Question about HP Compaq nc6120 Notebook

2 Answers

I have a compaq nc6120 laptop. The power cord where you plug it into the computer has a small hole that goes around a pin. That pin broke off the computer and is in the power cord. I can easily pull it out of the power cord, but don't know what is recomended from that point. Do I need to replace that part, or can you solder the thing together completely. I don't need to transport this laptop, so if it were permanently connected I would't care. Looking for suggestions?

To be safe i would definitely buy a new ac adapter. go to ebay and just buy a generic replacement so you don't have to spend a lot of money.

The adapter light is on when first plugged in but then when I connect the adapter to my laptop the light goes off and it doesnt supply any power


I suggest check out the AC adapter first.

1) When plugged into power, and plugged into the laptop, gently wiggle the cable from the AC adapter TO laptop.

Any change?

Do the same on the power cord TO AC adapter.

NO?
Go on.

2) The port on the laptop that the plug from the AC adapter plugs into, is the DC Power Jack.
If we are discussing an Acer Aspire 5738Z Notebook PC, the DC Power Jack resembles this one, (Not installed),

http://www.batterysupport.com/acer-aspire-5738-jack-p-302046.html

(When I note the DC Power Jack, it is this link I will be referring to )

As you can see there is a Center Pin. All power removed from the laptop, use a small wooden, or plastic object, and see if this pin moves around.

ANY perceptible movement means a bad DC Power Jack.

DC Power Jack checks out it's back to the AC adapter.
Wanted to perform the easy diagnosis first.

This will require a multimeter. An economical, yet fine for this test multimeter, can be purchased for as little as $8 to $12.

Available in a multitude of stores. An auto parts store is but one example.
Analog or digital is fine.

http://www.youtube.com/watch?v=bF3OyQ3HwfU

(Analog is fine. Some of us still like 'em)

DC Voltage is what you are going to check.

Black probe lead (Negative) goes in the Common port on the multimeter. (COM)
Red probe lead (Positive) goes in the Voltage port on the multimeter. (V)

If the multimeter just has symbols around the Function Knob, set it to the dotted line over a solid line, symbol.

The plug on the end of the AC adapter, that plugs into the laptop, has a center hole, and a cylindrical metal shield surrounding it.

The Center Hole of the plug is where the red Positive lead, of the multimeter goes.

The outside cylindrical metal shell is where the black Negative lead of the multimeter goes.

Hold the AC adapter plug in one hand, and at the same time hold the red Positive multimeter probe in the center hole.

With the other hand touch the black Negative lead of the multimeter, to the cylindrical metal shield on the outside of the plug.

You should read 19 Volts (DC), or VERY close to it,

I believe the AC adapter is the problem. Post back in a Comment as to your findings.

My hp laplaptop error power surge on hub what do i do?


you'll have to provide more details about the problem. From what little you've said, I suppose your laptop wont turn on both when trying it on battery and on power cord. If this is the case, you may be facing the well known Maxim chip problem. he nc6xxx series are known to have these problems with the Maxim chip and the power plug on the motherboard. You can find the Maxim chip and power plug resolder instructions here.

Battery charger


Yes. Usually they either work or they don't so obviously when they test good they should charge the battery. Dell laptops have a "data pin" that determines what wattage of power cord is plugged. If this data pin goes bad on the power cord or motherboard the laptop won't charge.

I hav a hp nx6120 but doesnt switch and wen you plug in the charger its no lighting


Take a look at the back of the laptop. Is the gold power pin still there or is it now stuck in in the end of the power brick cord?

HP actually extended the wty on these machines because of the
power pin issues. If the power pin is missing you will need to have the machine serviced. Out of wty, replacement power pins are easy to solder on the board if this is the issue.

If your pin is still there... Your AC cord or power brick may be the next things to check. Connecting them to a meter will tell you if there is power. Try moving the cords to check for shorts in the wires.

If your AC cord and brick are good, try pulling the battery. Your laptop can run off AC only. Batteries with bad cells can sometimes prevent the machine from powering up.

If its still not powering up after all of that, there may be an issue with the motherboard in the machine.

The pin in the middle of the power cord input has come out


unfortunately that is an impossible fix...
the only real way to do is complete replacement of internal charging device, which, depending on the laptop, may be cheaper just to go get a new one

The pin that the power cord goes into has broken off


Is the cord broken in the computer, or the monitor or the pin broken and stuck in the machine? If it is in a desktop it goes into the power supply. Which you can change the whole power supply fairly cheap. that is if it in a desk top computer. 4 screws, 4 or 5 connectors and ta da new power supply, All you need is readings off power supply such as wattage. Good luck
