Before conducting any battery test, verify that all system software stored in volatile memory is protected from loss.

Before conducting any battery test, verify that all system software stored in volatile memory is protected from loss.

• A. True
• B. False
• C. Not enough information
• D. Unknown

Answer: (A)

Volatile memory (RAM) only retains data while power is supplied. A battery test involves power changes that could interrupt or drop voltage, risking loss or corruption of the software and data stored in RAM. To avoid leaving the system without its critical software or entering an unsafe state after the test, you must verify that those RAM-stored programs are protected from loss—typically by having the essential software backed up to nonvolatile storage or by ensuring power will remain available (for example, via battery-backed RAM or an uninterrupted power supply) during the test. Because preserving RAM contents during testing is a key safety precaution, the statement is true.
