    The computer doesn't recognize the adapter? Are you sure the adapter is good and functional? i.e. is there current coming out the computer end?

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

Hi. I bought a generic dell charger replacement for my laptop and it doesn't charge the battery, I was wondering if there was some way to make the computer properly recognize it.


Unfortunatly there is no way to make a 3rd party AC adapter function with certain dell models. The packaging ont he adapter you purchased may say that it is compatable with your computer but dell units are very specific when it comes to which AC adapters will work properly with them. The best thing you can do is return the 3rd party adapter and purchase the correct one from dell directly. The reason that dall laptops don't all work with 3rd part ACAs is becuase of a signaling line build into the laptop's motherboard. This line enables communication from the SuperIO controller on the board with a corresponding EPROM built into the AC adapter. If the SuperIO controller receives a signal from the wrong EPROM (AKA wrong AC adapter) then it will not recognize the power source and may or may not work properly or at all.

Please go to this website:
http://support.dell.com/support/topics/global.aspx/support/my_systems_info/details?c=us&cs=19&l=en&s=dhs&~tab=2&~ck=mn
And enter the service tag located on the bottom of your dell laptop. This will allow you to navigate to a page with your exact system confoguration information. Here you will be able to see the correct dell part number for the orginial AC adapter for your unit. You can then order this adapter from dell. Even though dell adapters are more expensive than generic ones, they are guaranteed to work.

Battery won't charge on dell 1505, using a Tragus adapter.


The battery charger circuit on a Dell portable will not operate using a 3rd party AC adapter. The bios automatically disables the charging circuit if an Dell Branded AC adapter is not recognized by the BIOS

I had the battery not recognized on boot up. then


the Dell AC adapter has a sensing pin so the bios can determine the wattage of the adapter. If the system cannot ID the adapter, the battery charger circuit is disabled. You'll need a functional DELL ac adapter to get the battery to charge

Replacement adapter will not charge battery


Did the old one do the same thing? If true, your battery sounds like it is dead.
