18.1. What To Do In Case of Hardware Problems
Malfunctions can sometimes have quite trivial causes, but they may also be the re-
sult of defective components. We have included a brief troubleshooting guide be-
low which may help to solve any problems.
If these tips don’t do the trick, then we’ll be more than pleased to help you out. Just

18.2. Find The Cause
Start by carefully checking all the cable connections. If the indicator lamps are not
on, ensure that the Notebook and all peripheral devices are connected to the pow-
er supply.
• If you are in battery mode, connect the Notebook to the mains adapter and
check that the battery is charged.
• If you wish to operate the Notebook using the mains adapter, disconnect the
mains adapter from the socket and connect an electrical appliance such as a
lamp to the same socket to test it. If the lamp does not work either, seek the ad-
vice of an electrician.
• Turn off the Notebook and check all cable connections. If the Notebook is con-
nected to peripheral devices, check all cable connections. Do not swap around
the cables for the various devices, even if they look alike. The pin assignment
within the cables may be different. Once you have ensured that the device’s
power supply is functioning and all connections are intact, then switch the
Notebook back on.
