Dell AC Adapters use three wires.
+ voltage
- Voltage
and a third wire that tells the laptop what adapter you have plugged in. In your case either the part of the adapter has gone bad that tells the laptop what it is or the circuit in the laptop gas gone bad.

Easy test is to plug in a real Dell 65watt adapter and see if the message goes away.

Good Luck

Hi,
My name is Debbie.

After this update the BIOS of your computer.
-- Go to http://www.dell.com/support/drivers/us/en/19/DriversHome/NeedProductSelection
-- Put in your Service Tag and choose the Operating System.
-- Select the Bios and download the latest Version of Bios
-- Flash the Bios and check.

Check the Ac Adaptor status in BIOS.

Run the Hardware Diagnostics Test (PSA)
-- Restart your computer and hit F12 on the Dell Logo Screen a couple of times.
-- It Boots to the One Time Boot Menu.
-- Select the Option Diagnostics and hit Enter.
-- Check for the error.

Remove the battery and charger/ac adapter/power cord from your Dell notebook, press and hold the power button for 20 seconds to discharge any residual current inside the laptop. This clears your RAM and is like hardware reset. Replace the battery and charger/ac adapter/power cord and turn your Dell notebook on.

Boot in "safe mode". As it starts up press F8, the computer asks you if you'd like to start in safe mode. Highlight "safe mode" and press enter. See if your Dell notebook works normal.

If the problem persists, did you check if it could be your Dell notebook power cord or power source problem? Insufficient power might cause error messages that are misleading. Take the battery out and power on your notebook with the charger only. Make sure your notebook power jack and charger plug tip are securely connected. Did you notice the power jack loose?

Please reply in case you have any questions.

Thanks & Regards
Debbie_B

my bios is up to date because when i was helped to fix my wifi my bios was updated that fixed the problem why the wifi wasnt working. When I plugin my tip of plug it didn't always turn on, but i didn't worry about it because it didn't happen a lot, but I'm starting to notice it's happening a lot. When I replace plugs all i know is finding one that is compatible. So thanks for the info. I just had to make sure thank you it wasn't just my computer. I have a stepdad that can replace a voltage plug so might that work, but we don't have a 65 voltage available so I'll just order one.

It isn't 65 volts it is a 65 watt adapter.

This could be a indication that the DC-In socket in the laptop is either defective or has broken solder connections. The easy way to tell is to plug in a good Dell 65Watt adapter and see if that cures the problem. If it does then the adapter needs to be replaced. If it still has connection problems then the problem is inside the laptop.

Good Luck
Roger
