    Yes it is the socket on the back where the dc adapter fits into I can put it in but I have to hold it just right for it to work. So you can not solder it? the part has to be replaced?

Yes, but its not a cheap fix depending on the laptop. The best route is either call manufacture or go to a local repair shop and see if they have parts for that type of laptop. Its really only a 10 minute job of swapping the part out. The part though has various prices so don't be surprised if someone charges you 50-60 bucks for a little piece of plastic.

    Note for solution #2 tomj23 hit the nail on the head. More in depth then my solution but same basically. As he said, make sure anyone replacing this part is trained with Laptop repair or your looking at a mess.

    Yes you might possibly be able to solder it. But it still will involve ripping the entire computer apart. Normally the tech will just replace it instead of solder it back down for the reason that replacing it with a new part will allow it to last longer then doing a quick fix.

Do you mean the socket on the laptop where the plug from the adaptor plugs into? If that is damaged it can be replaced by a repair shop and sometimes by a skilled user. The repair typically involves a fairly in depth disassembly of the laptop so the user would need to have fairly decent mechanical aptitude, a good assortment of small screwdrivers and experience handling electronics. If the laptop is still in warranty I would strongly recommend sending it to the manufacturer for repair. It may not be a warranty repair; however, if anyone else takes it apart you will void your warranty on anything else that may go wrong in the future.

    Its going to be hard to find this part. Few of the on-line sites I use carry parts for Sharp and none of them have this power socket. You might be better off talking to the local repair shop or Sharp on this one.

Power problems

Unplug the AC adapter (Charger) from power. Unplug the AC adapter from the laptop.
Remove the Battery.

Press the Power On button in, and hold it in for a count of 10 seconds.
(And I mean 10. Count, 1001,..1002,..1003,..etc)

Reinstall the Battery. Plug the AC adapter back in. Plug the AC adapter into power.

(ALWAYS plug the AC adapter into the laptop FIRST, then plug the AC adapter into power.
To avoid a voltage spike at the laptop)

WAIT 1 minute, turn the laptop on.

Still no?

Then the AC adapter needs to be checked, to see if it is putting out the correct voltage.

Don't know, Model Number wasn't stated.

AC adapter checks out, then it is on to the DC Power Jack.
The jack on the laptop (DC_IN) that the AC adapter plugs into.
What style?

Don't know the Model Number wasn't stated.

DC Power Jack checks out, then I suggest you have a problem with a Power MOSFET,

(Model Number is on the Bottom of the laptop. Plus, this IS a Dell, right?)

Post back in a Comment.


The adapter light is on when first plugged in but then when I connect the adapter to my laptop the light goes off and it doesnt supply any power

I suggest check out the AC adapter first.

1) When plugged into power, and plugged into the laptop, gently wiggle the cable from the AC adapter TO laptop.

Any change?

Do the same on the power cord TO AC adapter.

Go on.

2) The port on the laptop that the plug from the AC adapter plugs into, is the DC Power Jack.
If we are discussing an Acer Aspire 5738Z Notebook PC, the DC Power Jack resembles this one, (Not installed),

(When I note the DC Power Jack, it is this link I will be referring to )

As you can see there is a Center Pin. All power removed from the laptop, use a small wooden, or plastic object, and see if this pin moves around.

ANY perceptible movement means a bad DC Power Jack.

DC Power Jack checks out it's back to the AC adapter.
Wanted to perform the easy diagnosis first.

This will require a multimeter. An economical, yet fine for this test multimeter, can be purchased for as little as $8 to $12.

Available in a multitude of stores. An auto parts store is but one example.
Analog or digital is fine.

(Analog is fine. Some of us still like 'em)

DC Voltage is what you are going to check.

Black probe lead (Negative) goes in the Common port on the multimeter. (COM)
Red probe lead (Positive) goes in the Voltage port on the multimeter. (V)

If the multimeter just has symbols around the Function Knob, set it to the dotted line over a solid line, symbol.

The plug on the end of the AC adapter, that plugs into the laptop, has a center hole, and a cylindrical metal shield surrounding it.

The Center Hole of the plug is where the red Positive lead, of the multimeter goes.

The outside cylindrical metal shell is where the black Negative lead of the multimeter goes.

Hold the AC adapter plug in one hand, and at the same time hold the red Positive multimeter probe in the center hole.

With the other hand touch the black Negative lead of the multimeter, to the cylindrical metal shield on the outside of the plug.

You should read 19 Volts (DC), or VERY close to it,

I believe the AC adapter is the problem. Post back in a Comment as to your findings.


Hi when plug in my ac adapter into lenovo x61 the tablet will not turn on i try it on other computer and it will on what happen?

LOL, sounds like your tablet has seen it's better days. See why HP got out of the Tablet business? They are nothing but trouble.

Loose power adapter

Loose Power Adapter or loose internal dc power jack where the adapter plugs into the computer? If the Power Adapter is loose buy another one. If the internal DC Power Jack is loose, you will have to take the laptop apart to repair it. The DC Power Jack is on the motherboard and most times it is soldered to the motherboard. That means you will have to desolder the old one and solder a new one in it's place. Sometimes the dc power jack sits in a slot between the bottom case and palmrest which hold it in place and has a cable harness that plugs into the motherboard.

Gateway kav60 not charging. i have to wiggle the cord and sometimes it refuses to charge.

I guess you've got a broken laptop power dc jack or power cable.

Symptoms of a broken Laptop DC power jack:

- The laptop only operates when you hold the DC power plug in a certain direction (DC jack is broken or loose).
- The laptop only runs on battery power (no power is getting through the DC jack).
- The laptop gets no power at all.
- The laptop will not charge the battery.
- The laptop switches from AC power to battery power intermittently due to a loose or broken power jack.
- The laptop suddenly shuts off.
- The DC jack may feel loose.
- Sparks come out of the back of the laptop when you insert the power plug into the DC jack.

Dell inspirion 1501 laptop, not charging battery light showing red, have bought a new mains adaptor but still not charging

Does the back dc jack seem loose when you have the ac adapter plugged into it? Wiggle the cord right where it plugs into the laptop. If it moves around then most likely the dc jack on the inside has one of it's 3 points of contact broken. This means that someone would need to re-solder that contact or put a whole new jack into the laptop. Another thing to try is replacing the battery. Sometimes they won't charge because they are bad. Another thing to try is take the battery out, plug it into the adapter, turn it on, get into windows, shut down, put battery back in, turn on. See if that resets the battery and makes it charge.

HP home edition ze2308wm keeps seitching from AC to battery

The soldier holding the DC jack on the machine has broken loose. If you can, you should take it back to the place you had fix the jack and have them resoldier it. These are very small connection points, and if they don't get the soldier in there good, will break loose. It's a common occurrence, I've had it happen to a few of my soldier jobs, they should take care of it. Be careful with the way it is now, you can do severe damage if the connection point gaps and creates an electrical arch. I would suggest not using it until you get it fixed.

New batteries not holding charge

The problem is probably the AC adapter. If you have a voltmeter you can see what voltage is on the adapter output plug going to the base unit. Unplug the small plug from the base unit and measure. Since the batteries are 3.6 v, the power adapter plug needs to be something greater. Maybe 4.5 v. It should say on the AC adapter what it puts out (volts and max current). Usually the center is negative and the outside barrel of the plug is positive. Put the volt meter to 5v DC and put the black lead in the plug center and the red lead to the outside barrel of the small plug. If you measure a negative voltage, switch the leads. Make sure the Volt meter is not in current mode or you will be shorting the adapter at its output plug. If you get a reading larger the 4 volts then the problem is probably inside the base. There should be some circuitry to minimize charging current to the battery,.

Compaq Presario 1200 won't charge battery

dear N9YK

you can follow this

If you have a loose connection where you plug in the power on your laptop, or it works intermittently, you could have a bad dc jack. Symptoms
  • Move the power plug and the laptop loses connection
  • Broken or cracked dc jack
  • Laptop won't charge but worked on battery
  • Power LED and battery LED flicker when the adapter tip is moved
  • Battery won't charge
  • Sparks come out the back of the laptop
Why does this happen?
  • Flaw in manufacturer designs
  • Use of universal or non-original ac adapter
  • Lots of plugging and unplugging of the ac adapter
  • Tripping on or pulling the ac adapter cord
or you can check your dc amper in your adaptor




No power

Try to remove the battery and then plug the power adapter only. If does not power up try with battery only and then if not your motherboard is bad. You can send it to us and we will fix it
