I plug in my igo green charger and it lights up then goes off and won't charge. Can unplug and plug back in and it will come on then go off. I have two that are doing this. My third one works just fine. What could be the problem?

The goal is not to empty the battery and recharge like ni-cads (those have memory, these don't). These are lithiums, so we need to do the opposite...</span>
The chances are that the battery has failed. The age of the device would indicate that the battery is probably NiCd - these batteries have a memory effect that means after a while the battery thinks that "fully Discharged" would be the state that is the most usual for the charger to be used most often. You will need to open the device to get the battery out to find the part number. You will then be able to order on from an online retailer.
Coolpix Cameras are tricky to use with chargers. I will assume your USB Charger EH-69P is 100 - 240V 50/60 Hz so it CAN work in many places around the world with an adapter. Do not go over 240V or you could damage it.
These cameras like to have the power supply connected when it is on to charge - meaning if you have it connected and you plug the charger in the wall it will NOT charge. So if you plug the charger in the wall first and then plug the cable in the camera it will work. The camera is actually ON when it charges and I never REMOVE the memory card when it is ON.
When you have a dead battery. Plug the camera in and make sure the ON LED lights and the Charge LED flashes. Then don't mess with it. Let it charge completely (Charge LED stops flashing and is OFF) and then unplug it. It will turn off. Then later you can turn it on.
This is a common problem. It may be that the charger is dammaged. these Dell chargers have a micro thin communication cable in them that tell the charger to charge the battery. this micro thin cable can often break. Its use it to prevent the laptop battery from over charging, but if it breaks or becomed broken inside tha charger cable, then the laptop simply won't get the charge signal and the battery won't charge. If this is the case, then you will need to replace the charger with another Dell charger compatible with your laptop
If the laptop battery is more than 3 - 4 years old then the battery could be worn out. Rechargeable batteries have a finite number of charge and discharge cycles and will lose their charge capacity over time, i.e. won't charge to 100% and gradually the charge reduces until the battery won't charge up at all. OR The battery shows a 100% charge but when the adapter is disconnected the battery drops off to zero capacity in a very short time. If the battery drops to an unacceptable charge level then the battery needs to be replaced.
If this is a brand new item out of the box, if this were my item, I would send it back for an exchange. The charger never turns green because the battery never gets a full charge. Because of that you won't get a 7.4volt reading out of the battery, Either the battery is not taking the charge or the charger is malfunctioning and not charging proper. The lights may work for a bit while the motor won't spin because a light takes far less voltage than turning a motor. Because you don't know if it is the battery or charger and it is new I have to suggest to take it back. The sooner the better. Messing with it will just void the warranty.
If light you are talking about is on the power supply itself, you need to replace the power supply. Look on E-Bay.
If the light you are talking about is the AC power light on the laptop, then there are two things that are most likely. First is the power receptacle in the laptop. I have personally seen many of these fail. The other thing is the battery. With the system Off, and power supply disconnected, remove the battery. Wait a couple of minutes and put back in and plug in charger. If it continues to happen then it is most likely the power receptacle in the laptop.
Okay what happens sometimes is the charger gets into a feed back loop. What to do is remove the battery unplug the charger wait a few seconds (Maybe 20/30) plug the charger back into the outlet and then put the battery back in the charger. It should start to charge again and a few minutes later go to the blinking for full charge green.
It'll happen the other way as well meaning if the battery gets a memory (they say they don't but they do) you need to unplug the battery let is sit till it's cool and put it back on charge again. I've had this problem many times and have put it on charge and back off several times with in 15 minutes before it started to charge as it should.
Also these batteries do have a life span and if it's a three year old battery with many charges it could be failing meaning it just won't take a full charge.
