Moving your computer
Take the following precautions before moving your computer.
1.Back up all files and data from the hard disk drive. There are a variety of backup programs available commercially. Your operating system also might have a backup program that you can use. Lenovo provides the Rescue and Recovery program to help you back up and restore data. See “Performing backup and recovery operations” on page 90 for more information.
2.Remove all media (diskettes, compact discs, tapes, and so on) from the drives.
3.Turn off the computer and all attached devices. Your hard disk drive automatically parks the read/write head in a nondata area. This prevents damage to the hard disk drive.
4.Unplug the power cords from electrical outlets.
5.Disconnect communication cables, such as modem or network cables, from the outlets first, and then disconnect the other ends from the computer.
6.Note where any remaining cables are attached to the computer; then, remove them.
7.If you saved the original shipping cartons and packing materials, use them to pack the units. If you are using different cartons, cushion the units to avoid damage.
