It will plug in and provide power for the laptop but WILL NOT charge the battery. I'd recommend getting something different. Again, this is just a power cable, not a charging cable. But yes it will fit your Dell Inspiron 1501.

The best and safest way to determine if this AC adapter will work in your computer is to match up the output of this adapter with the output of your old adapter. The output of your adapter is listed right on your old adapter. This adapter's output is listed as DC-Output: 19.5V-3.34A-65W. Good Luck
