AC Adapter
The AC adapter performs two functions:
It powers the computer from an external AC source.
It charges the computer battery.
The adapter automatically detects the AC line voltage (100V or 240V) and adjusts
accordingly.
The following are recommended when using the AC adapter:
Use a properly grounded AC outlet.
Use one AC outlet exclusively for the computer. Having other appliances on the same
line may cause interference.
Use a power strip with built-in surge protection.
Connecting the AC adapter:
Insert the end of LEMO to the LEMO CONN.
Connect the end of the AC cord to the AC adapter.
Plug the AC cord into an electrical outlet.
AC Adapter Indicator:
The green LED indicates that AC power is ready.
Note:
To ensure system stability, please connect your computer to an external power source
when operating at -20 °C ambient temperature.
The battery will not be charged if an incompatible AC adapter is chosen.
