  External Damage

  The key to recognizing external damage is to take the time to carefully inspect the computer. Here is a brief listof some steps you should take:

  With the lid closed, look carefully at the edge where the LCD and keyboard meet. Are the edges meetingevenly? Are there any cracks, dents or scratches on the exterior of the computer? Be sure to look at allsurfaces of the computer for

  cracks, dents, scratches or stains. Look over the I/O ports to see if there are any indications of damage to the ports such as damaged pins orcontacts, and cracked or chipped connectors.

  Open the lid and confirm that the hinges are working smoothly. Check for any sign of forced entry in the battery bay or around the keyboard. Carefully inspect the LCD for scratches on the display coatings or cracks in the glass. You can also

  shine abright light on the display to help identify damage. If you can boot the computer, do so and see if the display is showing white spots due to compression on theback of the screen.

  Look for a gap at the junction of the LCD bezel and the LCD panel. A gap is a sign of torque damage (thecomputer was twisted or opened too far).

  Take digital photos of any external damage found.
