CAUTION: 
To guard against likelihood of electric shock, laceration by moving fan 
blades or other unexpected injuries, always unplug your computer from the 
electrical outlet before opening the cover.
 
CAUTION: 
The heat sink assembly, power supply, and other components may be 
very hot during normal operation. Be sure that they have had sufficient time to cool 
before you touch them.
 
NOTICE: 
Before touching anything inside your computer, ground yourself by 
touching an unpainted metal surface, such as the metal at the back of the computer. 
While you work, periodically touch an unpainted metal surface to dissipate any 
static electricity that could harm internal components.
