Notes for Service Technicians
• Only service technicians may open up the Notebook housing
or upgrade or modify your Notebook.
• Use only original replacement parts.
• Before opening the housing, disconnect all power and
connecting cables and remove the battery. If the Notebook
is not disconnected from the power supply before being
opened, there is a risk that components could be damaged.
• Internal components of the Notebook may be damaged by
electrostatic discharge (ESD). Carry out repairs, as well as
system enhancements or modifications, at an ESD workplace.
If such a workplace is not available, wear an antistatic cuff
or ensure you are touching an earthed, metallic object. We
will charge for any repairs to damage caused by incorrect
handling.
