• Scratched (cosmetic) parts
• Distortion, deformation, or discoloration of the cosmetic parts
• Plastic parts, latches, pins, or connectors that have been cracked or broken by excessive force
• Damage caused by liquid spilled into the system
• Damage caused by the improper insertion of a PC card or the installation of an incompatible card
• Improper disc insertion or use of an optical drive
• Fuses blown by attachment of a nonsupported device
• Forgotten computer password (making the computer unusable)

disk drive might have been dropped or subject to excessive force.
