DANGER
If the coin-cell battery is incorrectly replaced, there is danger of an explosion. The coin-cell 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 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 the battery, or make it subject to strong forces. Battery abuse or
mishandling can cause the battery to overheat, which can cause gasses or flame to "vent"
from the coin-cell battery.
To replace the coin-cell battery, do the following:
1. Disable the built-in battery. See "Disabling the built-in battery" on page 117.
2. Close the computer display, and turn the computer over.
3. Remove the base cover assembly. See "Replacing the base cover assembly" on page 124.
4. Detach the connector
5. Install the new coin-cell battery
6. Reinstall the base cover assembly.
