The DIMM slot is intended for memory modules.
Installing Memory Modules
Locate the SO-DIMM slot. Align the notch on the DIMM with the key on
the slot and insert the DIMM into the slot at a 45-degree angle.
Push the DIMM gently forwards until the slot levers click and lock the
DIMM in place.
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.
