• 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 battery or 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 75.
2. Ensure that the computer is turned off and disconnected from ac power and all cables.
3. Close the computer display and turn the computer over.
4. Remove the bottom cover. See "Replacing the bottom cover" on page 76.
5. Disconnect the main battery connector.
