How to replace the dc socket

Generally speaking if you are not competent with a soldering iron it is best left to the professionals to sort out. However having said that, Dc sockets on most laptops are often easy to get to once you have removed the keyboard and perhaps a few other removable parts such as hard drive and possibly cpu fan. All depends on the location. I don't know without checking a service manual for this model but the dc socket normally has two cables with a possible earthing third.
The question really is why do you need to replace the socket in the first place. If it is because you have intermittent connection with the power supply, rather take laptop to shop or friend and try alternative power supply transformer as this is usually the fix.
However if the DC socket is truly messed up for another reason such as a small child sticking something in there that wont come out or such like, then the laptop will need to be dismantled accordingly.

Broke off my ac power supply nipple on the inside of my laptop where can I get a new one to solder on

Hi, if the Notebook is still under Warranty it is not recommended to remove and solder the Notebook with a Female DC Input socket of the Notebook. Although the DC input socket is available in any near by Electronic repair shop, please repair only if the Notebook Warranty is expired.

I have a hp pavilion dv7 and the power socket has come a lose i need to know which wire goes where.....

The DC Power Jack that the AC adapter (Charger) plugs into?

Look into the DC Power Jack with a magnifying glass and light you'll see it's a center pin surrounded by a barrel. Barrel has an inside and an outside.

1) Center pin. Gold and buried down in the plastic. Connected to WHITE wire at motherboard connector.

2) Inside barrel has 4 Brass fingers.
Orient the laptop so the LED is at 12 o'clock and you'll see fingers at 12, 3, 6 and 9 o'clock.

These fingers carry the + 19 volt power to computer.
The ones at 6 and 9 o'clock do, Noon and 3 are not connected.
+19 Volt power arrives at motherboard connector on RED wire.

3. Outside barrel has six brass fingers, at 2, 3, 4, 8, 9 and 10 o'clock.
2, 3, and 4 are not used,
2, 8, 9 and 10 are the power return (common, or ground) to computer.
It arrives at motherboard on BLACK wire.

4. LED is connected to YELLOW wire and controlled by computer.
Other side of LED is jumpered to a Black wire,(Ground), outside barrel 8, 9, and 10 o'clock.

Hi Mu c1020 have prover problem , it seems that


It sounds like the DC socket has either worked itself loose from the motherboard or it has broken off. Either way this problem can be repaired.

You have 2 choices available to you, you can take the laptop to reputable computer repair store and have them fit a new DC socket for you, or you can purchase a DC socket from places like eBay for example and disassemble the laptop to solder it in yourself.

In both cases the cost should be fairly inexpensive.

Please post back if you require anymore assistance.

Cpu chip fan

This sounds as if the motherboard arrived with some form of issue. It has been happening quite frequently with ASUS boards recently. The retention bracket which connects the heatsink/fan to the CPU? If so, yes, it should be connected to ensure the processor remains cool. You are correct, you will need a DVI-HDMI cable. Not to worry, though. They have become quite popular recently.

Let me know if you have any other questions.
