This is usually quite a tricky repair on laptops as you'll need to solder the new jack socket to the motherboard in the laptop.

If you cant get the original socket, you could get a chassis mounted socket, mount the socket onto the case where the old jack was and fix it in place with a nut. Then solder 2 pieces of wire from the socket to the motherboard.

Watch the polarity though, else you'll have a fried motherboard!!!

Suggestions;

Anti-Static wrist strap connected to ground source, and your wrist;

1) The jack your AC adapter plugs into on the motherboard, is the DC Power Jack.
Motherboard out of case, power to motherboard, take your multimeter and see if you are getting 19 VDC at the DC Power Jack's positive solder joint, on motherboard.

The center pin of the jack is Positive. (The inner cylindrical shell is Negative)
Follow the DC Power Jack's positive pin from the Center of the jack, to the motherboard.

You probably won't be able to touch your meter's Positive (Red) probe, to the DC Power Jack's positive pin under the jack; so touch it's solder joint on the opposite side of the motherboard.
(DC Power Jack should be soldered close to the motherboard, is why)

Of course also touch the Negative lead, (Black probe), of your meter, to the Negative, (Ground) solder joint for the DC Power Jack.

Getting 19 volts DC?

See if there is a cracked solder joint, for any of the DC Power Jack's pin connections to the motherboard.
ANY perceptible movement of the DC Power Jack on the motherboard, indicates a bad power jack, and may indicate a broken/cracked solder joint.
Center pin of DC Power Jack is loose? Bad DC Power Jack. Replace.

2) DC Power Jack is determined to be in good repair? No cracked/broken solder joints?
The next components in the power circuit on the motherboard, leading From the power jack, are P. MOSFET's.
Power MOSFET.

3) The last thing that concerns me, although I probably should have listed it first; is the AC adapter you are using.
Concern is that it doesn't have the 'intelligent chipset' that matches the Compaq CQ1-1225 All-In-One desktop PC's circuitry.

Wait a minute. What?

From what I read;
1) One wire of the AC adapter (Charger) is hot to the touch.
'.....when I touch the charge one part of the wire is very hot."

2) AC adapter checks out as far as voltage is concerned.
"I tested the charger voltage and everything is ok."

3) "Sometimes when I touch the charge appear the icon...Could it be the charger broken wire?"

Does this mean, "Sometimes when I touch the AC adapter (Charger), the battery icon appears."?

Battery is CHARGING icon?

Could it be a broken wire in the power cable TO charger?

Uh, yeah.

1) AC adapter NOT plugged into the DC Power Jack, plug the power cable of the AC adapter into power.

Multimeter set to DC Voltage, and proper scale, red Positive lead to harness wire that goes to DC Power Jack's center pin;

,black Negative lead of multimeter, to wire that goes to DC Power jack's inside cylindrical metal shell;

Now gently wiggle the cable from the AC adapter, TO the DC Power Jack of the laptop.

Do you get an intermittent reading?

2) Also, how did you replace the DC Power Jack? What steps did you take?

http://www.dcpowerjacks.net/catalog/index.php?main_page=product_info&products_id=1291

Did you reuse the wire harness, and solder it to the DC Power Jack?
Have a lot of experience in desoldering/soldering?
What tools did you use?

25 Watt soldering iron?
.025 or .030 rosin core solder?

Desoldering Tool, or Desoldering Braid? (Solder Wick)
Side Cutters instead, and slightly shortened the wires of the DC Power Jack's harness?
(Then tinned the wires, and soldered the wires of the DC Power Jack harness, to DC Power Jack?)

Damp sponge, and cleaned the well tinned No.2 chisel tip, of the soldering iron, frequently? Used rosin solder flux?

Center pin wire (Positive), of harness cable TO DC Power Jack, was soldered to the center pin of the DC Power Jack?

Negative wire of cable TO DC Power Jack, was soldered to the inside shell of the DC Power Jack?
(Cylindrical shell, inside the DC Power Jack, that surrounds the center pin of the jack)

Sure there are no cold solder joints?

Not trying to 'browbeat' you, just am curious.

1) IF you are SURE you have the polarity correct, of the wires in the harness cable, that goes to the DC Power Jack;

,and you are SURE there is no broken wire, in the cable from the AC adapter (Charger) TO the DC Power Jack;

,and you are sure you made good solder joints;

I suspect the power correcting chipset on the motherboard, to be bad, or perhaps a Diode.

One example of the chipset I am referring to. This one is used in a lot of laptops. May not be used in yours, but gives you something to refer to when looking for a bad chipset, in the power stage, on your motherboard,

https://docs.google.com/viewer?a=v&q=cache:oER5NNz8cwcJ:www.fairchildsemi.com/ds/FD/FDS6675BZ.pdf+Fairchild+FDS6675BZ&hl=en&pid=bl&srcid=ADGEEShOhWPjm_M-ROHme4iEMrztCTOd-28jNiy1hVLQQh_VOyv8zcXEVDB_iTQA6MuZO88UmRkDgjyW9j4CP2aIJ-4DS-h6JNM3lvxldeApQeecmz_DADCw1s7tmNLxfPknqX14SZP6&sig=AHIEtbS_rYUAeo_8rB9YHkW05ZjLqeH4Jg

Usually when bad the top of the chipset will be blackened, or bubbled.
A Diode is a one way valve for electricity. When they go bad it is visually obvious.

My Q430's power connection is loose and not changing battery. Do I have to swap out motherboard?


The DC Power Jack is the jack you plug the AC adapter (Charger) into. (DC_IN)
The DC Power Jack for the Samsung Q430 series of Notebook PC's, consists of a;
1) DC Power Jack, which is connected to two wires.
2) The wires end in a small male plug connector.
It is now a DC Power Harness,
http://www.laptopjacks.com/part/Samsung-Q430-DC-Power-Jack-J-SM371300C1.html
FOLLOWING Anti-Static Procedures, the laptop is disassembled far enough to unplug the DC Power Harness, and plug a new one in.

Dc jack of labtop getting vey hot


A common weak spot on most laptops is the DC power jack. If someone trips on the wire while you have the power adaptor plugged into your laptop, chances are that the power jack will get damaged.
On most laptops the DC power jack is soldered directly to the motherboard and there are only three or four small pins holding it in place. Unfortunately that makes the power jack quite weak. Any sideways pulling of the DC power cord while attached to the laptop will usually dislodge at least one of these pins, breaking the solder around it. Modern laptops use quite a lot of power, from about 70W to 120W or even more. The bad electrical connection from the dislodged pin will cause sparks and heating that will eventually burn a hole through the motherboard and can even be a fire hazard.

The usual signs of that are:
  • The battery is not charging properly or stays at half charge despite that you have been using the power adaptor.
  • The screen flickers (the brightness is changing) while the power cord is plugged in. This is caused by the laptop switching between DC power (screen is brighter) and battery power (screen is dimmer).
  • The DC plug gets hot after a few minutes of use and may even smell of burning.
  • There are "scratching" sounds coming from the DC jack.
You need to take the unit apart and check/resolder the DC jack on the system board.

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it and give a testimonial for my response

Thanks, Joe

Hello my laptop t41 power is not even flash but the adapter is working,am technician and i have troubleshoot allot.


I concur with what Diegotech stated.

To iterate further;

1) The DC Power Jack (DC IN), may have cracked solder joint/s on the motherboard connector, (Female), where the DC Power Jack plugs in.

Resolder

2) The DC Power Jack may be broken.
Center Pin mount, and/or body of DC Power Jack, and/or Outer Shell mount.

Replace DC Power Jack.

3) Wires from the DC Power jack plug to the female connector on the motherboard, may be bad.

Replace DC Power Jack.

2) http://www.machinaelectronics.com/store/buypart/IBM_Thinkpad_T41/DC-P001

Past this point it's a bad DC sensor on the motherboard.

Replace motherboard.

Can the dc power plug be repaired?


If you are referring to the DC Jack..(the port where your AC Adapter Plugs into) then typically No, THey are cheap enough that it is best to replace with new.... Yes they can be repaired, but chances are they won't hold up to the stress, and will just cause problems down the road...

Desolder The Faulty DC Jack... Go Slow, Use Solder Wick/Desoldering Braid... And A Solder Gun...Flip Motherboard to the underside of the DC Jack, You want to put a very small amount of FRESH solder on all Pin ends of the DC Jack - this will allow better flow of the solder when trying to remove...
Then Use The Desoldering Braid and slowly remove the solder from the DC Jack Pin Contact Areas... Do Not Rush or you will ruin the contact pads on the motherboard, you must make sure all solder is removed,,, if you attempt to rip out the jack cause you think its "good enough" you will end up pulling the C ring from the center of the Jack Pin Hole...

Once You Have All Solder Removed Use Some Flux Paste And Again go over each pin to ensure all solder is gone, then you can remove the faulty DC Jack...

Now.. Clean the motherboard where the DC Jack Was... Remove All Old Flux and take your solder gun and go over the Jacks contact pads so that you have fresh solder on all...

Now Add a small amount of flux to all the DC Jack Contact Pads and add alittle to the Pins on the replacement DC Jack.....

Then Solder The New DC Jack Into Place... Solder The BottomSide First... The Pin Ends ..

Then Flip Over and add small amount to the side negative pins and the power pin(s)...

Now you are done..

You can add Some Heat Resistant Automotive Epoxy ( Safe On Electronics) to the sides and back of the new dc jack.... this will double the strength and prevent future damage/wear and tear...

Dell inspiron 9300 doesn't charges i doubt its dc jack is broken , wanna fix it


If it works from DC jack try to change the battery first, for example to the same battery from another comp. If DC jack is broken and laptop don't works from wall outlet better change the jack in service center. Disassembling Dell is hard work... Cheers.
