To insert the drive, slide it straight into the compartment as far
as it will go; then slide it to the right until you feel it snap into
place.
Caution
Use only the appropriate Epson hard disk drives. Inserting
an incompatible drive could damage your system.
Saving Battery Power
If you are using the hard disk while the computer is running on
the battery, remember that it uses more battery power. You can
reduce the power consumption, however, with the following
conservation measures:
Define a timeout period for the hard disk through the
SETUP program. See Chapter 2 for instructions.
