I'm sure many of you have the problem of the laptop keys leaving marks on the screen when it's closed.  I just cleaned my screen using a 50/50 mix of rubbing alcohol and water.  The marks appear to be gone, but I wanted to make sure they didn't come back.  I was especially worried about this since I bought my port replicator and use it with the screen closed and a NEC monitor hooked up:

I was at WalMart today doing my weekly shopping, and I found this:

It's a foam sheet that is 9"x12" in size.  I found it in the arts and crafts section, over by where they sell fabric and stuff.  Turns out, it fits the screen perfectly:

In case you were wondering, I have an Inspiron 8200 with a 15" diagonal screen.
I also included the tag that came stapled on the pad (for reference purposes):

Now, I'm not completely sure that the pad won't harm the screen.  I don't see why it would.  It's just a really fine porous foam sheet.  Let me know if any of you guys think it'll damange the screen.  I also picked up some vinyl that I was going to use in case the foam didn't fit.  I will use that if I find out the foam is indeed harmful.  Comments are appreciated!
