Dell Vostro 15 3510 Statement of Volatility

Statement of Volatility – Vostro 15 3510 CAUTION: A CAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the problem. The Vostro 15 3510 contains both volatile and non-volatile components. Volatile components lose their data immediately after power is removed from the component. Non-volatile components continue to retain their data even after power is removed from the component. The following Non-volatile components are present on the Vostro 15 3510 system board. Table 1. List of Non-Volatile Components on System Board

CAUTION: All other components on the system board lose data if power is removed from the system. Primary power loss (unplugging the power cord and removing the battery) destroys all user data on the memory (DDR4, 2400/2667 MHz). Secondary power loss (removing the on-board coin-cell battery) destroys system data on the system configuration and time-of-day information. In addition, to clarify memory volatility and data retention in situations where the system is put in different ACPI power states the following is provided (those ACPI power states are S0, S1, S3, S4 and S5): S0 state is the working state where the dynamic RAM is maintained and is read/write by the processor. S1 state is a low wake-up latency sleeping state. In this state, no system context is lost (CPU or chip set) and hardware maintains all system contexts. S3 is called “suspend to RAM” state or stand-by mode. In this state the dynamic RAM is maintained. Dell systems will be able to go to S3 if the OS and the peripherals used in the system supports S3 state. Win10 support S3 state. S4 is called “suspend to disk” state or “hibernate” mode. There is no power. In this state, the dynamic RAM is not
