22. Upgrading/Modifying and Repair
Upgrades and modifications to your notebook should only be carried out by
qualified specialists. If you do not have the necessary qualifications, have the work
carried out by a qualified service technician. Please contact your customer service
department if you have technical problems with your notebook.
If a repair must be carried out, please contact only our authorised service partners.
22.1. 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. 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.
