Before you begin

  • Turn off the computer and disconnect all cables.
  • Transfer the computer to a clean, flat, stable work surface over a noncarpeted floor. HP recommends that you put down a blanket, towel, or other soft cloth to protect the screen from scratches or other damage.
  • Electrostatic discharge (ESD) can damage your processor, disk drives, expansion boards and other components. HP strongly recommends the use of an antistatic wrist strap and a conductive foam pad when working on the computer.
  • Do not remove a component from its protective packaging until you are ready to install it.
CAUTION: This product contains components that can be damaged by electrostatic discharge (ESD). To reduce the chance of ESD damage, work over a noncarpeted floor, use a static dissipative work surface (such as a conductive foam pad), and wear an ESD wrist strap connected to a grounded surface.
