DANGER
If the rechargeable battery pack is incorrectly replaced, there is danger of an explosion. The battery
pack 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 battery pack, do the following:
1. Turn off the computer, then disconnect the ac power adapter and all cables from the computer.
2. Close the computer lid and turn over the computer.
3. Unlock the battery latches by sliding them to the unlocked positions
4. Insert a new battery pack until it clicks into place.
