While not required, providing your laptop's model and serial number will help us immeasurably. We can find technical manuals that help us determine the amount of labor needed to assemble/disassemble the laptop, and we have a much easier time finding and verifying we've got the correct part for your laptop. That being said, where is it?

It's almost always on the bottom of the laptop. Dell calls it a Service Tag, most companies label it S/N. If you don't see it on the bottom, try removing the battery, newer laptops may have the sticker there. If you don't feel like turning your laptop over, you can do the following:
