The laptop is in very good condition except that it is a cosmeticly missing one plastic screw cover in the upper left corner of the keyboard. You can see that in my photo below as I marked in red in one photo.

The original battery has been replaced with a brandy new battery. Please see the photo of the new battery. (I  show you the screen shot of my battery purchase history. I bought it from ebay too.)

Besides the OEM Win7 Home Premium, I also throw in the most common used software in PC. Also see the photo.
