The pin that u put the charger in has went back in the laptop. how to open it to get to it to fix it.

The power socket on a laptop is usually soldered directly to the mainboard. Sometimes the socket is on a seperate smaller daughterboard or on a cable that connects to the mainboard, but usually this is not the case. Opening the laptop to perform this repair can be very trick and time consuming. I would certainly not recommend an amateur attempting this repair as usually the entire board needs to be removed, the socket de-soldered and a new socket soldered in place. Not for the faint hearted! If you wish to provide laptop model details I may be able to provide the screw locations etc and disassembly guide.

Socket of my laptop has broken where we connect our power supply..still we can charge it if we connect through some angles....if we need 2 change the whole board..or can replace the socket much...

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.

How do you replace the power jack socket?

Hi there,

I'm a laptop repair specialist. The DC Power Jack is soldered to the motherboard. While I am able to do this repair I no longer take the trouble because there are many vendors on eBay who perform the service for half, or less than half, of what I'd have to charge a customer.

Go to eBay and in the search window type in "Laptop DC Power Jack Repair". You will be re-directed to a page with many choices of vendors where you simply send them the laptop and they return it repaired. You should expect to pay between about $85 to $125 including all shipping.

Take care,

How to fix HP Pavilion DV6405US internal power connector broke won t charge

It pays to determine if the fault is the laptop's power socket first.
Please read the following and carry out the tests to determine the fault.

If the laptop battery is more than 3 - 4 years old then the battery could be worn out. Rechargeable batteries have a finite number of charge and discharge cycles and will lose their charge capacity over time, until they won't charge up at all.
Check power adapter’s DC plug that connects into the laptop power socket with a multi-meter, the voltage should be slightly higher than the voltage that is printed on the label on the bottom of the adapter. If the voltage is zero or way below the voltage that is printed on the label then the power adapter is faulty and needs to be replaced.
If the adapter is OK then connect it to the laptop and power it up, then look at the power/battery charging LED light and wriggle the power plug in the laptop's power socket. If the power/battery LED light flashes and in a certain position this LED light stays firm, then the power socket is either faulty or it has a dry solder joint where it is connected to the motherboard.
This can be repaired but it requires the laptop to be completely dismantled to get at this power socket and repair. If you cannot DIY then I suggest you get a quote first.

Dry joint problem on power socket


First thing is to remove the top bezel. This is the piece of plastic between the keyboard and the display. Since you have removed all the bottom screws, you should be able to pop the bezel off by inserting the tip of a small flathead screwdriver under one of the plastic hinge covers. Check the back of the hinge covers for screws and remove any you see first. Once the bezel is off, remove the screws securing the keyboard and remove the keyboard. Be careful with the keyboard ribbon cable and the connector for it, they are fragile. Flip it over and remove any bottom panels. Disconnect the wireless antenna cables from the wireless card (usually black and white). Flip it over again. Snake the wireless antenna cables up through to the top and disconnect the other thicker cable (video and power) from the mainboard. Now you need to remove the display. After the display is off, remove the optical (dvd) drive. Remove any case screws you see from under where the keyboard was. You should be able to get it apart now. Be VERY mindful of connector wires/ribbons as you take it apart.

When soldering the joints (do em all on the power jack) be careful not to heat up the area too much as there are often very sensitive fuses close to the power jack. Do the joints quickly and do not use an excessive amount of solder. After you solder it, dry-fit the laptop back together and test it. If it's good, lay a small bead of hot glue around the base of the dc power jack to reinforce it.

I have hp pavilion ze4500.Its Power plu in socket is malfunctioning.Power gets disrupted frequently & gets on after shaking the pin in the socket.How to open & replace the socket.

You have to be good with soldering to replace it.
you have to order the Jack from a place like eBay (or a place where you can get them).
you will have to remove the keyboard ,hard drive ,memories ,CD drive ,monitor and casing that holds board in place a lengthy process.
here is the service manual :

The only other option is to replace the motherboard itself and this can be costly.

I would like to try to get to the power supply socket, check it, and locate a replacement part,, can you tell which screws on the bottom will let me split the case to get to and test the socket thanks bill

Those sockets are soldered directly on the motherboard in most cases, you are going to have to take the computer totally apart and put it back together successfully. Its not as easy as it sounds. If you can solder and desolder then you can order the laptop ******** ebay by searching for your model number + "DC jack". Desolder the old one, resolder the new one then try and put it back together. Most of the screws on the bottom will have to be removed to take out the motherboard.

How to remove the back off my smasung x05 laptop

You are looking at a real job here. The socket is soldered to the motherboard. You will have to completely disassemble the laptop and de-solder the DC socket and re-solder it. Not a job for the faint of heart, not to mention someone without real soldering skill.
I can't tell you the actual steps, but you'll have to unscrew the screws in the bottom of the case, remove the bezel that covers the display hinges, remove the keyboard, display, the palm rest, and then remove the motherboard.
FYI, the palm rest is held to the base by little plastic catches--so you have to be really careful when using a screwdriver to separate the two plastic pieces.

It's probably the power socket on the laptop not the power jack on the AC adapter. You need to open the laptop by removing the casing screws. Then remove the motherboard from the base so a new socket can be soldered on.
