Disconnecting your car adapter
The car adapter can be disconnected from your computer at any time,
even while your computer is operating. However, if you do disconnect
your car adapter while your computer is running, observe the following:
•
Disconnect at the DC-in connector before disconnecting from
the cigarette lighter socket.
•
Ensure that your computer has an internal battery installed.
Operation during engine starts
Voltage variations and spikes from your vehicle’s power supply during
engine starts can disrupt the operation of your SPARCbook. As a
precaution, disconnect your car adapter from your SPARCbook before
starting the engine, following the instructions in the previous section,
and reconnect once the vehicle’s engine is running.
