4.12 Replacing the system battery
In all CIARA Astro PB60S models the battery is a custom 3 V Lithium battery model CR-2032U made by Asus that can be installed only
by CIARA. This type of battery should last at least 3 years, if the system is not in use. When the computer is plugged in, the standby
current from the power supply extends the life of the battery. If the battery wears out, your system will no longer retain BIOS
information when turned off. For example, you will get a message stating that the time and date are invalid. If this happens, you
should replace the battery, or call your CIARA service representative.
CAUTION :
There is a danger of explosion if the battery is incorrectly replaced. If it has to be replaced, it can be done only by a qualified CIARA
technician. The disposal of used batteries is subject to environment issues and this work should be done by a qualified CIARA
technician who will dispose safely of the used battery.
NOTE
The Intel TPM uses the onboard coin-cell battery (CR2032) to maintain its monotonic counters. One major function of the monotonic
counters is for anti-replay protection of the internal Intel TPM data. If the battery is removed or exhausted, the Intel TPM data will
be deleted in accordance with Trusted Computing Group guidelines. Please back-up TPM keys and data before removing the battery.
