Will not power on


When you connect the power, does the charge light lit up? this would tell you the power is transmitted to the battery, wich would mean your DC-jack (where the power goes in) is fine, and the problem might be fixed by:
  1. removing the battery,
  2. remove the power,
  3. hold powerbutton for 20 secs,
  4. re-insert power jack(not battery)
  5. press power on button.

If that didnt work, try the following to determine the DC-jack is the problem:
  1. remove battery
  2. insert power into dc-jack
  3. gently press the power plug into various directions while constantly pressing and releasing the power button.
  4. at some point the laptop should respond by turning on, meaning that you have a faulty dc-jack, which needs re-soldering or even relacement by soldering to repair.

Maybe you also notice that the power connector is very loose in the dc-jack, this might tell you that the dc-jack is the problem..

hope it helps..

How do replace the DC jack on a samsung NP300V5A laptop


DC Power Jacks for the most part are soldered onto the motherboard. There are some models where the DC Power Jack and the cable harness just sits in a slot on the motherboard. And there are some models where the DC Power Jack is soldered on a little circuit board that is secured by screws to hold it into place. In any case to get to the Internal DC Power Jack you have to disassemble the laptop. And if it's soldered onto the motherboard, you will spend time unsoldering the old broken Jack before you can install the new one. Get a quote from a local repair shop, then check the guys out at: http://www.generalsystemsconsulting.com They will repair it and ship it back to you via Fedex or UPS cheaper than most quotes you get including the shipping charge.

Broken power plugin port


The power plug in port you refer to is the DC Power Jack.

The AC adapter (Charger) converts AC electricity into DC electricity.
DC electricity has two poles. Positive, and Negative.
(Just like on a D cell flashlight battery)

The center pin of the DC Power Jack is the Positive connection.
The outer metal spring-like pieces, on the inside of the cylindrical shape surrounding the center pin, are the Negative connection.
(The pieces of spring-like metal, all connect to the Negative connection in the DC Power Jack)

Example of a replacement DC Power Jack, for the Asus Eee PC 1005HA Netbook,

http://www.batterysupport.com/asus-eee-pc-1005ha-jack-p-303527.html

[ Note*
Cannot agree with the replacement instructions they offer, at the bottom of the page.
Not everyone has access to a hot-air gun. A 25 Watt soldering iron, and Desoldering Braid, is better, and more easily accessed ]

A few articles dealing with replacement of a DC Power Jack,

http://www.laptoprepair101.com/laptop/2006/05/27/failed-laptop-power-jack-workaround/

1) Remove ALL power. Remove the AC adapter, (Charger), and Battery.
2) Observe Anti-Static Precautions. Buy, and use an ESD wrist strap.
Electro Static Discharge.

(Average cost is from $3 to $6. Connect the alligator clip to a good ground source.
I connect to an unpainted surface, of the metal frame of an open, empty desktop computer case.

I have an Acer Aspire One and when I plug the charger in I have to spin it or wiggle it or both to get the battery to charge. Once I have it in position it generally stays on charge, but if the cable is...


It could be either one Sarah.

The AC adapter's (Charger) cable, or the DC Power Jack where the AC adapter plugs into the laptop.

This is an example of the DC Power Jack not installed,

http://www.laptopjacks.com/view_part/Acer-Aspire-ONE-AOA150-ZG5-DC-Power-Jack-AC351816.html

(You can click on the three views of the jack to enlarge)

1) Check the DC Power Jack to see if it's in good repair.

Battery removed use a small flat tipped screwdriver, and Gently see if you can move the Center Pin around in the jack.
See if the Center Pin will move side to side a small amount. There is supposed to be No perceptible movement.

Referring back to the closeup photos of the DC Power Jack, the flat blade-like prongs are upside down, in relation to how the jack sits on the motherboard.

The flat prongs go down through the motherboard, and are soldered to the motherboard.
If the center pin of the jack is stationary, but the jack as a unit moves around, one or more solder joints, (Connections) for the flat prongs may be cracked.

The repair consists of completely disassembling the laptop, removing the broken DC Power Jack, and installing a new one.

Acer Aspire One service manual,

http://www.tim.id.au/blog/tims-laptop-service-manuals/#toc-acer

(Click on the blue - One - in Aspire One.
This is a PDF file. The computer you are using now has Adobe Reader on it which uses PDF files.
After you click on the file name (One) it may take up to 30 seconds before you see the first page.
It may also take additional time for the file to fully download.

(Took 12 seconds just now for full download)

No perceptible movement of the DC Power Jack? Suspect the cable of the AC adapter right near it's plug. (Plug that plugs into the DC Power Jack)

For additional questions please post in a Comment.

No light when charger connected to laptop.


You do not have to resolder the connection, the dc jack is attached to the motherboard via a cable and plug. You can purchase these on Ebay for under 20 bucks. Below is the link to the disassebly guide that will assist you.

This link here is for the DC jack...

MY GATEWAY LAPTOP NO LONGER RECEIVES POWER.


Motherboard or harddrive? I'm betting it's more towards the motherboard. The DC Power Jack to be more specific. This is the port where the AC adapter, (Charger), plug is plugged into.

The DC Power Jack is not much bigger, than the plug for the AC adapter that plugs into it. There are small pin leads that are on the bottom of this jack, and they go through the motherboard, and are soldered to the motherboard.

Accidental bumping of the AC adapter plug, while plugged into the DC Power Jack, can damage the jack. It can break the connections for the adapter plug, and/or can crack the solder joints for those small pin leads.

[Laptops use DC electricity. A flashlight battery, and a laptop battery, are examples of stored DC electricity. DC electricity has two poles. Positive and Negative. The DC Power Jack has two connections. Positive and Negative. {Even if the DC Power Jack has multiple holes in it]

There is also another known problem associated with DC Power Jacks. It may stem from a bad motherboard design.

More to the point, the area where the DC Power Jack mounts on the motherboard. In this design, the DC Power Jack motherboard area, is almost a separate part of the motherboard. It's shaped like a Peninsula. (Think of an island, with one side connected to the mainland)

This peninsula shape, has the tendency to crack away from the main body of the motherboard. Circuit traces are broken.

When the AC adapter plug is setting in a certain position, it presses the two broken halves of the circuit traces together, for a momentary contact. As the AC adapter plug is moved from this position, the circuit trace halves are moved apart, and there is no contact.

(No distribution of electricity from one circuit trace half, to the other circuit trace half. Think of a circuit trace as a very, thin, flat copper wire. When a circuit trace is broken, there is essentially a wire that is broken into two parts)

Solution?
See if the DC Power Jack can be repaired, (Solder joint connections re-soldered), or replaced.
If the DC Power Jack motherboard area is the aforementioned peninsula shape, it may require replacement of the motherboard.

There are very FEW, computer repair shops that have the technical expertise to replace a DC Power Jack. Easy fix is to simply replace the motherboard. (More $$$$$ too)

However, some laptops DO require replacement of the motherboard for this repair.
Bad motherboard design, for the DC Power Jack area on the motherboard.

Re-solder DC Power Jack solder joints? (IF, this is the problem) Average is $50 to $75 (US)
Replace DC Power Jack? Average is $125 to $150. (US)
Replace motherboard? Depends on the Gateway model. Could be $225 to $400 (US)

[Yes, most of the time the cost warrants just replacing the laptop itself, as the cost of replacing, is close to the repair cost)

Just to SHOW you ab average DC Power Jack, and the repair involved of replacing. (Doesn't show you, that the entire laptop needs to be disassembled, down to the bare motherboard in hand)

This is NOT a recommendation to replace the DC Power Jack yourself! It is just for knowledge of what is partially involved. (You can accidentally burn the motherboard when desoldering, or soldering, rendering the motherboard useless)
