Removing and installing memory modules

Mainmemory

Memoryexpansion

The installation and removal of memory modules in one of the two slots

should only be carried out by an authorised technician.

The notebook will not start without memory modules, as no ﬁxed RAM is installed.

Your notebook supports dual channel DDR3 technology.

The dual channel 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 conﬁguration of 4 GBytes, 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 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

► Switch your notebook off and unplug the mains adapter from the mains outlet.
