If you're in the US, try parts-people.com Chance are you either need the complete base assembly or the palmrest-keyboard assembly -- depending on exactly what's broken.  
We have two Vostro P88F laptops where the display is broken where the hinge connects. This is not the screen itself but the part that the screen, webcam, etc is mounted to. Can a replacement be purchased for this? All I find is the screens. Thanks
