Thats a big job if you have no experience disassembling a laptop and soldering. Shops usually charge about $100 for this,although some are less.

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.

NO?
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),

http://www.batterysupport.com/acer-aspire-5738-jack-p-302046.html

(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.

http://www.youtube.com/watch?v=bF3OyQ3HwfU

(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,

http://www.cellularfactory.com/laptop/ACER/3/305268/

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

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.

I have an ASUS eee netbook. Recently the power cord hasn't been connecting well to the computer and now it doesn't even register. It's plugged in but isn't charging. Is it the cord or the laptop?



You have a bad DC connector, which came loose from the system board:


Problem symptoms:

  1. Laptop randomly shuts down without any warning.
  2. Power LED and battery charge LED start flickering when you wiggle the power cord or the AC adapter tip on the back or your laptop.
  3. The battery will not get charged.
  4. When you plug AC adapter, the laptop appears to be dead and there is no LED activity at all (DC-IN jack on the system board is broken).

Here is a tutorial on how to fix a DC connector problem. You may want to have a tech fix it.

Advent N270 netbook will not charge. Orange light comes on initially then goes off. Also when I wiggle the plug into the laptop the light flashes on and intermittently.


It sounds like either a bad connection on the motherboard or a broken wire in the adapter making intermittent connection.

1. With the power adapter disconnected, do you have a power light? This would indicate the adapter is good and the plug is questionable.

2. Check your power adapter output with a multi-meter.(be sure to wiggle the wires around) If the power fluctuates, replace the plug.

3. If the power is solid, replace the motherboard connector.

Laptop won't power on with ac adapter or battery


Could be a combination of things.

1) Battery is low. Not enough power to turn the laptop on.
Caused by;

2) AC adapter has a plug on the end of the cable. The plug plugs into a DC Power Jack on the laptop.

The DC Power Jack is bad.

2a) The DC Power Jack has a bad connection to the motherboard, (Cracked solder joints), and/or the jack itself is bad.

2b) Center Pin is loose in the jack's mount.
The back of the Center Pin where it mounts has become loose.

2c) The plastic body of the jack, which composes the jack's case, is cracked. This allows movement of the Center Pin.

2b, and 2c cause a bad connection with the AC adapter plug.

No charge to the Battery, no power to the laptop.

http://www.laptopjacks.com/view_part/For-Gateway-MX6920-DC-Power-Jack-GW51425.html

[ If this is the case the DC Power Jack needs to be resoldered to the motherboard. The cracked solder joints need to be re-melted, (Reflowed)
Entire laptop needs to be disassembled down to the bare motherboard in your hand.
(No Processor, Ram Memory, or any adapter cards mounted to the motherboard. Nada)

OR,
The DC Power jack needs to be replaced.
This entails disassembling the entire laptop, down to just the motherboard in your hand. (Same as above)

The old DC Power Jack is de-soldered, and a new one soldered in place.

Very FEW computer repair shops have the necessary skill level.
They just want to replace the entire motherboard.
IF one is available.
More Ka-Ching for them also. ]

3) The AC adapter is bad.
Not providing power to the laptop, to charge the Battery, nor give power to the laptop without the Battery.

AC adapter cord from adapter to plug, which plugs into the laptop, (DC Power Jack), may have a break in it.

May be an intermittent contact provided by wiggling the cord.
If this is the case the wires have stretched, and broken.
Wiggling causes the wires to briefly touch, and make contact.

Where this cord meets the plug itself. A lot of times there is a break in the wires in this area.

Solution is to replace the AC adapter. There are universal AC adapters you can buy, or perhaps Gateway still has some for sale.

Battery wont change


A problem is just like a mountain. You don't jump over the mountain, you climb it in steps, one step at a time.

1.How old is the battery? 1 to 2 years old, you can expect it to be at the end of it's Life Cycle. Batteries are rated in so many hours of usage.
Best bet is to let the battery charge 24 hours, then try it.

Would be nice if you someone else that has an Inspiron 1525, and they would try to charge your battery. If it doesn't charge up, you would know it's the battery. If it does charge up you can move on down the charging system, to try to find the problem.

2.AC adapter, (Charger) If you have a multimeter, set it to the 50 volt DC scale.
Laptop and desktop computers use DC current. (Direct Current) Your house, for example, uses AC current, (Alternating Current)
AC is converted to DC by the AC adapter, (Charger)

An example of DC current are flashlight batteries, and your laptop battery.
DC current has a Positive pole, and a Negative pole.
The center pin of the plug of your AC adapter is the Positive pole. Any of the four outside pins on the plug, are Negative.
The Red, (Positive), probe of the multimeter goes to the center pin. The Black, (Negative), probe goes to any of the outside four pins on that plug.
Example of a DC Power Jack, for the Dell Inspiron 1500 Series of laptops, 1525 and 1526, (This is the jack inside your laptop, where you plug the AC adapter into),
http://www.megaemarket.com/dc-power-jack-for-dell-inspiron-150150015011505.html

3.It may be that DC Power Jack itself is bad, or one of the solder connections is cracked. It's hard to see it clearly on the link I provided, (So I Right-clicked on it, Save Image As, and put it right in my My Pictures folder. Then I magnified it), but in the photo you will see some metal pins sticking out of the rectangular body.

The metal pins are sticking up. In reality those pins go down, when the jack is mounted on the motherboard. They go through the motherboard, via holes, and are soldered on the other side.
It is these solder joints that may crack, is what I'm referring to.

Solution to 1?
Obviously buy a new battery.

Solution to 2?
If your multimeter findings show lower voltage than needed, it's time to buy a new AC adapter. They have generic ones that can be used on a variety of laptops. The voltage will be stated on the top of the AC adapter.
Example: 19.2V-1.0A
That's 19.2 Volts at 1 AMP.

It may just be the plug end on the AC adapter itself. The plug end that goes into the DC Power Jack, on your Inspiron laptop.

Solution to 3?
Unless you are a skilled Electronics Technician, and have Excellent de-soldering/soldering skills, I advise taking it to a computer repair shop. It may not just be cracked solder joints. The DC Power Jack may need to be replaced. Maybe the motherboard is one of a bad design, and where the DC Power Jack attaches to it, has cracked.

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.
