We have the same problem. Have reinstalled from scratch, updated the BIOS and other drivers from the HP site etc.

Even bought a new battery and charger as it seemed to be related.

Have seen a response on another thread that the problem is overheating causing the CPU to down-clock. But not sure what I can do about that :(

Sounds like you have too many running processes and startup programs.If its not charging, the battery itself may be bad or the charger board is bad.The ac adapter you have may be too low voltage.Your slow running system could be a hint of a future HDD failure or ram thats running a bit to hot,which is what will eventually seize the HDD

Firstly you have to do a locally or remotly backup of all your documents cause in this process you may loose some of your vital document. Check to see if your Operating System (OS) is up to date. Or you can do a Restore if you have creat One. Its a Software issue and once you Re-install your Operating stsrem all will be fine.

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.

T will indicate charging but it won't charge actor


If the laptop works only off the Power Cord and the batteryis not charging, then the battery is dead.

To check to make sure the Power Cord is working remove the battery and let thelatop run for 10 minutes or so.

To check to see if the battery has any charge left in it put the battery in andremove the power cord. If it won't boot or shuts down then the battery is deadand needs to be replaced if the power cord is ok.

Compaq hp 6400 fake charging


The battery is totally dead. If you are able to use your laptop with the power cord, but not with the battery or only for a very short time with the battery because it will not charge, then you need to replace the battery.
