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:

•Keep the battery pack away from fire.

•Do not expose it to excessive heat.

•Do not expose it to water or rain.

To remove 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.
