You're looking at roughly $300-$500 if you send it in to get repaired. (probably more for parts....that's just the labor for most businesses). best thing.....get a new one unless that was completely brand new. If you get a new one, and you have the habit of breaking stuff.....get the accidental coverage warranty plans from stores like Staples.
I agree with the others on the "get a new laptop" sentiment. Dell and Lenovo are always running deals left and right through their website where you can get a good laptop for $500-600.
i'd rather get a new laptop if it's not under warranty. get a monitor for home use for your screenless laptop.
you can purchase replacement screens for under 200 and do it yourself. my sister did that when she broke hers.
I think I am going to go with buying the screen off of ebay and replacing it myself. I really don't want to purchase a new laptop.
