This computer has two possible screen models. They are similar, but one is 1280x800 in resolution and the other is 1440x900.

They are the same physical size and have the same connector, so either will work, but if you replace a 1440x900 screen with a 1280x800 screen, you will have a lower resolution than expected.

You can find your model prior to disassembly by looking up your Service Tag on the Dell support site.

Visit http://support.dell.com

Enter the Service Tag of this computer.

Go to the System configuration and then choose to look at the Original configuration of the system.

Find the line for the 14.1" screen and the resolution should be listed, allowing you to purchase the proper replacement screen.
