PC not recognizing AC adapter although it is working well.
Every time I turn on my Dell Inspiron n5110 laptop, I get the following message:
"The AC adapter wattage and type cannot be determined. The battery may not charge. The system will adjust the performance to match the power available. Please connect a Dell 90W AC adapter or greater for the best system performance."
I don't know why I am getting this message since:
- I am using the 90W Dell AC adapter that came with the laptop
- The adapter is charging the battery properly
- The green light on the adapter stays on all the time when in use
- The port connection is fine
-i have tried updating the bios
but in the bios main screen i have "none" in front of adapter and when i strike f1 the laptop performance reduced and i got that message many times before and it was solved by reconnecting the adapter's plug now it appears every time .
please help.

If the battery is still charging, you should be OK. Eventually it'll stop - in which case the first thing to do is replace the adapter with a new OEM Dell adapter.
If that doesn't solve the problem, replace the DC jack board:

And if that doesn't solve it, replace the mainboard.
