Upgrades and Repairs
• Only a qualified Service Engineer should perform upgrades
and repairs to your notebook.
• If you do not have the necessary qualifications, go to an ap-
propriate Service Engineer. Please contact the Service
Centre if you are experiencing technical problems with your
notebook.
• Please contact our authorized Service Partners exclusively
in the case of a necessary repair.
Notes for Service Engineers
• Before opening the housing, disconnect the notebook from
all power sources and remove any connecting cables. If the
notebook has not been disconnected from the power outlet
before being opened, there is a danger of severe electric
shock. There is also a risk of damage to the components.
• Internal components of the notebook may be damaged by
electrostatic discharge (ESD). Perform system upgrades
and changes in an ESD-protected work area. If no such
work area is available, wear an antistatic wrist strap or
touch a highly conductive metal object. Your service center
can repair damage sustained by inappropriate handling for a
fee.
• Use only original spare parts.
Notes on Laser Radiation:
• Laser devices of Laser Class 1 to Laser Class 3b may be
used in the notebook. Where the notebook housing remains
closed, the device meets the requirements of Laser Class
1. By opening the notebook housing you will gain access to
laser devices of up to Laser Class 3b.
• The CD-ROM/CD-RW/DVD/DVD-RW drive contains no user-
serviceable parts. Only the manufacturer should perform
repairs to the CD-ROM/CD-RW/DVD/DVD-RW drives.
