Replacing a memory module
Before you start, read “Important safety information” on page v and print following 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 the replacement, touch a grounded metal object. This action reduces any static electricity
from your body. Static electricity might damage the memory module.
• Do not touch the contact edge of the memory module. Otherwise the memory module might get
damaged.
To replace a memory module, do the following:
1. Disable the built-in battery. See “Disabling the built-in battery” on page 83.
