Refer to the enclosed Instruction Manual for Safety and Comfort for
detailed precautions and handling instructions.
Charge the battery pack only in an ambient temperature from 5 through 35

shortened.

remain. If you continue to use the computer while the DC IN/Battery
indicator flashes, the computer enters Hibernation Mode so that you do not
lose any data, and automatically turn itself off.
