T 4.9 Disruption of the internal power supply
Use of a mobile IT system, e.g. a laptop, pre-supposes that the system has a
power supply unit independent of the mains. Such a unit, which generally uses
rechargeable batteries, will usually last for several hours of operation. After
that period, sufficient power supply is no longer ensured so the IT system will
have to be de-activated or connected to the supply mains. The majority of
mobile systems constantly check the supply voltage and indicate any critical
voltage drop. If such a message is disregarded, the system may all of a sudden
become inoperative, and the results of the latest transactions that are stored
only in the main memory, will be lost.
