Caring for your ThinkPad computer
v Take care not to turn your computer over while the ac adapter is plugged
in. This could break the adapter plug.
v Turn off your computer if you are replacing a device in a device bay, or else
verify that the device is warm-or hot-swappable.
v If you exchange drives in your computer, reinstall the plastic bezel faces (if
supplied).
v Store your external and removable hard disk, diskette, CD, DVD, and
CD-RW/DVD drives in the appropriate containers or packaging when they
are not being used.

body. The static electricity could damage the device.
