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 conguration. 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 59.
2. Close the computer display, and turn the computer over.
3. Remove the base cover assembly. See “Replacing the base cover assembly” on page 61.
