WARNING: There is a risk of hardware damage. Ensure the computer is shut down and disconnected from power before following this procedure. It is also recommended to use a grounding strap to discharge static electricity during this procedure. If one is not available, touch an exposed metal part of the chassis before handling the memory module.

IMPORTANT:

  • Properly installing non-Sony memory does not void the limited warranty.
  • Handle memory modules only by the edges. Do not touch the connectors or circuits.
