Probable loose dc jack on hp zd8333cl laptop

Has problems charging...cord/plug (end that goes into the dc jack) has to be wiggled and adjusted it seems to get it to charge. Once I "play" with it to get that "sweet spot" it will charge. Usually, i have to leave it alone for a while to allow the charge and or use it on ac power. Its been getting harder and harder to get that right position. I had entire ac adaptor (cord and voltage adapter "brick") checked by the Geek Squad. They verified with a multimeter that the proper voltage is at the plug end that goes into the laptop. I have found a dc jack online for under 20 bucks...do I need to replace it or just fix the one that's there so its not loose anymore. if i can somehow tighten down the probable loose connection between it and the motherboard? i can't even figure out how to get the bottom cover completly off. i have taken almost a dozen little screws out...everyone that i can see/get out.

It is not a job for beginners. It requires COMPLETELY dismantling the computer and resoldering the jack to the motherboard. One slip and the computer is a paperweight. Check local PC repair shops for a price to fix it.

HP Elitebook 2530 Pindicator says battery charging but battery not charging


Could be a back power brick or DC jack yes. Power off the computer and remove the battery. With the battery out plug in just the power brick and turn on the computer. If the computer doesn't power on gently wiggle the plug into the laptop and repeatedly hit the power button if it comes on briefly then off again you dc jack is loose. If it doesn't come on at all then its the power brick. If the laptop comes on gently wiggle the plug into the PC. Powers off while wiggling DC jack.

Gateway MS2291 wont power up


Did you check the DC Jack where the Power Cord plugs into the laptop? If it is bad (wiggly or loose) then the laptop will not power on. Take an ink pen and put it where the power cord would plug into the laptop and see if the jack wiggles or is broken. If so, that's your problem.

The old power cord might be some good if the problem is with the DC Power Jack.

Bad power cord or bad connection on laptop?


Probably the DC Power Jack which is where the power cord plugs into the computer. Take a ink pen and stick the tip in where the power cord goes to see if it wiggles. If so, that's your problem.

My HP dv7 laptop wont turn on I purchased a new battery and a new cord it worked for an hour then shut off again!!!!!!!!!!


Your DC connector is loose from the system board:


Problem symptoms:

  1. Laptop randomly shuts down without any warning.
  2. Power LED and battery charge LED start flickering when you wiggle the power cord or the AC adapter tip on the back or your laptop.
  3. The battery will not get charged.
  4. When you plug AC adapter, the laptop appears to be dead and there is no LED activity at all (DC-IN jack on the system board is broken).

If your laptop is out of warranty, then you can fix the problem by resoldering DC-IN jack on the system board. If it's still under warranty, it would be fixed at no charge to you.

If your computer won't charge the battery, but the battery charges fine in another computer, and you are sure that the charger is good, then your problem is probably the DC power jack. If you wiggle the end of the power cord where it attaches to you laptop, and it starts charging properly, then the DC power jack is 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

Screen blackout when using AC cord


I think you're goin to have to replace your" dc-jack" as it's called. This is where your AC cord plugs into your laptop.DC-jack problems are very common in laptops.Over time they wiggle loose just enough to mess up the solder connection on the motherboard.Try gently wiggling your AC cord where it plugs into your computer ,if you screen returns to normal when you wiggle the plug a certain way,then you've most likely got a bad dc-jack.
