Prerequisites for the procedure

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, refer to the instructions for the computer:

•“Lenovo V480 and V480c” on page 33

•“Lenovo V580 and V580c” on page 34
