4. Gently separate the case from the display, taking care to not separate the pieces so far
that tension is placed on the connecting cable (4). Do not unplug the connecting cable.
5.2 Real-time clock battery
The battery supplies power to the real-time clock (RTC) and maintains the UEFI settings in
the BL2 ...1000/2000/7000 when the system is not connected to a 24 V DC power source.
If power is removed while the battery is discharged or removed, any user-defined UEFI
settings will be lost, and a “CMOS checksum error” message appears once power is
restored.
To account for user-defined UEFI settings, it is recommended that they be recorded through
photos or a separate document before the battery is depleted or removed. Store the photos
or documents on a different device so they are accessible in the event of a boot failure.
The battery is type BR2032. The battery has a typical life of five years and may require
replacement.
