ABSTRACT:
A data terminal, such as a personal digital assistant, personal computer, pager or other such device has a persistent memory (11), a non-persistent memory (12) including a memory item (15 or 16) and an indicator (17 or 18) indicating whether the memory item has been stored in the persistent memory. The data terminal has a power supply (29), a power fail detector (50) for detecting an imminent power failure in the power supply and a switching element (34) coupling the non-persistent memory (12) to the power supply. The switching element causes the power supply to supply power to the non-persistent memory when the indicator indicates that the second memory item has not been stored in the persistent memory and discontinues supply of power to the non-persistent memory when the power fail detector detects an imminent power failure and the indicator indicates that the second memory item has been stored in the persistent memory.
