DELL Battery Issue
Hi,
I'm using Dell Inspiron 15R 7520 Laptop. Now a day's I'm keep getting below message
"The AC power 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. Strike the F3 key (before F1 or F2 key) if you do not want to see power warning message strike the f1 key to continue, f2 to run the setup utility"
And its not charging the battery.
I thought it is an battery failure and purchased a new battery. Even for the new battery it is giving the same error
could you please help me how to fix the issue

Hello,
You might want to check out this wiki on Battery and AC Adapter issues for some information about the sources of these issues. Most of these issues can be resolved by either going into your System Setup (BIOS) and resetting the BIOS to factory settings or by updating the BIOS on your system.
To update the BIOS on your system you can go to our main Dell Support page, and input your service tag. The system will redirect you to the correct support pages for your system, where if you click on the Drivers & Downloads link you will see a list of drivers for laptop. Look for the category titled BIOS.
Some other quick things you might want to check is to see if there is physical damage on either the plug of the AC adapter or the connector on the motherboard, and the status lights of the adapter when it's plugged into the wall. Do you see the lights on the adapter tip light up when you plug it into an outlet? Have you tried a different adapter?
First, try resetting BIOS to default / factory settings and see if that helps. If not, then try updating the BIOS by downloading the latest from our support site. If neither of those help please let us know and we'll see what else we can suggest that may resolve your issue.
