You can increase your computer memory by installing memory modules on the system board. See Specifications for information on the memory supported by
your computer. Install only memory modules that are intended for your computer.
The computer has two memory slots, DIMM A and DIMM B. DIMM A is located on top of the computer under the keyboard, and DIMM B is located on the bottom
of the computer under the memory module cover. DIMM A holds the basic memory module as configured from the factory. If you did not order additional
memory, DIMM B is empty. Generally, if you add memory, you use DIMM B. If you are upgrading memory, you may need to install memory in DIMM A and DIMM
B, depending on the extent of the upgrade.
To install a memory module in DIMM A:
1. Follow the procedures in Before You Begin.
2. Remove the hinge cover (see Hinge Cover).
3. Remove the keyboard (see Keyboard).
4. Ground yourself by touching one of the metal connectors on the back of the computer.
5. If you are replacing a memory module, remove the existing module:
a. Use your fingertips to carefully spread apart the securing clips on each end of the memory module connector until the module pops up.
b. Remove the module from the connector.
6. Ground yourself and install the new memory module:
a. Align the notch in the module edge connector with the tab in the connector slot.
b. Slide the module firmly into the slot at a 45-degree angle, and rotate the module down until it clicks into place. If you do not feel the click, remove
the module and reinstall it.
7. Replace the keyboard (see Keyboard).
8. Replace the hinge cover (see Hinge Cover).
9. Insert the battery into the battery bay, or connect the AC adapter to your computer and an electrical outlet.
10. Turn on the computer.
