Before you begin
  • You need a flathead screwdriver.
  • Remove the Pocket Media Drive, if it is present.
  • Turn off the computer, and then disconnect all cables. Disconnect the Ethernet or modem cable before disconnecting the power cord.
  • Transfer the computer to a clear, flat, stable work surface over a non-carpeted floor.
  • HP strongly recommends the use of an anti-static 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.

The edges of metal panels can cut skin. Be careful not to slide skin along any interior metal edge of the computer.
  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.
