At this morning, my laptop (Dell Latitude e6410) gave me this error. I didn't do anything, I didn't change anything. And I got this docking station just 2 month ago. I made a little research on the internet but I couldn't find read solution for this situation. Now my docking station is not charging to my laptop. I'm using Windows 7.

What should I do in this situation ?

Your docking station power adapter is not recognized by your Dell notebook. As a result, your power adapter may not provide sufficient power to run the system, your battery will not charge, your system will run slowly. Please insert a 65 watt Dell approved power adapter.

Are you using the special power adapter that comes with the docking station? –  Kyle Oct 25 '11 at 12:32
    
@Kyle Yes. I didn't change anything. –  Soner Gönül Oct 25 '11 at 19:07
    
I have exactly the same problem. This morning I turned on my laptop (Latitude E6520 - bought 6 months ago) and this weird message has been appeared. I tried to uninstall the Dell ControlPoint, to upgrade my BIOS version (to A06 to A07) but still the same problem -> when I put my mouse on the little icon of the plug on Windows 7, it's write "plugged in, not charging" and the loading is blocked to 16%. I also tried to retired the battery from the laptop and boot the computer just with the battery charger plugged, and it's "working". I just need to be all the time plugged –  user107552 Nov 30 '11 at 21:08

Check and make sure the in-line power block thing didn't go bad. I've seen that happen. Or re-seat the laptop in the docking station to make sure it's not a loose connection.

Same thing happened to me. I changed the cable, but the same problem reappeared after a while

Move (up or down, left or right) the cable and it will work. The problem could be in the port of the device from inside, or the connector of the cable is faulty.

I doubt it is due to electricity because I live in Yemen, and the electricity is very weak.

This is not an uncommon problem. There are three possibilities that I have seen the most.

1) You are using the incorrect power adapter. Some Dell notebooks come with a power adapter that can charge the notebook, however they are not able to charge the notebook while in the dock. Did the dock come with its own power adapter?

2) I dont have a windows notebook handy, so Im trying to remember this properly... Go to the device manager, and under computer remove any and all ACPI power adapters and reboot. Hopefully, it will recognize the adapter and install the correct driver.

3) Lastly, some of the Dell power adapters are just bad. If they are under warranty you can call Dell and explain the problem. They may just send you a new one.
