Installing DIMMs

CAUTION:
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. If you see an LED light on the system board, voltage is still present.
The memory module sockets 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, refer to Appendix D,
on page 47.
When handling a memory module, be careful not to touch any of the contacts. Doing so may damage
the module.
1. Remove/disengage any security devices that prohibit opening the computer.
2. Remove all removable media, such as compact discs, from the computer.
3. Turn off the computer properly through the operating system, then turn off any external devices.
