Compaq Presario V2000 no power new dc jack

Any ideas on this model? Is there a power reset button somewhere on the motherboard for this? AC adapter has voltage, fan does not run, completely dead, voltage coming out of dc jack is good. Thanks...Bob

    Yes, I did more research on this model, & have come to the conclusion HP had a bad run of motherboards on this model, (burned 6 pin chip on the bottom on some), based on the complaints from others, some they will replace out of warranty, & am going to check that out. Thank-you.

    I'm on second motherboard after smoking last one (same problem with connection of power supply to motherboard). Now, it has done it again. Can I service this myself?

    no power on my computer whick warranty expired 12 months and I had it for 20 months. Thought it was the adapter, and now believe it is the motherboard.

    Replaced the dc jack, no good, turns out it is one of many bad motherboards Dell churned out that they wont own up to & replace.

    If there's no power going through the motherboard, I'd hazard a guess at it's requiring replacement.

    There's no PR button on the board itself that I'm aware of (or at least, in the time I've worked on them, I've never seen one)

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.

Power MOSFET Wikipedia the free encyclopedia

More information using a prior solution,

Dv6000 power light does not come on any more

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.

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)

(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.

No power


start wit ha power reset, remove the battery, remove the ac adapter, hold the power button for 1 minute and then repalce the battery and ac adapter, if theres no go try it with just the ac adapter, sometimes the batteries short out. if all else fails its probably the mmobo and i suggest calling compaq for warranty support

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.

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)

Compaq Presario v2000 having problems powering on


hi!

i'd say first try a known working ac adapter and if that Working AC adapter works and the system detects the battery well, then it could be the ac. If not then try to borrow a working battery to get your final conclusion. if the working battery still doesnt work properly, then it could be the system motherboard. If battery and ac adapter (working) are not available, then check the BIOS and see if it really doesnt detect the battery. try flashing the BIOS and still if that fails, then replace the battery.

hope this helps!

Regards,

Karlox
