Testing dc jack on laptop

Question with testing dc jack on my Compaq Presario V2000. I have it apart now, think I can avoid unassembly of the motherboard, fan, etc, by prying up the corner case just enough to get iron in.
It is still in circuit, no matter how I ohm it, it shows shorted with pos. & neg. dont know if I'm not doing something right or what. Battery I beleive to be dead, so could not test that to see if it powered up.
The jack is not loose, one or two joints may or may not be cold, but am curious if there is a sure fire way of testing the jack to find out for sure.
Also, how important is it for reassembly to try the power?
Thanks. Bob RMo8235376@aol.com

You are not supposed to get a short on the power you could take out the power socket and try the test straight to the board.


On a board I have that works using my digital meter on the diode setting I get a reading of 1200 aprox and 190 aprox when the probs are reversed.

If you have a dead short and the power socket is ok then likely there is a resister shorted out or a diode or even a transistor chip on the mainboard.

It should be ok to power up while in bits so long as the cpu fan is running.

Good luck Regards Wayne.

Dc jack is not working, can I still use a docking


I have seen this problem with many laptops.
What has happened is that the power connector on the laptop has loose solder connections and will not trasfer the power through the jack. Either the jack needs to be resoldered on the motherboard or replaced. This is a very intense repair, because the motherboard has to be removed for the repair.

I hope this information allows you to resolve this issue.
If you need further assistance please comment to this post and I will try to help you further.

The prong where I plug in my battery charger broke off in my laptop. What can I do?


This is the DC Power Jack. Aslo known as the DC-IN jack.

You'll have to have it replaced.

IF, this is a reference to a Compaq Presario V2000 Series Notebook PC, (The exact Model Number, is on the bottom of the laptop in a white Service Tag),
the DC Power Jack is soldered directly to the motherboard.

The DC Power jack resembles this one,

http://www.laptopjacks.com/view_part/Compaq-Presario-laptop-power-jack-CQ21325.html

[At the top of the page you can click on the multiview (Three views shown), to enlarge it]

You can see the size of the jack. Not much larger than the AC adapter,
(Charger), plug.
The rectangular dark body of the jack is made of plastic. The metal center pin is riveted to the body.

This is the Maintenance and Service Guide, (Really a Service Manual), for the Compaq Presario V2000 Series Notebook PC's,

http://h10025.www1.hp.com/ewfrf/wc/manualCategory?lc=en&dlc=en&cc=us&lang=en&product=500508&

It's a download page for the Maintenance and Service Guide, from HP Support. (As you know HP bought out Compaq)

Left-click on -
Compaq Presario v2000 Notebook PC, HP Pavilion dv1000 Notebook PC, HP Compaq nx4800 Notebook PC - Maintenance and Service Guide

(Last file in the list)

This is a PDF file. (The computer you are using now has Adobe Reader on it, which uses PDF files)

After you click on the link it may take up to 24 seconds to see the first page. The file is downloading in the background.
(First page usually comes up faster)

After you see the first page, the file may still be downloading. (Blue download progress bar)
I advise letting it fully download, before looking through it.
You may break the download connection otherwise.

This shows you the inside of your laptop. Shows you how various components are removed, and installed.

[Tells you about Static, and how it's harmful to your computer, therefore before diassembling the computer, you should take appropriate measures. ESD wrist s-trap. Price is around $6]

Included this file download link in case you are curious about the inside of your computer.

To repair, or replace, (IN your case it would be replace), the tech has to,
1) Wear an ESD wrist s-trap, and have the alligator clip attached to a good ground source. [Electro Static Discharge]

The human body carries Static electricity. Static wil fry out the delicate hardware components inside a computer. (Laptop or desktop)
Can do it in less than the blink of an eye, and you won't see it, or feel it.

The ESD wrists-trap helps to prevent this. (It works, trust me. IF, you have the alligator clip attached to a good ground source)

A multi-compartment container is used for the various areas the screws come out of, and the various screws. There are over 60 screws, and 12 different types. Some look the same, but they Aren't.

2) The laptop must be Completely disassembled down to the bare motherboard in hand.
No Processor, Ram Memory, Wireless module, Harddrive, Optical drive, (DC/DVD drive), and other hardware components, can be attached to the motherboard.

Bare motherboard.

3) The DC Power Jack, (DC-IN), is unsoldered from the motherboard, using careful desoldering techniques.
The new jack is then soldered in using careful soldering techniques.
(Very few techs are qualified to do this anymore. They just want to replace the motherboard)

4) Then the laptop is reassembled, power sources are attached once more, and the laptop is tested.

My compaq presario will not power up (no power). I have swapped and tried a different power supply. No luck


Could be one of a few things. I'm assuming this is a presario laptop, not a desktop.

System needs to be restarted - Remove the battery and let the laptop sit a while (30 minutes). Reinstall battery and plug in power supply and see if it works. If not,

Remove the Battery and see if it is charged up (there are a set of green lights on most compaq laptop batteries with a spot to push to confirm the battery is charged). If it isn't charged, you very likely have a bad DC Jack connector on the laptop motherboard. If you apply pressure to the cord which plugs into your laptop (up and down, side to side) at the spot where the cord is connected (back of the laptop), see if the power light, on the front of the laptop, comes on for second. If it does, you can fix this by buying the DC Jack for your laptop model on ebay ($10) and removing the old connector and installing, soldering in, the new connector. This will require you to take your laptop apart. (note: Search the internet for the service manual for your laptop and this will give step by step directions on how to do this.)

Also, I think they do this at Best Buy (Nerd Herd) if you aren't comfortable doing ($75)

If it's not the DC Jack, it's a problem with the motherboard / CPU / Power Inverter or something else, most likely not worth your time to fix. You could sell the laptop for parts on ebay to recoup as much of your cost as possible, then buy another.

If you are slightly mechanical and are looking for a project and don't need the laptop immediately, you could buy the individual parts and replace piecemeal, based on directions from the service manual. FYI - I've picked up a few laptops for next to nothing and repaired this way {Compaq Evo n620c (CPU / DC Jack), IBM T22 (LCD Screen), Compaq M700 (DC Jack)}.

Laptop dead Compaq / new dc jack


Does the hard drive have to be in for the power to go on? NO

All you will get is the BIOS boot up screen then and error screen saying it can't detect hard drive.

COMPAQ V2000 WILL NOT POWER UP WITH DC/ADAPTER OR BATTERY


After you have verified that the solder is good around the DC Jack >>>>

Check MOSFET (Anachip 4407 or Fairchild 4435) near DC JACK
[replace the pair PNP/NPN]

Check MAXIM IC (MAX1999)
