboard failure. Your laptop's motherboard will need to either be serviced or replaced.

Has no power


check your DC Jack on the back where electricity is plugged in to the laptop-

Maybe a bad connection.
With Thumb- push the jack to the left and press power button. If this doesn't work, Also try pushing to right, and trying the power button. If you get lights, or it powers on that verifies that you have a DC jack issue.

Do not attempt to use by holding it or using duct tape, get it repaired. If you attempt to use by holding or taping you will further damage the contacts around the jack internally and render the motherboard unrepairable-requiring replacement. This is only a test verification method.

The cost of DC Jack repair/reflow is $50- 100 depending on your area/region.

Try local first before mailing off your laptop!
