Replacing a memory module

Before you start, print these instructions.
Increasing memory capacity is an effective way to make programs run faster. You can increase memory
capacity by replacing or adding a memory module.
Note: The operating speed of the memory module has dependency on the system configuration. In some
conditions, the memory module in your computer might not be able to operate at the maximum speed.
Attention: Before you start installing a memory module, touch a metal table or a grounded metal object. This
action reduces any static electricity from your body. Static electricity could damage the memory module.
To replace a memory module, do the following:
1. Disable the built-in battery. See "Disabling the built-in battery" on page 71.
2. Close the computer display, and turn the computer over.
