So, I've had my LG R405 for 1 year, 6 months now, and it's finally starting to show signs of wear and tear. I guess you could say I rely heavily on my computer for day to day school.
So, I recently found out the DC Power Connector on my laptop is getting weak. I opened up the laptop, luckily to find that the DC Connector isn't soldered directly to the Mobo, so it's easier to replace. However, I still need to find a replacement jack.
In the DC Connector, the pin inside the middle is very wobbly, and I am curious as to whether or not this may have an effect on the signal. If this is normal to be wobbly, then that solves part of my complication because I also found out that the ground solder became loose, which I plan to solder up.
So, to sum it up, does anyone know where I can buy a replacement DC Power Connector (I really don't know the size). In addition, whether or not the pin in the middle being wobbly poses as a future problem?
Thank you!

The pin inside shound be solid not move at all
yes you need new dc jack you shound be able find one google -
Thank you very much guys, and I managed to fix it up myself.
I went to a local electronics store, and I asked the guy working there to see if he could find a connector roughly the same size. He properly identified the size, and I soldered it up myself, using epoxy as well.
The end result works quite well, and I only spend $2.75 on a generic connector.
I love the modularity of the LG laptop, easy to replace power connector! -
Hey, I have the same problem with my LG R405.
I just ordered the part for it.
Can you tell me how to disassembly my laptop? Thanks. -
I'll try to simplify this as best as I can (don't have any pictures)
1) Remove screws from the bottom of the laptop:
There are lots of screws of the bottom. All the ones around the corner are visible, but there is also two of them under the battery, and one under the hard drive. NOTE: two of the screws hold the keyboard down, and you'll need to remove these two before you can proceed to taking off the keyboard.
2) Take off the keyboard
If you look at the top of the keyboard, there are 3 tabs holding hte laptop. Once you've done #1, you can proceed to #2 by using a thin sharp object like a knife and prying them out. There will be a bit of cosmetic damage, but most people don't see that.
One thing to remember when you're taking off the keyboard is that there is ribbon cable that connects the keyboard to the mainboard. You can remove the connection by pulling on the tabs on the mainboard.
3) Remove the plastic shell
First, now that you've removed the keyboard, there are 4 screws under the keyboard you need to be aware of. You need to take these 4 screws out before you can pull off the plastic.
Next, get a thin and sharp object. All around the silvery plastic cover of your LG R405, tabs are still holding it together. Gently slide your knife (or simmilar object) between the crack of the silver and black plastic on the sides of your laptop to pop it out. Once you've done this around 3 sides, excluding the side with screen attached, you can gently wiggle it out.
Note: There are some peripherals that are attached to the shell: Touchpad and Mic, so be careful. Make note of where their origianl
4) From here on, I'd say your laptop is pretty gutted. On the top left, there is a 3-pin molex connector. That is where the DC Power Connector hooks onto. To reach this spot, you will have to take off roughly 4-5 screw to unmount the laptop screen (really straight forward).
Good luck with it! -
Hi,
I'm experiencing the same problem. Could you tell me what store you bought you generic connector from? I checked future shop and the source they don't have it in store.
Kindly advise.
thanks

Does anyone know if the R405 and P300 use the same connector? I really need to replace the DC connector in my P300 but can't find any corresponding technical information about the laptops.
The P300 DC plug is 4.5mm (outer) / 1.7mm (inner hole) / 10mm (lenght), but the figures come from an OEM manufacturer so they might not be 100% accurate.
The measurements of the R405 connector with a 1.65mm pin sounds about right but I just want to be sure before I order one. -
I didn't think this thread would still be alive
I'm not quite sure my friend, but what I used was a generic connector from the a local hardware store. The guy who worked there sized it up, and it has worked fine for me. The only caveat is that the design of the generic DC Connector isn't the same shape, so I had to stick a bit of foam to ensure it is snug in place.
