If you are asked by the Hotline/Service Desk to remove and install the memory
expansion yourself, proceed as follows:
Please observe the safety information in chapter "Important notes", Page 18 .
When installing/removing memory modules, the battery must be removed from
the notebook and the notebook must not be connected to the power supply,
see
"Preparing to remove components", Page 72 .
Only use memory expansion modules that have been approved for your
notebook (see
"Technical data", Page 90 ).
Never use force when installing or removing a memory extension.
Make sure that foreign objects do not fall into the memory extension compartment.
You must open the service compartment to remove or install a memory module. On some devices,
opening the compartment may expose other components. These components should be removed
and replaced only by authorised specialists. Therefore, be sure to observe the following:
Individual components can become very hot during operation. Therefore, we
recommend that you wait one hour after switching off the notebook before removing
or installing memory modules. Otherwise, there is a risk of suffering burns!
As some components are exposed that are sensitive to static electricity, please take
note of chapter
"Notes on installing and removing boards and components", Page 71 .
