AC adapter not recognized--battery will not charge.

This question has suggested answer(s)

When checking on battery performance, my Dell Inspiron 1545 reads "64% available (plugged in, not charging)"

I just bought a brand new battery as my old one drained off in a similar way and my laptop would only work while plugged in.

Even with this new battery I am having this error. The laptop RUNS fine--but the battery will not charge. System setup reports the battery as healthy, but says that the adapter is unrecognized. I have rebooted the computer. Left the computer off a while, same thing. It absolutely will not charge the battery, not even temporarily.

Any help is very appreciated! I bought this laptop in 2008 brand new and I have heard alot of problems with Dell adapters lately. Pls help. Thanks.

  • Sounds like you have the incorrect ac adaptor. ..or....Maybe a problem with your motherboard? Have u updated your BIOS recently?

    I'd just call dell tech support or do their live chat

  • I have a studio 1747 and it is giving me the same error message "does not recognize my adapter" it has always had a dell adapter. I bought a new battery and power supply but this did nothing. Was wondsering if you ever found a solution?

  • Hello mnamos,

    Welcome to the community.

    In case the AC adapter is not able to charge the battery then the issue could be with the AC adapter or the power port on the system board. In this case I

    I’ll suggest to update the system BIOS to the latest version. Also If you have a similar Ac adapter available please try to run the system on it and check if the alternate AC adapter is able to charge the battery. If the alternate AC adapter charges the battery then the issue is with the AC adapter and replacing the AC adapter will take care of the issue. If you get the same error on the other AC adapter as well (plugged in, not charging), then you will need to replace the system board.

    Let me know of the findings, Glad to be of assistance.
