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: Do not touch the contact edge of the memory module. Otherwise the memory module might get
damaged.
To replace the memory module, do the following:
1. Disable the built-in battery. See “Disabling the built-in battery” on page 76.
2. Ensure that the computer is turned off and disconnected from ac power and all cables.
3. Close the computer display and turn the computer over.

in the memory slot and cannot be moved easily.
