The installation and removal of memory modu les in one of the two slots
should only be carried out by an auth orised technician.
The no tebook will not start without memory modules, as no fixed RAM is installed.
Your notebook supports dual channe l DDR3 technolo gy.
The dual c hannel DDR3 technology can only be used with two identical memory
modules. When two different memory modules are installed, only "single channel"
mode is supported. This reduces the performance of your notebook.
With a memory c onfiguration of 4 G Bytes, the visible and usable
main memory may be reduced to 3 GBytes (depending on notebook
configuration and the operating system used).
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 m ode.
Only use approved memory expansion modules in your notebook
(see Section "
Technical d ata", Page 26).
Never use force w hen installing or removing memory modules.
Make sure that foreign objects do not fall into the m e m ory expansion compartment.
Individual components (e.g. t
he processor heat sink) can become very hot
during operation. Therefore
, we r eco mmend that you wait one hour after
switching off the notebook b
efore removing or installing the memory modules.
Otherwise, there is a risk o
f suffering burns!
As some non-ESD safe co mpone
nts are exposed, please observe the s ection "
