Replace the adapter. They are relatively cheap and your problem is solved. Just do a search on Google and you'll find plenty of them available.

Wire my ac jack for my samsung np365e5c


The AC adaptor goes into the AC socket, NOT the computer connection. The Computer connection is DC and comes from the DC side of the Adaptor. If you mean the DC socket has broken, then you need someone to replace it inside the computer.
If the AC adaptor has failed, you can buy a replacement ( 19V 3.16A 60W AC Adapter).
See the Manual

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,

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

How do i change out the charger port of my gateway p-6301? I believe this is the issue... I have tried replacing the battery and power cord, but it still will not detect that the cord is plugged in.


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...

Dell latitude e6410 chargin fault ,will run on dc adapter but shows not chargin ,battery not conected


  1. If the motherboard has ever been replaced, check the service tag section of the BIOS. If it is blank, enter the service tag off the bottom of the system. (The charging circuit will not work without it.)
  2. Also in the BIOS see if the AC adapter is identified or is listed as UNKNOWN. If the system cannot ID the adapter as a Dell Branded AC adapter 90w or larger, then the charger is again disabled. If unknown, check the barrel end of the DC jack of the adapter for the fine wire in the center, if broken or bent, then the adapter is not identified.
  3. Try with a different Dell branded 90w or larger D or E series adapter.
if all the above make no difference, and the Adapter is recognized, the battery may be at fault.
http://www.fixya.com/support/r3743571-long_will_battery_in_portable_computer
if the adapter is unknown, replace the adapter, unless it works normally on another system, and the other system's adapter has the same issue, in that case the motherboard is likely the issue.
Note: a 65w Auto/Air adapter will only charge the battery if the system is OFF

Kensington 33403 power adapter beeping and providing no power


I have the same model. I pinched the cord from the from the supply to the notebook. The cord looked ok from the outside, but was damaged internally. I called Kensington support and they sent out a referb unit at no cost using only the serial number to validate the date of manufacture. The company has a two year replacement policy from purchase date, but if you lose your receipt they came go by maufacture date. give them a call.
