In order to avoid loss of data, computer systems are often connected to a UPS which provides power backup in case of an emergency shutdown resulting from a power failure. However, as UPS units are costly, they take up a lot of physical space and can provide power for a limited period of time, it would be advantageous to improve the efficiency of UPS devices and enable to utilize as much as possible of the UPS power in order to save data to a permanent storage before shutdown. There is provided a method and system for controlling the frequency of one or more processors in computer systems, responsive to an indication of a power failure, and thereby reduce its power consumption, so as to provide more power for writing write-pending data to a non-volatile data storage.

A potential supplied from a capacitive load drive unit to one end of a respective capacitive load is switched to an intermediate potential between a first and a second power supply potentials for a predetermined period of time prior to switching the potential of the one end of the capacitive load from the first to the second power supply potential, or vice versa, which minimizes charging and discharging currents of the load, variations of the potential supplied to the capacitive load, and hence power consumption involved, without providing a charging capacitor having a large capacitance in the capacitive load drive unit.

There is provided a composite type recording apparatus restricting write operations depending on the type of a connected host apparatus, including a recording medium having a first data region, a non-volatile storage medium having a second data region and an identification information table for integrating and managing the first and second data region, an information selection section for selecting positional information having predetermined identification information from the identification information table according to the type of the host apparatus, a conversion section for converting positional information selected by the information selection section into positional information matching the first data region or positional information matching the second data region, a first write section for writing data supplied from the host apparatus in the first data region according to conversion process of the conversion section and a second write section for writing data supplied from the host apparatus in the second data region.

The invention relates to a charging control method and device, an electronic device, and a computer readable storage medium. The method comprises the following steps of obtaining a current charging parameter and a residual electric quantity of the electronic device, and determining first charging completion time of the electronic device according to the current charging parameter and the residualelectric quantity of the electronic device; obtaining estimated power consumption of the electronic device during the first charging completion time; and when the estimated power consumption is less than a preset threshold, starting a first charging mode, and when a charging parameter in the first charging mode is greater than the current charging parameter, and charging the electronic device in the first charging mode. If the estimated power consumption is less than the preset threshold, a CPU load of the electronic device is low and a power consumption rate is low so that the electronic device can be adaptively fast-charged, which means that the first charging mode is started. The charging parameter in the first charging mode is greater than the current charging parameter, and the electronic device is charged in the first charging mode so that charging efficiency of the electronic device is increased.
