2. Remove the cover carefully, and set the cover and screw aside for later use.
∙ Follow the above procedures in reverse order to install the cover.

18 Installing Memory Module
Installing Memory Module
1. Locate the SO-DIMM slot.
2. Align the notch on the memory module with the key on the slot and insert the
memory module into the slot at a 45-degree angle.
3. Push the memory module gently downwards until the slot clips click and lock
the memory module in place.

19
Installing Memory Module
4. Install more DIMMs if necessary.
∙ To uninstall the DIMM, flip the slot levers outwards and the DIMM will be released
instantly.
⚠
Important
∙ You can barely see the golden finger if the DIMM is properly inserted in the DIMM slot.
