Installing system memory modules
CAUTION:
You must disconnect the power cord and wait approximately 30 seconds for the power to drain
before adding or removing memory modules. Regardless of the power-on state, voltage is always supplied to
the memory modules as long as the computer is plugged into an active AC outlet. Adding or removing
memory modules while voltage is present may cause irreparable damage to the memory modules or system
board.
The memory module slots have gold-plated metal contacts. When upgrading the memory, it is important to
use memory modules with gold-plated metal contacts to prevent corrosion and/or oxidation resulting from
having incompatible metals in contact with each other.
Static electricity can damage the electronic components of the computer or optional cards. Before beginning
these procedures, ensure that you are discharged of static electricity by briefly touching a grounded metal
object. For more information, see
Electrostatic discharge on page 25
.
When handling a memory module, be careful not to touch any of the contacts. Doing so may damage the
module.
