Battery Not Taking a Charge

Im not sure if its the AC Adapter, the female jack inside the CPU, or the battery itself. I just learned that I should take out the battery and see what happens when I plug in the AC Adapter, ill do that later. The problem Im having is simple. WHen I plug in the ac adapter, I see the lightning icon. Then about 10 seconds later it disappears and the battery icon appears. I have to take the ac adapter out and put it back in. Sometimes the connection will last 5 seconds, sometimes a hour or so. How can I solve this problem.

It could be the ac adapter or a faulty jack as you mention, caused by a lot of use and twisting which can damage connections to the motherboard

I have an ASUS laptop which has been shutting down for the past 1 hour. It has little battery left so I have disconnected pwoer hoping it would go flat.


Asus WHAT laptop?
What is the model number? Bottom of laptop.

Two, is the laptop dirty inside?
If you have never had it cleaned, it is.

Three, "It has little battery left so I have disconnected power......."

Shouldn't have low battery power, if the thing is plugged in.

Four, have you tested the AC adapter's (Charger) output voltage?

Five, is the DC Power Jack in good condition?

[DC Power Jack (DC_IN), is the jack on the laptop that the AC adapter plugs into ]

Could be.........

A) The Battery is older than dirt........
("How old is that battery?
Lemme tell ya,.......that battery is so old that.........")

Battery needs replacing.

B) Power MOSFET's are going south for the winter, and didn't invite you, or the laptop along.

("Pssst..........let's go to the Bermuda's, but xnay on telling the laptop, or dlemaistre)

They control whether the Battery is to have a trickle charge, or full charge; OR, whether the laptop is to just run off of the AC power, and not the Battery.

(Actually the AC adapter {Charger} is a converter. Converts the AC electricity from the home, or business; into DC Voltage.
So it should be stated, ".......OR, whether the laptop is to just run off of DC power from the AC adapter)

Air is used to cool the hardware components inside the laptop.
The two hardware components that give off the most heat, is the Processor (CPU), and graphics chipset. (GPU)

When the Processor overheats it turns off. (BIOS turns it off)
This is a fail safe feature that is built-in.
Keeps the CPU (Processor) from burning up.

So the laptop could be turning off, because the Processor is turning off; due to the laptop is dirty inside.

The battery could be low on charge, because it is old; and not keeping a charge.

OR,
Power MOSFET's are bad, and battery is not being charged up.
Also no power TO motherboard of laptop, because power ends at the DC Power Jack on motherboard; and rest of motherboard isn't receiving power.

Using HP Pavilion dv6000 series, and Pavilion dv9000 series of Notebook PC's; to explain,

http://mayohardware.blogspot.com/2010/04/important-parts-on-dv6000-and-dv9000.html

So,.......
1) Is the laptop dirty inside?

2) Is the Battery more than 2 years old?

3) Does the AC adapter (Charger) prove to be good?
Putting out the required Voltage?

4) If the DC Power Jack on laptop, is the design that has a Center Pin; does the Center Pin move around, when you try to gently move it with a tool?
(BATTERY removed)

MSI S6000 power jack is very loose and does not make a connection to charge the battery or run off the electricity.


Hi,


Im very sorry to hear that, please follow these simple steps for you to be able to isolate the exact problem.


1. Removed the battery.
2. Connect the laptop directly to the power outlet without using the battery just for the meantime.
3. Turn on the laptop. If the laptop is able to power on, that means that the AC adapter is working fine as well as the DC port. If the laptop is not able to turn on, it maybe the AC adapter itself or the DC port.
4. Try to use another AC adapter if possible, make sure that that AC adapter is working fine. If the laptop is still not turning on, the problem is with the DC port itself. In that case, you will need to replaced the Motherboard itself.


Hope this will help...Thank you for using Fixya...

Check for a DC connector problem:

Symptoms of a broken power jack
1. If you wiggle the power cord or the AC Adapter connector on the back of the laptop, the power LED and battery charge LED start to flicker.
2. Battery will not charge in the laptop.
3. Laptop runs fine off a charged battery.
4. With the AC Adapter connected the laptop appears to be dead.
No power LED or battery charge LED activity.
5. Laptop randomly powers off without any warning.

If your laptop is out of warranty, then you can fix the problem by re-soldering DC-IN jack on the system board. If it

HP Compaq laptop won't charge/power from AC due to blown fuse


Hi there,

There's plenty of causes why your laptop would not power up from the AC adapter and won't charge the battery. Here are some possible causes and solutions to this problem:

Number one, if it's on battery power, the battery is dead or the battery is bad and number two the AC adapter could be bad. Let's roll out number one.

1. Take out the battery, remove main supply, hold power button down for 30 seconds. This will drain the charges in your

battery. Put only power supply in, do not put battery in, turn laptop on, put the battery in.

2. If the solution in no.1 doesn't solve the problem, pull the battery out, keep the battery out of the laptop for this test.

Take your AC adapter and check the voltage with a voltmeter. What you want to test for is voltage. Put the meter at 20

volts DC and take the tip, the power jack tip of your AC power adapter. You hold the black, (the negative part) of your

voltmeter on the outside of the power jack tip of your AC adapter and you put the red (the positive part) of your voltmeter

in the hole in the inside of the power jack tip of your AC adapter. Be very careful not to touch the red and the black part of

your multimeter and the power jack tips of your AC adapter together, otherwise it will create a short circuit.

After doing these procedures, if your AC adapter is good it will output a voltage which ranges from 18 to 19V DC on your

voltmeter, depending on the voltage that puts out on your AC power adapter. If your voltmeter doesn't show any voltage,

probably your AC power adapter is bad or damaged. But if your voltmeter shows up voltage, then we have to go to the

next possible cause why your laptop won't power on.

3. The dc jack on your laptop might be bad, if the dc jack on your laptop is bad or not making a connection to the

motherboard then it look the battery is bad as well, because the battery is now not holding a charge or even taking a

charge. Also, even if your AC power adapter is good and when you insert it to the dc jack in your laptop it could not power

up the laptop because the dc jack is not making a connection to your laptop motherboard in other words the dc jack might

got loose, that's why it's not making any connection to the motherboard. The only way to solve this is that you have to

disassemble your laptop, and take the laptop motherboard out and look where the dc jack is connected. After you found it,
take a file tool and file off a spot on the motherboard where you can reattach the power jack and use a wire to reattach

the power jack to the motherboard.

Hope you find this answer helpful. God bless.

Battery will not charge. The battery is new, verified on another laptop and it works fine (takes a charge). Unit works fine when connected directly to AC. The laptop is a Dell inspiron E1505. How do I...


This isn't easily done. Have you recently replaced your power adapter for any reason. I've found that some laptop batteries won't charge if the charger is just slightly different from the original one, even if it's another Dell power adapter. If you haven't replaced the power adapter recently then it may be that your female power jack isn't properly seated or soldered into the motherboard. To reseat or resolder the jack with require you do completely dismantle your laptop. If you're not confident it doing this, then don't try it yourself. Also, resoldering the jack isn't as easy as it would seem either. Before doing any dismantling, remover your battery, turn on your computer and gently wriggle the adapter around in the female jack of the computer. Does your computer shut off on you? If so, then you definitely have power jack issues. See madhattercomputers.com

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.

AC Power adaptor wont work without usb printer connected


Hey alberto,
First off thanks for choosing Fixya.com. The Ac adapter itself could be bad or it could be the dc jack. And also the problem with your cpu fan could also be that the fan has gone out or the motherboard itself needs to be replaced.
