Removing and installing components during servicing

Removing and installing memory modules

The notebook will not start without memory modules, as no fixed RAM 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" 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).

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 "Technical data", Page 28).

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 "Notes on installing and removing boards and components", Page 24.

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

Close the LCD screen so that it locks into place.

Disconnect all cables connected to the notebook.

Turn your notebook over and place it on a stable, flat and clean surface. If necessary, lay an anti-slip cloth on this surface to prevent the notebook from being scratched.

Remove the battery (see "Removing the battery", Page 16).
