HP laptop zv6000 won't charge battery

Laptop will not charge old or new battery, power cord and power input jack are good. Operates fine with power cord connected, turns off immediately when power cord is disconnected. Charge light comes on for a few seconds upon booting and the goes out. I am wondering if it is a broken connection on motherboard or if the internal power unit has a broken connection. Your help is appreciated

Asus UL50VT always shows charging


Either your battery or the power cord has an issue. Does the battery ever fully charge and make the charging light disappear or turn green? If not the battery could be bad.

Try running the computer off the battery by removing the power cord. if the battery starts losing charging strength real quick then your battery is bad. I've see bad batteries that say they are 100% charged but as soon as you remove the power cord it gets down to 5% i a matter of minutes.

Try running the computer on just the power cord. If it stays on and lets you operate without any problem then the power cord is good. A good power cord will not charge a bad battery.

If the laptop does not let you stay on long with the power cord, then either the power cord is bad or the DC Power Jack where the power cord plugs into the laptop is bad. If either of them is bad they will not charge a good battery.

Check your DC Power Jack which is where the power cord plugs into the computer is bad. Take an ink pen and push the tip inside the jack and see if the little pin wiggles, if so the jack is bad. You'll have to take the laptop apart to fix it. Most times it is soldered onto the motherboard, so you will have to desolder the old and solder a new one.

Is not charging battery


If the laptop works with the AC Adapter Power Cord ok without any problems except the battery is not charging, then the battery is dead. Batteries only have a useful life, then they have to be replaced.

If the laptop does not work with the AC Adapter Power Cord then either the Power Cord is bad or the DC Power Jack where the power cord plugs into the laptop is bad. If either of these is bad, a good battery will not charge.

I always get plugged in not charging when i charge my laptop even when it is not fully charged


If the laptop works fine off the power cord without any problems then your power cord is ok, but if the battery is not charging then the battery is probably dead and needs to be replaced. Batteries only have a useful life, and when it's over they have to be replaced.

If the laptop does not work with the power cord then either the power cord is bad or the DC Power Jack where the power cord plugs into the laptop. If either of them is bad the battery will not charge.

Laptop battery light won't stay on


The battery might be dead. Batteries only have a useful life and after that they have to be replaced.

Does your laptop work ok off the AC Adapter Power Cord? If so, your battery is dead and your power cord is good. If the laptop does not work off the Power Cord then either your Power Cord is bad or the DC Power Jack where the power cord plugs into the laptop is bad. In either case a good battery will not charge if the power cord or the DC Jack is bad.

Inspiron 1525: "plugged in, not charging"


Not charging means the battery is not being charged. Batteries only have a useful life of so long, then they die and will not take a charge so you have to replace them.

If the laptop works fine when the power cord is plugged in, then just replace the battery. if the laptop does not work on the power cord, then you need to either replace the power cord or look to see if the DC Jack where the power cord plugs into the laptop is broken or wiggles. When the DC Jack it bad the battery will not charge and eventually the laptop will not turn on if the power cord can't make the connection correctly.

Take an ink pen and push the tip inside the jack and see if the little pin wiggles, if so the jack is bad. You'll have to take the laptop apart to fix it. Most times it is soldered onto the motherboard, so you will have to desolder the old and solder a new one.

Sounds like your DC Power Jack where the Power Cord plugs into the computer is bad.

If the DC Power Jack is bad, then eventually the battery is going to die and you won't be able to boot your laptop. If the dc power jack is bad, the ac adapter power cord can't charge the battery.

My new laptop battery is not charging


Maybe the battery is bad. Just because it's new does not mean it will work.

Does your laptop power on and work with the AC Adapter and Power Cord? If not, that is why your battery is not charging. You need a New AC Adapter & Power Cord or the DC Jack where the Power Cord plugs into the laptop is bad or broken.

My Dell laptop has a power problem.
d600a.jpg?w=300&h=258
The Dell Precision M20 Battery stops charging when I move the power cord on the DC adapter. When I start moving the cord left to right, the power LED light on the front goes on and off and the battery charge LED goes on and off too.
dell-precision-m20.jpg?w=300&h=225
I removed the precision m20 battery and tested the laptop again. The laptop starts fine from the DC adapter when the battery is removed, but as soon as I start moving the power cord the laptop shuts off. It looks like the laptop looses power immediately.
If you have a problem like that, most likely it’s related either to the power adapter or the DC-IN power jack.
First of all, I tested the laptop power ac adapter with a multimeter. The power didn’t cut off no matter how badly I moved the cord. The power adapter output voltage was 15.45VDC all the time. That means there is nothing wrong with the power adapter and most likely there is a problem with with the power socket inside the laptop.
Now I’m going to test the power socket inside the laptop.
In order to access the power socket I had to disassemble the laptop and remove the top cover assembly with the display.
You can find disassembly instructions for many HP, Dell, IBM, Lenovo, Sony and Toshiba laptops in these service manuals and guides.
In the laptop I was fixing (Tecra M2) the power jack is attached to a DC-IN harness and this harness can be unplugged from the motherboard.
As you see, I removed the DC-IN harness from the motherboard, plugged in the power adapter and tested continuity with my multimeter as it shown on the picture.
When the power cord is still, the voltage output is 15.45VDC, the same as on the plug.
But as soon as I start wiggling the plug inside the jack, the power cuts off and voltage goes to 0. It means, the power harness is bad.
The problem was fixed after I replaced the defective DC-IN harness with a new one.
In some laptops the power socket (DC jack) is soldered to the motherboard.
If the battery stops charging when you wiggle the power plug inside the jack, either you have a bad power adapter (test it with a voltmeter) or the power jack is broken or loose.
You cannot simply unplug the jack and replace it with another one. You’ll have to unsolder the old jack and solder a new one back on the motherboard as I described in this post.
If the power jack is not broken but loose (not making good contact with the motherboard) you can resolder the old jack without replacing it with a new one.
If you want to buy a new one,you can see more information from http://www.udtek.com

Hp zv6000 batt ran down now will not charge or power up on ac power


This can be caused by a few problems, but I think yours is caused by a faulty power jack on laptop or your power adapter is no good.

Power Adapter: Plug it into the wall and notice if the light on adapter lights up or not. If it does light up, test it with a multimeter for proper voltage output. The output is labeled on the adapter sticker, an example would be "19 volts". If the adapter checks out okay then you need to look at where the adapter plugs into the laptop (power jack). If the power adapter did not check out okay, replace it.

Power jacks are known to come loose from the motherboard by the power cord being moved around from normal daily use. What happens is the jack breaks the solder joint and loses the connection. You most of the time see this problem getting worse by having to move your power cord around to get your charging light to come on.

If the computer is under warranty still, this is an issue you would turn it in for work. If it is not under warranty you are either going to need a replacement motherboard or replace/re-solder the jack (cheaper). If you are familiar with soldering circuit boards you can fix this yourself, if you are not experienced, you will have to take it into a electronics repair shop.

The jack and solder are very cheap, it is the labor that will cost you.

Hope this helps give you some direction as to where to look. Good luck.
