Installing SODIMMs
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 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 the following procedures, be sure that you are discharged of static electricity by briefly
touching a grounded metal object.
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 USB flash drives, from the computer.
3. Turn off the computer properly through the operating system, and then turn off any external
devices.
4. Disconnect the power cord from the power outlet, and disconnect any external devices.
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.
5. Remove the computer from the stand and lay the computer down with the right side up.
6. Remove the computer access panel and back I/O panel. See
Removing and replacing the access
panel on page 8.
WARNING! To reduce risk of personal injury from hot surfaces, allow the internal system
components to cool before you touch them.
