I am using the original power adapter with the Dell Inspiron 6400 laptop and now when it boots up I get the following error message.
The AC power adapter type cannot be determined. You system will operate slower and the battery will not charge.
Please connect a Dell 65 W AC adapter or higher for best system operation. To resolve this issue, try to reseat the power adapter."
I don't have another power supply or laptop to try.
Is there a way to test the power supply, or whatever the computer uses to determine the power supply size?
