Removing and installing memory modules

System expansion Memoryupgrade Memoryexpansion Mainmemory
The notebook will not start without memory modules, as no fixed main memory is installed.
Your notebook supports dual-channel DDR2 technology.
The dual-channel DDR2 technology can only be used with two identical
memory modules. When two different memory modules are installed, only
"single-channel" performance is supported.
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
