chapter yourself.

If you remove and install components without consulting the Hotline/Help Desk, then the
warranty of your notebook will be voided.
Notes on installing and removing boards and
components
● Switch the notebook off and pull the power plug out of the mains socket.
● Remove the battery.
● Take care when you use the locking mechanisms on the battery and any other component.
● Never use sharp objects such as screwdrivers, scissors or knives as leverage to remove
covers.
Boards with electrostatic sensitive devices (ESD) are identifiable by the label shown.
When you handle boards fitted with ESDs, you must, under all circumstances, observe the following
points:
● You must statically discharge yourself before working with boards (e.g. by touching a grounded
object).
● The equipment and tools you use must be free of static charges.
● Remove the power plug from the mains supply before inserting or removing boards containing
ESDs.
● Always hold boards with ESDs by their edges.
● Never touch pins or conductors on boards fitted with ESDs.
