 Memory
The SO-DIMM slot is intended for memory modules.
1. Locate the SO-DIMM slot. Align the notch on the memory with the key on the slot
and insert the memory into the slot at a 45-degree angle.
2. Push the DIMM gently downwards until the slot clips click and lock the memory
module in place.
3. Follow the above procedures to install another or replace the memory if
necessary.
4. To avoid damaging the golden finger, remove the memory carefully at the same
angle it was inserted.
Important
You can barely see the golden finger if the DIMM is properly inserted in the DIMM slot.
