Your notebook supp orts dual channel technology if two DDR3 memory modu les
are installed. Fujitsu Technology Solutions recommends installing two identica l
memory mo dules in ord er to achieve the best syste m performance.
If you are asked by the Hotline/Help Desk to remove and install the memory
modules yourself, proceed as follows:
Pay at tention to the relevant safety notes provided in th e "Important notes" chapter.
The notebook must be switched off when installing/removing the memory
modules, it must not be in Suspend mode.
Only use approved memory expa nsion modules in your notebook
(see Section "
Technical data", Page 29).
Never use force when installing or removing memory modules.
Make sure that foreign o bjects do not fall into the memory expansion compartment.
Individual components (e.g. the processor heat sink) can become very hot
during operat ion. Therefore, we recommend that you wait one hour after
switching off the notebook before removing or installing the memory modules.
Otherwise, there is a risk of suffering burns!
