If you want a repair estimate from Dell, you will need to start with a paid call to technical support: Once that's done, they will issue a repair estimate. [URL] You can also search for a screen (parts-people.com is one good source;  you can use your service tag). Ballpark estimate for a non-touch, low resolution screen:  under $100 plus labor;  for a high resolution touchscreen, probably $150-200 plus labor. You can also remove the existing panel and locate the part number on the back of the screen -- any computer shop can change a display panel.  
1) It's been a while since I've been here and I'm having a hard time finding things.  My Inspiron is out of warranty but I used to be able to at least get it's original configuration after providing the Service Tag.  When I do that now at Dell.com, support, product support it seems to only tell me I'm out of support.  That I already know!  I need to get a part number off that original configuration so I can see how much it will cost to have fixed.  Can this still be done?  If so how?   2) How can I determine if I bought this from Dell, or a retail site?   3)  In general, how much will it cost to replace the LCD?  The laptop has been sitting on a shelf inside its box for a few months.  When I got in it today the screen is cracked in several areas!  Has anyone heard of a screen cracking when the laptop wasn't even being used?   Thanks for your help.
