Your notebook supports dual channel technology if two DDR3 memory modules
are installed. Fujitsu Technology Solutions recommends installing two identical
memory modules in order to achieve the best system performance.
If you are asked by the Hotline/Help Desk to remove and install the memory
modules yourself, proceed as follows:
Pay attention to the relevant safety notes provided in the "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 expansion modules in your notebook
(see Section
Never use force when installing or removing memory modules.
Make sure that foreign objects do not fall into the memory expansion compartment.
Individual components (e.g. the processor heat sink) can become very hot
during operation. 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!
As some non-ESD safe components are exposed, please observe the section
on installing and removing boards and components", Page
