HP DV4000 power problems

My HP dv4000 is 3 or 4years old, never had a problem til about a month ago, it started shutting down for no reason. now it's the ac power pin jack on the motherboard i belive. i took a pair of needle nose pliers and bent the power pin down a little bit, and now it powers up, but will only stay on for about 15 minutes, then just shuts down on it own. i've took it about half way apart tryin to get to the motherboard to check the solder joint on the ac power pin, but was too afraid to take it all the way apart. so i put it back together, and it still does the same thing. the battery will charge and say 100% but the laptop will not power up from just the battery. you have to use the ac adapter and the battery. I read the 65w power supply wasn't big enough to run this laptop and HP should of sent the 90w power supply.
HP says the 65w is plenty, and i need a new motherboard, which i know i don't need a new motherboard. My question is i found the manuals here to take it apart step by step, is this a common problem with the dv4000?
i think HP should admit this is a defect, and recall or fix the problem.
i gave over $1.200.00 for this laptop brand new, and have took really good care of it. it is just this power jack on the motherboard problem.
i don't wanna risk messing somethin else up tryin to fix this power jack on the board...but i don't think i have any other choice. i tried testing the 65w power supply with a meter, and it said it was bad, but it still works. i took the laptop to staples, and they tried another ac 90w supply and it wouldn't power up. but i can bend on the pin with needle nose til it makes contact i guess and it powers up....strange i know..Have you guys ever had to solder this jack back on the board???

    well mine dose the same but a bit more ,, I also got mine new about 3 yrs ago ,, what it dose is it runs very slow or windows dont come up or it will just shut down, I've ran clean ups, diffrent test, sometimes windows will comes up when I pick up and tilt my laptop, when it is on and runing I can hear the hard drive sounding weard, some of the test that I ran it comes down to having problums with my hard drive, also my mouse work at times and at times it dont I have to unplug and plug it again, also whaen I open programs it tends to frezz, would you think it could be the hard drive? I dont think it would be a power problum

    I have the same problem with my 4000, but with my laptop I shut it down and was unable to start it back up. I had it into a computer repair place and they told me it was the motherboard, but couldn't tell me exactly what was wrong. I don't feel fuzzy warm about their diagnosis. I think HP has a problem and doesn't want to admit it. I contacted hp about trading it in but as long as it doesn't power up they don't want it. I think $1400,00 for three years is not a very good investment!!!!!

    I am having the same problem as R05. My laptop will shut off whether on AC or on Battery power. It will do it at varying times-- occasionally right after start, so probably not heat-related. It also loads windows slowly.

Sorry to hear of your misfortune. A small problem with my Pavilion sent me searching for a solution when I encountered your post. Seems there is a class action lawsuit that may apply to your situation. Follow the enclosed link and read through the legal brief. You may find satisfaction there. You might consider calling or emailing the law firm for more exacting information. Best of fortune!

I was having the same problem. I removed the covers from underneath and cleaned it thoroughly. Problem solved.

Nope, it isn't what caused it in the first place...The ac plug was never in a position to put it in a bind, or bend it..I took good care of it...I have since took it all the way apart, and checked the ac jack on the motherboard, and it looks fine. it isn't lose, and the solder joints are fine..I also bought a brand new 120gb hard drive for it, and it didn't change anything..the ac plug is still good too.
i'd say it's a short in the motherboard, or power switch...

This is a very common our shop we have replaced hundreds of power jacks.

I would recommend you send this in for service ASAP as it could cause further damage...even to your mainboard. The jack itself is about $5.00 but the labor can vary upto about $500.00

We charge a flat rate of $129.00 in one of our shops. Make sure whoever you have fix this has experience as your laptop will have to be taken completly apart and your main board removed.

Good luck myfriend.

New Acer Aspire laptop 5560-7402 beeping and flickering

If it's new, return it A.S.A.P. for repair/replace, Unless it's been damaged or theated harshly, their is no reason for it to be giving you trouble in a month. If the AC jack is pulled, yanked, tugged...etc. it could damage the inside connections of the AC jack.

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),

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,

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.

Notebook won't power up with AC Adapter plugged in

your header for adaptor has worn out, or your AC adaptor had gone out. you can buy a UNIVERSAL adaptor which will fit any laptop from Newegg, fry's, office stores, etc. is a new adaptor does not work then you have to replace inside header. you can try taking a small knife and using it rub around inside to try to "revive" contacts. it is an expensive replacement cost

Motherboard issue

It's a power issue. The battery is flat. (No charge present) The AC adapter (Charger) is plugged in. The DC Power Jack has an intermittent contact. (The DC Power Jack is where the AC adapter plugs in. The charger)

The DC Power Jack is broken itself, or where it's soldered onto the motherboard, the solder joint/s are broken. This gives an intermittent contact. To see if this is the issue, try holding the plug for the charger over to one side, when it's plugged into the laptop. You may have to move it side to side, or up an down, to see.

If this is the issue, the DC Power jack costs about $6 bucks. The cost to replace it is $120 to $150.

The tech has to completely disassemble the laptop, until just the motherboard is in hand. The old DC Power Jack is unsoldered, and a new one is soldered in. Then the laptop is reassembled.

IF, you can find a shop! Most of the time the entire motherboard is changed out. Now you're talking Ducketts! $$$$$$$

System keeps shutting off. Power will show available, and then not available. Resoldered the power jack on the motherboard. Problem went away, and then came back.

I ran into a problem just like this a few months ago. Try installing the latest BIOS drivers from HP's website. For some reason, that fixed it for me. Also, from the BIOS or HP battery optimizer software, try running some tests on the battery to see if there is a problem with it.

Hope that helps....

HP pavilion laptop shuts down abruptly

It sounds like something is overheating to me. Also, it could be a bad motherboard. Try putting your laptop on a hard surface. I carnt stress this enough. Also, you can try cleaning out the laptops cooling vents with some compressed air (you can get it at pcworld). At the end of the day and it still wont work, send it in for repair. Good luck
