Installing memory module
There are slots for two memory modules, one over the other. The 
procedures are the same for installing either module.
1. Set the computer to boot mode and turn the computer’s power off. 
Make sure the Power indicator is off. Refer to the Turning off the power 
section in Chapter 3, Getting Started.
2. Remove AC adaptor and all cables connected to the computer.
3. Turn the computer upside down and remove the battery pack. Refer to 
Replacing the battery pack section in Chapter 6, Power and Power-Up 
Modes, for details.
4. Loose a screw securing the memory module cover. The screw is 
attached to the cover to prevent it from being lost.
5. Slide your fingernail or a thin object under the cover and lift it off.

6. Fit the memory module’s connectors into the socket at about a 45 
degree angle and push the module down until latches on either side 
snap into place.
Align the notch of the memory module with that of the memory slot and 
gently insert the module into the slot.

Align the grooves of the memory module with the locking tabs of the 
connector and insert the module into the connector firmly. If you find it 
difficult to install the memory module, try to adjust the tabs of the connector 
with a pen tip or other tools. Make sure to hold the memory module with 
your fingers on the side edges (sides with grooves).
