Question about Dell Inspiron™ 600M PC Notebook

1 Answer

No Power My 600M stopped charging and will not work with DC power pack. I replaced the DC Power Jack and purchased a new power supply. It still does the same thing. The green light on the power supply goes out immediately after I plug the cord into the DC jack. I welcome all the help that anyone can provide. Thanks

Acer 5610 charging difficulty

Yes! the DC jack will probably need to be resolded, and I would recommend replacing the power adapter because it may fix your problem, I find the universal supplies don't fit as tight as the original ones. is a good place to start for power supply replacement.

I have a HP dv7-1240us. My power supply went bad. I purchased a new one now my cpu doesnt charge or even power up. Need some help on how to replace the power socket. I have no idea on what else it could...

Was the new one that you purchased from HP? If so, then did the model numbers of the old one match the new one you bought? If the new one isn't an HP power supply, then that could be the reason why it won't charge your battery. Some of the "after market" power supplies will be enough to run the computer, but they aren't all able to charge the battery. It could also be the DC Jack on the motherboard that has gone bad. If you are not familiar with de-soldering a component from a motherboard, then you may want to think twice before attempting it. You will have to get the exact jack that goes to your motherboard, de-solder the old jack, & solder in the new one. Trust me, de-soldering and removing an old jack isn't always as easy as it sounds. You will have to completely disassemble your laptop to do that too, so be sure to keep track of all the little screws and which screws go where.

Plug in ac adaptor to Dell inspiron 600m and does

Sounds like you have a broken DC Power jack. This is where the small socket where you attach the AC adaptor breaks loose from the motherboard , resulting in the laptop not charging properly or at all . If you have to wiggle the power jack to get a connection then this is definately theproblem.

Most computer reapir shops can do this for about $100. Or if your handy with a soldering iron and dont mind disassembling the laptop , you can always buy a new DC jack for your make and model off ebay and try to solder it yourself!

My laptop lenovo 3000 N100 battery has a problem.. therefore i purchased a new battery but the problem with this battery is that when i use the battery it runs the laptop for 10 -15 mins and then with a...

My Dell laptop has a power problem.
The Dell Precision M20 Battery stops charging when I move the power cord on the DC adapter. When I start moving the cord left to right, the power LED light on the front goes on and off and the battery charge LED goes on and off too.
I removed the precision m20 battery and tested the laptop again. The laptop starts fine from the DC adapter when the battery is removed, but as soon as I start moving the power cord the laptop shuts off. It looks like the laptop looses power immediately.
If you have a problem like that, most likely it’s related either to the power adapter or the DC-IN power jack.
First of all, I tested the laptop power ac adapter with a multimeter. The power didn’t cut off no matter how badly I moved the cord. The power adapter output voltage was 15.45VDC all the time. That means there is nothing wrong with the power adapter and most likely there is a problem with with the power socket inside the laptop.
Now I’m going to test the power socket inside the laptop.
In order to access the power socket I had to disassemble the laptop and remove the top cover assembly with the display.
You can find disassembly instructions for many HP, Dell, IBM, Lenovo, Sony and Toshiba laptops in these service manuals and guides.
In the laptop I was fixing (Tecra M2) the power jack is attached to a DC-IN harness and this harness can be unplugged from the motherboard.
As you see, I removed the DC-IN harness from the motherboard, plugged in the power adapter and tested continuity with my multimeter as it shown on the picture.
When the power cord is still, the voltage output is 15.45VDC, the same as on the plug.
But as soon as I start wiggling the plug inside the jack, the power cuts off and voltage goes to 0. It means, the power harness is bad.
The problem was fixed after I replaced the defective DC-IN harness with a new one.
In some laptops the power socket (DC jack) is soldered to the motherboard.
If the battery stops charging when you wiggle the power plug inside the jack, either you have a bad power adapter (test it with a voltmeter) or the power jack is broken or loose.
You cannot simply unplug the jack and replace it with another one. You’ll have to unsolder the old jack and solder a new one back on the motherboard as I described in this post.
If the power jack is not broken but loose (not making good contact with the motherboard) you can resolder the old jack without replacing it with a new one.
If you want to buy a new one,you can see more information from

Dell Inspiron 1505; Battery does not charge; DC jack is loose..

The loose connection for the AC adapter means the motherboard needs to be replaced or the AC adapter jack on the motherboard needs to be replaced. (With Labor, it is about the same cost to buy a new motherboard as it is to have the old one fixed)

Motherboards are available on EBay for around $100

Wont recognise battery

Those may have 1 or 2 different problems. Cold Solder joint on Mobo. Bad DC Power Jack. 1: if it is the Cold Solder, you can reflow the solder and be done with it. 2: if it is the DC power jack, It should be replaced. For simplicity lets call them DC(A) and DC(B) There are 3 connections to it. Gnd, DC (A), and DC (B). When the powersupply is plugged in, contacts (A) touch to send +DC to the laptop. (B) is open. When the laptop is using battery power, contacts (B) touch to send power from the battery through the system. Over a period of time (inserting and removing the DC Power Cord), the contacts become fatigued, or oxidized and the DC(B) never closes - so it won't work from DC Battery. RATE ME - if it helps
