I once had the same problem, and turned out it was a faulty memory RAM.
Try a differnet RAM SODIMM, or if you got two plugged in, take one out and try again.
Alway try removing the battery then power up using AC only.
Check to see if there is a small green light on the powerpack, if not try changing the fuse.

If non of the above works, if could be a dead dc jack as you said or even worse, like fried motherboard or cpu.

Best of luck mate.

Sony vaio not charging while charger plugged in


Seemingly your laptop dc jack is dead. How to confirm it? If you should wiggle your laptop charger on a position to let your laptop charge, it indicates your dc jack is loose. Either replace it or repair it. If your dc jack works well, please check your ac adapter. Maybe your charger is dead.

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.

Acer 4620 is dead


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...

You may have a DC connector problem:

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.

Toshiba laptop battery or AC/DC adapter


step 1.First remove the battery out
step 2.Try to plug in the AC/DC adapter and see any Power light or something on your machine. If you have power light on your machine that mean your adaptor is supplying electric.But still there're some adapter that don't really supply a good DC voltage
we need to further check.
step 3: incase no light nothing on your machine you need to use analog meter or digital meter to check that your adapter is giving out DC Volatage around 16-19V
Best of luck, takecare.

Toshiba Satellite A105


The most common problem on these units is the ac connector solder joints break away from the motherboard. If you're sure the ac adapter is working, and the correct one, and it's not charging the battery (assuming the battery is good), it's most likely the problem. They don't have to appear loose to be loose.
Otherwise, it's motherboard time, or a loose screw, etc has caused a dead short on the board.
Good luck, if you have additional info, let me know.
