New AC Power Adapter Will Not Charge a Good Battery RRS feed

  • Question

  • I recently purchased a Bestek AC Power Adapter/Charger, model # BTA07C1, for a Dell Inspiron 1525 laptop running Windows Vista.  The manufacturer claims that this adapter is compatible with the Dell Inspiron 1525.  I can run my laptop using the AC adapter but it will not recharge the battery.  I know the battery is good because I can recharge it with a different adapter.  If I turn on the computer with the Bestek adapter already plugged in and connected, I get an initial screen saying that my machine doesn't recognize the adapter's wattage and that it may not charge correctly.  Do I need to install a device driver or do something else to get the laptop to work with this adapter?  Or do I need to return the Bestek Adapter and get a different one instead?

    Note: The adapter is actually a christmas present for someone who also owns the same model laptop.  Hence the reason I have another power adapter that happens to work.
