4.6.1.8 Battery
A lithium battery (3 V, 1000 mAh) ensures the retention of the internal real-time clock (RTC) and is located on the
bottom of the device as a battery tray. The self-discharge time of the battery is at least 8 years
4)
. The battery is
subject to wear and should be replaced regularly (at least after the specified service life) by changing the battery.
The battery state is determined by the system immediately after the device is switched on and subsequently every
24 hours. During the measurement, the battery is subjected to a brief load (approx. 1 second) and then assessed.
The determined battery state is displayed on the BIOS Setup screens (Advanced / OEM features /
) and in the ADI Control Center but can also be read out in a customer application via the ADI library.
Battery state
Explanation
N/A
The hardware or firmware used is too old and does not support readout.
GOOD
Data retention is ensured.
BAD
As soon as the battery capacity is recognized as BAD (insufficient), the battery compartment must be replaced.
As soon as the battery capacity is recognized as insufficient, the battery compartment must be replaced with
replacement part
"Changing the battery" on page 96
.
Data is retained by a capacitor in order to avoid data loss during battery replacement.
Information:
The self-discharge time when changing the battery is approx. 2 minutes.
4.6.1.9 Trusted Platform Module (TPM)
A Trusted Platform Module (TPM 2.0) is located on the system unit. A TPM is an additional chip integrated directly
into the system hardware that adds important safety functions to the device. In particular, the TPM enables improved
protection of the PC against unauthorized tampering by third parties. These safety functions are supported by
current operating systems, such as Windows 10.
Enabling the Trusted Platform Module
Information:
Before enabling the TPM, possible country-specific usage restrictions or regulations must be checked.
Using the Trusted Platform Module
The TPM can be used together with the drive encryption
BitLocker
in Windows 10, for example. To do this, follow
the instructions in the operating system.
Information:
If the password for data encryption is lost, it is not possible to decrypt the data, e.g. after a BIOS update
or TPM firmware update. Access to the encrypted drive is lost. Passwords must be carefully stored
and protected from unauthorized access.
