Question about HP Pavilion dv4000 Notebook
Power jack problem
HP Pavilion dv4000 PC Notebook which works fine except that it doesn’t get any
power from the power adapter. I know that the adapter is working fine so the
problem must be the power jack. Is it possible to find a power jack in order to
replace the dysfunctional one? The Hp service here in Greece suggested replacing the motherboard.
I believe that it is not wise to spend so much money in order to replace a fine
working motherboard with just a faulty power jack.
Is there any other solution suggested?
I am sure that power jack is a part of your mother board but you can also replace a new power jack for your mother board. I know that if you send it to HP they will charge you 398$ for repairing the notebook. I will give you a link from where you can purchase a power jack with a nominal price. You can fix it by yourself or you can go to any electronic shop for foxing this. It is as simple as soldering the new power jack on the mother board.

Hi every one i had this problem for a long time i just didnt use my lap top but i started doing research on the net and found what is called a hp quickdock it actually by passes the power supply of the laptop all together and you use the power supply that came with the laptop and have the part that plugs into the computer changed (which cost me $10.00) to work as the power supply for the hp quick dock and then you use expansion port three which is a part of the quick dock straight into your laptop the quickdock comes with an expansion port adapter which you need for the hp dv4000. when you use the quickdock the power button to turn the quick dock wont work when you use the expansion adapter but you dont need it because you just turn on the laptop with the power button and there you go i know have my laptop back amazing what a bit of research can do buy the way just a word of warning the quickdock from the hp site is approx $200.00 but do what i did did get it from ebay mine ended up costing me $52.00 including postage to australia

Ummm on DV4000 the problem is usually the power panel. The hair width traces on that board breaks when stressed.
I have had to solder wirewrap wire from the on/off button directly to the pad for the ribbon cable. Low temp tip with flux (15w iron)
Those machines show no lights when the panel if defective, so it leads you to the DC jack. But those jacks don't wear out as often.
Take a meter and measure resistance from the Power button tabs to the edges of the ribbon cable on the board. you'll find its OPEN even when pushed

Your dc-jack may be defective. There are two ways to fix it. You can resolder the dc-jack (repairs the solder connections) or replace the logic board. You can do it yourself or have a third party laptop repair service do it for you. You can try to replace the part yourself, it is available on any auction website. There is a Laptop repair guide that teaches you how to install the part yourself. Google how to resolder a dc-jack and you will find ways to repair the board, chances of success of DIY reflow are around 50%.

I was just about to buy a new HP laptop and I am not sure which, or if all current models are affected and if HP has corrected the problem since 2007.
I gather it is a problem only from constant pluging and unpluging.
My first option would be to shim the female part of the connector,
plug in the connector and secure it with some silicon cement, cut it off maybe 12 inches away and install a new connector to the charger/power supply.
This would work fine if only it is a mechanical problem.
Maybe some others can enlighten me.

Unfortunately, you're not going to like this answer: the part that isn't working is actually part of your motherboard.. which is why they're telling you the motherboard needs replacing.
Are you under HP warranty still? If your unit is under a year old, you'd be under the manufacturers' year warranty. If you had the forethought to purchase the HP Service Pack warranty, you might still have time on that.

Here's what you need when you get it fixed. . . Every laptop should come with one.
