Why is my power adapter recognised but not charging?

Hi. I have a Dell Inspiron 1520 that's about a year old. The power adaptor is plugged in but the battery icon says I only have 7% because the adaptor is recognised but not charging. The message says "plugged in, not charging". What is wrong and how do I fix this??

    dell put a chip in their chargers that talks a protocol to the mother board via the central pin. dell purposefully exclude the use of aftermarket chargers for charging the battery. under the guise of safety its plain good old lockin

  • as mentioned above this is caused by Dell trying to stop people from using third party chargers "I have a Dell inspiron 1501, and i also had the "Plugged in, not charging" problem, the problem lies not in the laptop nor the power brick itself, bu the cord that runs from the charger to the laptop, due to the infamous "exploding battery" incidents companies started to use a 3-wire conductor, Ground, V+ and a data signal, this last one tells the laptop the electrical specs of the charger and if its a OEM one, if it is it charges, if not it disables charging the battery. so the problem is that the manufacturers makes this data signal cable hair thin and it usually breaks after some time, so the laptop doesn't get the charger info and disables the charging circuits,,,, but the charger itself is good.
    to solve my problem what i did was to open the charger, and replaced the cable with a thicker 3 or 4 wire one, but you also have to adapt the plug from the original cable.
    3rd party charger usually only have the ground and V+ conductors and no data signal one so the laptop will never charge."

    The best way to troubleshoot this is from the simplest to the most difficult solutions.

    1. Dells have a button that turns off charging. So far I've only seen it as holding down FN and hitting F2. It has a blue battery with a lightning bolt on the F2 button. Hit this once, then hover over the battery a 30 seconds later to see if it is now charging.

    2. The next problem could be the power management in Windows. Make sure you are hooked up to internet. Go to "Device Manager" by typing it in the file search box in the lower left hand corner of the screen when you hit the Windows Icon. Expand the batteries section. Uninstall all instances of "Microsoft ACPI-Compliant Control Methed Battery". Then right click on Batteries and click Scan for hardware changes. This should automatically install the correct drivers. Be sure not to uninstall any of the other battery drivers.

    3. Take your power adapter and look in the center hole. There should be a tiny pin. If this is bent or damaged, you need a new power adapter.

    4. Take your battery out and examine the pins. Look for bent or damaged pins. If they are bent or damaged, you will at the very least need to get a new shell from Dell that can have your same hard drive in it. This is unlikely as these are more sturdy, but you might as well try everything.

    5. At this point, you really need multiple power adapters and/or batteries to determine what stage of charging is failing. You will likely need to call Dell to find out who to send or take your computer to for repairs. They diagnose if it is a problem with the power adapter, battery, or internal connections within the shell.

  • Same problem with my inspiron 1525. Have replaced the battery and twice replaced the charger. Tried uninstalling the driver, but didn't work. This computer has been in the shop twice, once for a failed hard drive and its only 2ys old. So far I've spent about $400 on repairs. Maybe I should just deep 6 this piece of junk and buy another brand. Too bad, I've bought Dells for years because their quality was pretty good. This was the first laptop I've bought from them though.

    I too was a longtime Dell fanatic. Including my business I have spent over $30,000 with Dell and stuff like this has ruined my Dell experience. Dell says this is a safety measure but it is a proprietary disgrace. They did this to prevent third party chargers and it back-fired. People that have only used Dell brand chargers are also paying the price with this problem.

  • Most likely the adapter is NOT recognized. It is labeled by the laptop as "non-DELL adapter" and will provide power, but not charge your battery.

    Like romanw said last month, this is NOT a safety measure, but a way for DELL to create a proprietary monopoly on their products. If you've ever seen pictures of the DELL adapter broken apart, you'll see why this happens:
    http://www.laptop-junction.com/toast/...

    There is an un-insulated, fragile, single wire running along the outside of the brick's cable into your computer. If you bend the cable too often, that wire will snap like a paper-clip. (Try straightening out a paper clip, then bending it a little. Bend it a little more, a little more, now in the opposite direction, now back... SNAP.)

    Hopefully you don't have the same issues I have when an unknown adapter is plugged in: slower performance and keyboard errors.

    The "Dallas" ID chip in the adapter itself is unlikely to fail, so it most likely will be that thin wire. Too bad DELL will not remove that chip, nor will they create a software work-around in their BIOS.

    • This idea that the charger is not powerful enough; cited by many others, too, cannot be right. if the computer is switched off and left connected to the mains it should charge - like other similar devices; iPad, Nintendo, etc. Batteries do not require huge currents to charge, in fact they will charge with very little - trickle-charging, it's called.

  • I have a Inspiron 1420 and when I plug the power cord into the computer it says that the charger needs to be a 65W or higher and my charger is a 90W so it should charge it? I replaced the battery and got a new charger and the new one is getting no charge (green light isn't turning on when it's plugged in) I've tried every outlet in the house and no charge but other things work in the outlet. Any ideas??

  • I advice you to better get a external multi charger for charging battery while you will needed it because it is affordable option. Just try it out first if you are satisfied then go for it.

  • I believe that the frequent comments concerning the chargers being unable to cope is wrong and misleading, and should be ignored. Left plugged into the mains with computer switched off it will charge - if all other things are good - if the charger can power the computer, it can definitely charge the battery while the computer is off. No question. The computer draws much more current than is required to charge a battery alone. The problem lies elsewhere. Don't immediately rush out and buy a new charger based on this spurious claim.

  • I've seen many technically incorrect replies regarding wattage (which is a measurement of electrical power). The computer is designed to work at a certain voltage, and at that voltage (sort of electrical pressure) will pull from the power source a certain about of current (measured in amps). Just charging will draws less current than running the computer. The power supply needs to be capable of delivering the required current at the proper voltage, and that's measured in watts. It's simple math Power needed (watts) = voltage X current (amps). It never hurts to have a power supply capable of providing more power, but if it's too small, the power supply will overheat unless it contains some protective circuitry.

    All that said, I'll repeat why mine wasn't charging. I was using the wrong adapter on my Targus power supply. It came with two that physically fit, and I picked the wrong one. It would power the computer but not charge it. I have no idea, why, but when I used the correct and only slightly different looking adapter, the one with the "D" on the side, it power the computer, AND charged the battery,.

  • Dear all! I had met the same problem with my Dell Vostro 1320 - "plugged in, not charging". I supposed that this is common problem for Dell models with 3 wire adapter connection. Victor Godinez in this topic correctly explained this one year ago (you can find it above): the wire connected to central pin of the plug is braking on, nothing more. In my case the insulation of DC wire was damaged some time before close to adapter. After some time thin central wire had broken at that place. I just opened adapter, made wire shorter for couple inches, insulated this using thermo-shrinking tube and soldered it back. VoilĂ  - everything is working correctly, battery is charging!!
    I'd opened adapter using powerful knife (from all four corner, it was very easy and took 1 minute) and after repair jointed it back by fast epoxy glue (I'd used "Poxipol"). I think lots of you could make the same.
    Good luck for everyone and don't worry about this shit Dell product - a lot of other things much more important than this in our life!

    This entire problem is because people buy OEM replacement like the one you linked. That is not a real OEM Dell. It will work fine for many months but one day the laptop will refuse to charge the battery. I can't believe you would post that link. DO NOT buy generic, that is 100% not made by Dell.

  • I've been using a generic Targus ever since my Dell P/S overheated. Once I put the correct tip on the Targus (the one with the "D" on it), it worked fine, including charging the battery. My Dell P/S has worked also since that one time it got hot, but I wouldn't trust it now unattended. Also, the Targus, having a right angle plug (verses the Dell's straight plug) is much less likely to result in accidentally damaging the power jack on the motherboard by getting knocked around.

    Well everything i've read does not work! I have had 3 aftermarket chargers which have worked perfectly on the OEM battery. Now i have replaced the battery with an aftermarket 12 cell battery, it wont charge from either the aftermarket adapter or the new original dell adapter I have. Updated the BIOS and re-installed the device drivers, nothing works. THe battery came fully charged and worked fine on the computer, i ran it flat and now have to keep the AC plugged in to use it.

  • Yes, you can if you are friends with soldering iron :-), I'd written the prescription in this topic above...
    • Ok, here are a few things that I'd try:

      Try your friend's AC adaptor in your laptop, that'll rule out a broken connecter there.
      Charge your battery using his laptop, that should give you some juice to work with.
      Check the internal connecter while the adapter's plugged in, make sure power's getting to the board.
      Check for dead capacitors, the internal power gubbins could be broke..

      Hope that helps, If the problem is still exsot,I'm afraid you have to buy a new charer and hope this site can help you
