frankie,

i have a c640 with s faulty powerjack
i replaced it with an other one but still no power.
(he powers up with the docking and battery though)
is it a fuse issue? if yes , wich one?

I cannot tell if the problem is related to the fuse or not, but you should search for a fuse located somewhere close to the jack. Test it with a multimeter.

paul wilmarth,

can you use drill bit to remove old jack

I wouldn’t do that. You can damage the motherboard. Use soldering gun instead.

My husband just had to repair my Dc jack on my acer 8930G the soldering was terrible, however we did not have any shrink wrap to put back on will this matter, the other problem is the length of cable they have left is so very very small it only just makes it to the connection, it was the black cable which had come adrift.

All seems to be working ok.

Thanks A Mil

How much do laptop repair stores usually charge to resolder or replace the DC power jack? I’ve never disassembled a laptop before so I plan on taking my laptop to a computer/laptop repair store.

I recently bought a Dell Inspiron 5150 whose dc jack was completely ripped from the motherboard, I mean completely desoldered. Unfortunately, he copper sleeve which surrounds the adapter sensor pin, not the positive pin in this case, came off as well. I bought a new jack through eBay and resoldered it in place. Some trace metal surrounding the sensor hole remained on the top of the motherboard, but on the bottom there is no metal to solder the sensor pin to. Are you aware of any other location on the motherboard where I can solder a wire to complete the circuitry for the the sensor pin? Thanks for your help.

(Sorry for the cross-post, mods, but I’m hoping for fast feedback!)

This site has been so helpful, as I solder and re-solder my Toshiba A60/65. Long story short, the copper “plug” had a crack, so I used the guide to “fortifying” the damaged jack, and now I have a new issue:

When I plug in the power supply to test, it (the power supply, not the laptop) beeps repeatedly (short-circuit, most likely). I’ve checked the board for stray solder, and find nothing, so, here’s my favor:

Can someone with a similar lappy test continuity between the different parts of the DC jack? Even without disassembly, take the battery out, and let me know if you get continuity between the main pin and the pins that connect to the exterior of the plug.

When testing the jack itself, off the machine, I get no continuity between any of the pins (except the 4 that hold it to the board, which is the same piece of metal). When it’s on the board, or when testing the board itself, I get continuity between ALL the points (main pin, middle pin, and 4 outer pins). I can’t imagine that is correct — any suggestions/feedback? TIA!
