DANGER
If the backup battery is incorrectly replaced, there is danger of an explosion. The backup battery
contains a small amount of harmful substances. To avoid possible injury:
• Replace only with a battery of the type recommended by Lenovo.
• Keep the battery pack away from fire.
• Do not expose it to excessive heat.
• Do not expose it to water or rain.
• Do not short-circuit it.
• Do not drop, crush, puncture, or subject to strong forces. Battery abuse or mishandling can
cause the battery to overheat, which can cause gasses or flame to "vent" from the battery
pack or coin cell.
To replace the backup battery, do the following:
1. Turn off the computer; then disconnect the ac power adapter and all cables from the computer. Wait
three to five minutes to let the computer cool.

3. Remove the battery. See "Replacing the battery" on page 67.
