Go to radio shack, and buy a *standalone* connector that is the same size as the current connector going to the back of your laptop. the good connectors will have 2 parts. the first part is what you will connect to the 2 wires after cutting off the current connecter (3 inches from the adapter to get past the short). the second part of the adapter will have 2 prongs that plug into the first piece that you splice to the power adapter cord (twisting wires). Polarity is an important factor here, so pull the battery out, then connect the power adapter. if the laptop doesn't power on with one single press of the power button, reverse the connector (pins going into opposite holes) and then try again.

Plugged in and not charging


1) Use a multimeter, check the AC adapter (Charger) for power.
Make sure it is putting out the required voltage.

Have an assistant gently wiggle the cable FROM AC adapter TO laptop. See if there is an intermittent reading on the multimeter.

Have an assistant gently wiggle the power cord.

An intermittent reading on the multimeter indicates a broken wire.
Power cord is bad? Replace cord.
Cable from AC adapter to laptop is bad? Replace AC adapter.

If you have posted the laptop manufacturer NAME and MODEL NUMBER, I could have given you more than generic information.

Model Number is in the Bottom of the laptop. Post back in a Comment.

AC adapter works OK?

Check the DC Power Jack.
The DC Power Jack is the jack on the laptop, that the AC adapter plugs into.

DC Power Jack checks OK, this is your problem,

Total Power Failure When Using the AC Adapter


1) Check the AC adapter. Use a multimeter set to DC Voltage, (Symbol is a dotted line over a solid line)

You aren't checking for voltage output, so much, as you are checking for an intermittent break.

AC adapter plugged into power, and probe leads of the multimeter touching the plug of the AC adapter going to the laptop, have an assistant gently wiggle;

1) First the power cord going to the AC adapter.
2) Then the cable from the AC adapter TO the laptop.

If you get an intermittent reading on the multimeter, you have a broken wire in the AC adapter cable, or power cord.

2) If the AC adapter shows VERY close, to the voltage it's supposed to be putting out, AND there is no intermittent break, go to the DC Power Jack.

[ A economical multimeter can be purchased for around $8 to $12.
Available in a multitude of stores. An auto parts store is but one example.

Analog, (Meter with needle), or digital is fine.

Multimeter's vary in style.
It will have a Function knob in the center. This is turned to DC Voltage.
As stated, if just a symbol, it is a dotted line over a solid line.
IF, there is more than one DC Voltage scale, set it to the 0 - 50 Volt scale.

The red probe lead is the Positive lead.
The black probe lead is the Negative probe lead.
You are testing DC Voltage. There is a Positive, and a Negative.

The plug of the AC adapter, that plugs into the DC Power Jack on the laptop, will have a Positive connection, and a Negative connection.

Plugs vary. The most common is a plug with a center hole, and a surrounding metal cylindrical shell.

The Center hole is Positive.
The outer cylindrical metal shell is Negative.

Depending on what laptop we are discussing here, the DC Power Jack can be soldered directly to the motherboard, OR it has a cable attached to it, and the cable plugs into the motherboard.
(DC Power Harness)

IF, it is the solder to the motherboard type, it has prongs, or pins, that come out of the bottom of the DC Power Jack, and goes through the motherboard. Then the prongs, or pins, are soldered to the motherboard.

With this style, if the DC Power Jack is bumped, the solder joints of those pins, may be cracked. Makes a bad contact.

Could also be bad enough to make a Short. (Laptop turns off when AC adapter is plugged in)

The DC Power Jack itself may be in bad repair.
Using as an example of the style that has a Center hole, and a surrounding cylindrical metal shell, (Inside), if the two parts touch, you can have a Short.

The diagnoses is to start with removing ALL power, AC adapter ('Natch), and Battery.
See with a small wooden object, if you can gently wiggle the DC Power Jack.

ANY perceptible movement means a bad DC Power Jack.
You will also have to partially disassemble the laptop, to check the DC Power Jack solder connections, to the motherboard.

3) DC Power Jack checks out, the problem has gone serious.

Mounted to the laptop motherboard is a power controller chipset.
It is a power MOSFET,

[ Chip and Chipset are slang terms for I.C.
Integrated Circuit,

http://en.wikipedia.org/wiki/Integrated_Circuit

The power MOSFET is a type of I.C.,

http://en.wikipedia.org/wiki/Power_MOSFET ]

If you open the laptop, and view the motherboard, this problem will be readily apparent. This chipset usually burns, and turns blackish.

Problem is when it does, the manufacturer's ID numbers are hard to read, in order to obtain a replacement ]

This is one power controller chipset that is used in a LOT of laptops,

https://docs.google.com/viewer?a=v&q=cache:oER5NNz8cwcJ:www.fairchildsemi.com/ds/FD/FDS6675BZ.pdf+Fairchild+FDS6675BZ&hl=en&pid=bl&srcid=ADGEEShOhWPjm_M-ROHme4iEMrztCTOd-28jNiy1hVLQQh_VOyv8zcXEVDB_iTQA6MuZO88UmRkDgjyW9j4CP2aIJ-4DS-h6JNM3lvxldeApQeecmz_DADCw1s7tmNLxfPknqX14SZP6&sig=AHIEtbS_rYUAeo_8rB9YHkW05ZjLqeH4Jg

This is another one,

http://html.alldatasheet.com/html-pdf/85156/VISHAY/SI4925BDY/183/1/SI4925BDY.html

Both of these chipsets uses a D2PAK surface mount.
The leads are bent into a J shape. ( J Lead)

The 'foot' of the J lead is soldered to a copper pad on the motherboard.
(Copper Pad has a thin gold plating on it)

Simple de-soldering/soldering techniques, are used to Remove the chipset.
HOWEVER, use a Heatsink on EACH J lead, when soldering the new chipset in.

(The power MOSFET has transistor/s inside )

OR, replace the motherboard.

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.

Battery is showing 100 percent but you unplug power supply computer shut down also when you wiggle cord power shuts down


The DC jack in the computer has detached itself from the motherboard causing intermittent shutdowns, the laptop must be dis-assembled to re-solder the jack back in place, and may need to replace the DC jack if the old one is not suitable.

Intermittent shutdown


Hello.

The most common reasons are the power adapter/cord and power jack.

If you move/wiggle the power adapter at the point where it connects to the laptop, and the power goes off and on, the power jack is the problem.

The power jack is inside the laptop and either needs soldering or replacement.

If no change, the power adapter is probably faulty and needs replacement.

Hope this helps.

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.

How to replace D620 power jack? pwer jack is "loose" causing intermittent connection with power supply. the problem is "not" power cord.


The power jack is located on the motherboard. It is soldered to it. You have to remove the screws behind the laptop securing the back cover and disconnect the hard drive and GPU cables remove the keyboard so that you can pull out the motherboard. This is necessary since the solder joints are located under the motherboard and the jack is over it. There are 3 pins that are soldered. Remove the solder on all 3 and pull out the jack. Insert the pins of the new jack in the space vacated by the old pins and use a low diameter solder(2mm or less if available and lead free solder only) to solder the pins to the board and voila!

Want to attach a extra subwoofer


If you have a "subwoofer-out" jack on the back of the receiver, you can put a y-cord on it and connect it to two powered subwoofers. Don't expect a big difference in the sound, however. You may even get less bass depending on where you position the sub-woofers.

Intermittent power connection


I am guessing this is a laptop.

If so, the DC jack on the laptop is bad. The connection between the jack and the motherboard gets loose, or the center pin gets loose. The only fix for this is a jack replacement. It takes soldering skills. You can get it repaired for $100-200 bucks, depending on the shop.

If you have soldering and electronic skills you can do it yourself, but it is tricky if you have never done it.

The only other option is possibly the power cord is bad at the end, where there might be a bend. Sometimes both the power cord and Jack are bad.

Acer Aspire 3610


The problem is that the power inlet jack has a bad connection on the motherboard. The way to resolve this is to remove the motherboard from the laptop and resolder the jack. This is not a repair I would suggest for the novice. If this is not repaired soon, further damage can be done to the motherboard that may not be easily fixable. Please have this repaired soon.
