Laptop Charger will only work is laptop is turned off.
I recently had to replace my original laptop charger, since my dog chewed through the cord, and I replaced it with a Targus Universal charger. Now I've had no problems with this charger until recently, and I've had it for just a few months. Whenever my laptop (Acer Aspire 3680) is turned on, the battery will not charge. However, if I put the computer to sleep or turn it off, it would charge. Additionally, I no longer have the option of putting my laptop in Hibernation mode. I don't know if this is related to the charger/battery problems or not. When the battery runs out, my laptop just shuts off, when it usually tries to save the session I'm currently in. When my laptop is on, my battery indicates that it is "plugged in, not charging."
Today a new symptom arose. When I turn my laptop off, it no longer charges correctly. The little orange light that tells me it's charging flashes on for about two seconds and then off for about 5, like clockwork. I don't know if the problem is my battery or the charger, but earlier today when I was trying to get it to charge while the laptop was on, I unplugged the charger and the little metal part that goes into my laptop was so hot it burned me. Any help would be most appreciated. Also: My laptop is a reconditioned laptop with a new battery and I've had it for less than a year. Thank you.
Re: Laptop Charger will only work is laptop is turned...
If you charger is beeping when the laptop turns on that means it is shorting. It's a swiching
powersupply and when they get overloaded the inductivities inside the
circuit can start to vibrate and emit a sound. Don't plug this charger
in anymore. It's best to get a replacement from a third party Laptop Shop.
Is the Tagus adapter your original adapter?
Check the adapter wih a multimeter to see if the voltage output is or slightly greater than what is printed on the label.
The adapter may not have sufficient amps to charge the battery and run the laptop, check the current rating of the original adapter and compare it with the Targus, it should be the same voltage and current rating or higher current rating.
If the adapter is OK then the battery is worn out and needs to be replaced. Recharageable batteries have only a limited number of charge and discharge cycles, when this is reached they just don't work any more. Buy a new battery, not a 2nd hand one because of the reasons I've mentioned.

Step 1: If your laptop charger seems broken, it's most likely because the battery will not charge. You plug in the cord, the lights come on, but the charging light doesn't change or blinks repeatedly. When you remove the power cord, the laptop shuts off instantly due to the depleted battery. There's more than one cause for this, and it's not always a broken charger.
Check the connection between the charger and the laptop. It should fit firmly in the DC jack without wiggling. If it is loose, use electrical tape to hold it in place so the charger can receive power. This is a temporary fix, however, because a faulty connection can create sparks and cause a fire or injury. A loose connection will just get worse over time, so have it sent to a DC jack specialist as soon as possible. Turn off the laptop and flip it upside down. Locate the latch that secures the battery and slide open. The battery should pop out; give it a tug if it doesn't. Apply a small amount of rubbing alcohol (Methylated Spirits)to the tip of a cotton swab and use it to clean the battery's connectors. Dirt can build up and interfere with the connection, giving the appearance of a broken charger. Let the alcohol dry completely and re-insert the battery. Slide the latch to secure it and plug in the power cord to test it. See if the laptop powers on with the charger only and battery removed. If it does, the battery is the likely culprit and should be replaced. If the charger is truly broken, the only thing to do is to replace it or the power cord attached to it. Look on the bottom and write down the part number. Call the laptop manufacturer for a replacement charger or search for the part number on eBay. If you purchase from anyone other than the original manufacturer, ask for genuine parts to reduce the possibility of problems. Troubleshoot Mag Safe adaptors http://support.apple.com/kb/ts1713
Is the new cord/charger/transformer the EXACT same power specs? When your "dog ate your charger", it may have shorted out something in the Laptop? Was it plugged it when your dog ate it?
Tell dog to grab it's allowance, and buy you a new laptop
NO?
Then protest around the dog daily until it does
(No, you have to feed it)
[Hold the dog's chew toy for ransom. Chew on it a little bit so dog will get the message. "Hey! Ain't kidding around here! Laptop or I keep this!" ]
OR,
Remove ALL power. Remove the AC adapter (Charger), and Battery. Press the Power On button, and hold it in for a count of 10 seconds. (And I mean 10. Count; 1001,..1002,..1003,...etc)
Let go of the Power On button. Do this procedure two more times. Reinstall Battery, THEN reattach AC adapter to laptop, and THEN plug AC adapter into power.
It sounds like you have a bad charger cord. Does it do the same when powered off the battery? Like it is tryin to start up. An d also make sure battery is plugged in good to the laptop,
First try starting the machine without the battery, only the charger, Then check the charger with an ohm meter to see if it's working properly. The out put readings are listed on the charger. In case of a surge, the charger is designed to go out first before damaging the system. However, this is not always the case. If the charger checks good, then you should take it in for a professional diagnostic because the problem may be with the power management system on the motherboard. One thing to keep in mind for future reference is when moving to a different location with your laptop, when unplugging the charger, always unplug the charger from the laptop before unplugging from the wall socket, and when plugging in, always plug the charger into the wall socket before plugging into the laptop. This will keep from surging your system.
