DANGER
If the rechargeable battery is incorrectly replaced, there is danger of an explosion. The battery
contains a small number 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, 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.
To replace the removable battery, do the following:
1. Turn off the computer and disconnect it from ac power and all cables.
2. Close the computer display and turn the computer over.
3. Unlock the battery latch. Then remove the battery.
4. Insert a new battery.
5. Lock the battery latch.
