This sounds like one of five things to me.
1. A faulty charger
2. A faulty Battery
3 A possible I/O daughterbord failure (if one exists in this model)
4. The motherboard could be suspect if there is no I/O daughterboard in this model.
5. Bios issues (Low level software in charge of monitoring battery levels among many other things)

Lets start with some simple things first. Will the computer run with only the charger? If yes that is great news. If No. Dont panic!

If the computer Runs well without the battery then we could very simply be looking at an issue where the battery in this laptop is "giving up the ghost" So to speak. In this scenario I would suggest getting an HP OEM battery as a replacement. Nothing used, nothing compatable. this will ensure better warranty coverage if anything is to happen.

Lets keep troubleshooting though to be sure we have exausted all aspects.

Now that we have an idea how the computer performs without the battery. Lets try to get a simple bios upgrade done on the computer to see if this resolves any of the charging issues. This is a little bit of an advanced teqnique that is as simple as running a file most times but can terminally destroy your computer if done improperly. Myself nor this website will take responsibility should you choose to go this route. You have been warned!

The first thing to do is to identify your product number. Here is a link that HP describes how this is done. You will need this to find your correct bios version.
http://h20566.www2.hp.com/portal/site/hpsc/template.PAGE/public/kb/docDisplay/?sp4ts.oid=432999&spf_p.tpst=kbDocDisplay&spf_p.prp_kbDocDisplay=wsrp-navigationalState%3DdocId%253Demr_na-c00033108-57%257CdocLocale%253D%257CcalledBy%253D&javax.portlet.begCacheTok=com.vignette.cachetoken&javax.portlet.endCacheTok=com.vignette.cachetoken

With Product number documented we now go to the hp support site to find your drivers and downloads. Please find the HP support Page Below:
http://h10025.www1.hp.com/ewfrf/wc/siteHome?cc=us&lc=en

Once there type in your product number and click the go button. This will take you to a page that offers driver downloads and such. Your new bios will be located under the drivers page.

Here is an example of what you will see but please do not use the drivers from this page as it may be the incorrect model and damage your laptop.
http://h10025.www1.hp.com/ewfrf/wc/product?product=435618&lc=en&cc=us&dlc=en&lang=en&task=

I would like to take the time to point your attention on the bottom right of the screen where HP defines: "HP expanded the battery pack recall on May 26th, 2011. Click here to validate your battery."

It looks like this model did infact have a battery recall at one point and you may be feeling the sting of not taking advantage of this while it was an option. Moving on.

Next select your Operating System from the dropdown list. Due to the age of the computer I imagine you will have Windows XP.

Once selected, you will now be able to scroll down and identify a spot to expand a tree for your bios version for your specific laptop. Download this file and be sure to remember where to save it. Simply run the .exe file that downloads and follow the onscreen instructions. Please be sure to keep your laptop plugged in and if you can make sure the battery is as charged as possible. Walk away from the laptop and come back after some time. You do not want to be the impatient one that reboots their laptop because you didnt think it was working as fast as it should. This will leave you with a very pretty paperweight.

Hopefully your computer has rebooted and my windy instructions havent lost you. Now that we have an up to date bios, is the computer acting any better? if not, we are quickly moving into a direction (if we havent already) that it would be time to take your computer into the repair shop. They will be able to identify for you if the computer has an I/O daughterboard that can be replaced. If it does not I am sure that with an up to date bios and a brand new battery that the motherboard may be failing. Due to the age of this computer, it may be time to replace it. If you have followed these instructions, I assure you, you have put in a valient effort!

Best of luck!

-Rogue

    Many thanks! Yes I was really concerned because the computer was NOT working with charger only, and the motherboard or bios issues were effectively a more concerning issue... Hopefully I could find a compatible charger and test : and, surprise surprise, everything is back to normal ! Lesson learned = a charger might deliver the nominal tension (on a voltmeter) and still be faulty ! This mean there is something more in the charger than a transformer and AC/DC bridge that can impair the charging process... So sorry to have bothered you on a Jan1st, many thanks for this extended analysis I will remind, and best wishes for 2014!!!

SOURCE: Laptop turns off when charger is plugged in !!

Charger is bad and is not putting out the correct voltage which causes the computer to shut down. Battery probably isn't much good either if it only lasts for one hour. Get new batter and charger. Ebay'ers will help you find one cheap.

SOURCE: Was using my Hp Pavilion dv7 laptop, suddenly

1. Test power adapter for output voltage. Bend the power cable in various directions while doing this to be sure that there is no broken conductors in the cable.
2. If power adapter is Ok, connect it & see if the power LED on the laptop will glow when you jiggle the power connector in various directions. If yes, then the DC jack might be loose or damaged, & need to be either re-soldered or replaced.
3. If not, then disassemble the laptop. Remove any components that attach to the laptop's motherboard first (e.g. battery, hard drive, RAM, wireless card, optical drive, ... etc.)
4. Next, remove the keyboard & the LCD screen.
5. Finally, unscrew all screws that hold the upper cover & lower cover together so that you could gain access to the motherboard.
6. Inspect the solder points connecting the DC jack to the motherboard. Make sure that none of them is loose. If any, re-solder them.
7. Inspect the center pin in the DC jack. Make sure that it is not broken or loose. If it is, then you might need to replace the DC jack.
8. When you are done, re-assemble back the laptop.

Your description totally sells you out to purchase a new Power adapter. Using your friend's very well tells you that yours is down. Some mechanics can help you repair this, but I advise you to purchase a new one (Cheaper and effective)

Try wiggling the plug around a bit to see if you can get contact. You could also try borrowing a power supply if you know someone with the same machine to isolate the problem.

Won't recognize battery charger


The battery might need to be replaced.  If it works plugged in, but is not charging....it is simply not holding the charge.  I know it seems strange that when it is plugged in without the battery it will not work, but that sometimes is the case.

Wont charge anymore? hp dv 4000


Does the computer acknowledge when you plug it in? Are there any status lights indicating AC power? If not then the electrical contacts in the laptop power plug may have broken. If you are not under warranty, you could take a peak inside the case where the connector is and possibly fix it with a soldering iron. In the meantime I'd backup any important data.
