Abstract
It is provided a computer comprising a nonvolatile memory for storing data, a control processor for controlling the saving of data into the nonvolatile memory, and a battery for supplying power to the computer in case of a failure of an external power supply, wherein the control processor checks a charge amount stored in the battery, calculates an amount of data which can be saved in the nonvolatile memory by the battery in case of a failure of the external power supply based on the checked charge amount, and saves data excluding the amount of data that can be saved, out of data which should be saved into the nonvolatile memory, into the nonvolatile memory in advance.
Claims9
A computer comprising
- a nonvolatile memory for storing data,
- a control processor for controlling the saving of data into the nonvolatile memory, and
- a battery for supplying power to the computer in case of a failure of an external power supply,
- wherein the control processor:
- checks a charge amount stored in the battery;
- calculates an amount of data which can be saved in the nonvolatile memory by the battery in case of a failure of the external power supply based on the checked charge amount;
- and
- saves data excluding the amount of data that can be saved, out of data which should be saved into the nonvolatile memory, into the nonvolatile memory in advance.
A data saving method executed in a computer including a nonvolatile memory for storing data, a control processor for controlling the saving of data into the nonvolatile memory, and a battery for supplying power to the computer in case of a failure of an external power supply, the data saving method including the steps of:
- checking, by the control processor, a charge amount stored in the battery;
- calculating, by the control processor, an amount of data which can be saved in the nonvolatile memory by the battery in case of a failure of the external power supply based on the checked charge amount;
- and
- saving, by the control processor, data excluding the amount of data that can be saved, out of data which should be saved into the nonvolatile memory, into the nonvolatile memory in advance.
