There are different types of Dell power adapters, some of them put out different amounts of power. While it is possible that the battery is faulty, it is more likely, given your error message that the adaptor is wrong. If you got it from Dell, you can call them and they will exchange it.

Dell inspiron 1520 won't turn on.


Remove the battery from its compartment on the side of your Dell Inspiron laptop computer.


Remove the power adapter from its plug on the side of the Dell Inspiron (if your laptop is currently plugged into a wall outlet).


Press down and hold the "Power" button on the laptop for one to two minutes. This will dispel the excess electrical current that is built up inside the laptop.


Put the battery back inside the compartment of your Dell Inspiron.


Plug your power adapter back into the side of the Dell Inspiron. Press "Power." Your laptop computer will now turn on.


hope this helps

Same topic on Dell official community, may it will help.

There is high possibility that your adapter is stuffed. Dell have built in a recognition circuitry into the 65w adapters and when that goes, the system will no longer recognize it as a 65w adapter even though it is still putting out 65w. The system then shuts off the battery recharge circuit and to make matters worse it won't even charge the battery when the computer is off. It also speedsteps the processor down to half its speed so everything runs slower. Only option is to stick with a slow computer that can't be used on batteries or buy another ac adapter.

If you do not want to pay $80 for a original adapter directly from dell, there is an alternative choice to get an 3rd party charger, check this link below:

My dell inspirion ac charger will keep computer running but will not charge my battery. A pop up will inform me that the system doesnt recognize the charger.


it could be a couple things: Are you using the standard 90 Watt ac adapter, or the Travel auto/Air adapter. The travel adapter is only 65 watts can will charge the battery
If using the standard ac adapter, see if you can try another Dell D series adapter and see if you get the same error.
If same with another adapter, the issue is the charging circuit. If another adapter works, then replace the adapter.
If the charging circuit is bad, it will be the chargerboard or if intergrated, the motherboard

My battery charges but the laptop wont run on the battery


If your power adapter appears to be charging your laptop battery, but the laptop will not run on the battery or only runs for a short time this usually indicates that the battery will not hold a charge and needs to be replaced. Although it should run fine with the power adapter connected.

Not charging batteries


It sounds like you are using a 65 watt AC adapter or an Auto Air Adapter.
The system needs a 90 watt adapter to charge the battery while the system is on.

When you received the system as out of the box and you get this message "The AC power adapter wattage and type cannot be determind" let the Dell tech service know that they sent you a wrong or incorrect type of AC Adapter.
If this message not was not appearing before it just happened recently try to download and install the latest BIOS version from the support site.
If all fails remove the batt and check if laptop can work with AC adapter alone, because issues like AC not determine may not charge the battery and laptop may not work with AC as well, maybe laptop is already running on battery power.

My inspiron1521 ac adapter is not recognize


You probably need a new AC adapter. The best option is to find someone else with the same laptop adapter and try theirs. If it works then you know you need a new adapter. You can try and go to a store and purchase a generic one for you laptop if you do not have someone to swap with and take it back if it does not work. If it is still under warranty then Dell will send you a new one.
