| description | To provide an information processing apparatus and a power supply control method which can prevent the increase in frequency of activation of a specific type of storage unit while reducing power consumption.SOLUTION: An image forming apparatus 100 comprises: an SSD 7 which includes a flash memory 11 and writes data into the flash memory 11 at the time of switching between a first state of being supplied with power and a second state of being not supplied with power; a power supply control unit 32 which performs power supply control including a first step of supplying power to the SSD 7 in response to receiving an access request to the SSD 7 being in the second state and a second step of stopping power supply to the SSD 7 after the passage of a preset waiting time following the end of access processing performed on the SSD 7 in response to the access request; and a setting processing unit 34 which sets the waiting time on the basis of a frequency of execution of the power supply control.SELECTED DRAWING: Figure 2
【課題】消費電力を低減するとともに、特定種類の記憶部における起動回数の増加を抑制可能な情報処理装置、及び給電制御方法を提供すること。【解決手段】画像形成装置１００は、フラッシュメモリー１１を有し、給電を受ける第１状態と給電を受けない第２状態との間の切り替わり時にフラッシュメモリー１１へのデータの書き込みを行うＳＳＤ７と、ＳＳＤ７が前記第２状態である場合においてＳＳＤ７へのアクセス要求を受け付けた場合に、ＳＳＤ７に給電する第１工程、及び前記アクセス要求に応じたＳＳＤ７へのアクセス処理の終了時から予め設定された待機時間の経過後にＳＳＤ７への給電を停止する第２工程を含む給電制御を実行する給電制御部３２と、前記給電制御の実行頻度に基づいて前記待機時間を設定する設定処理部３４と、を備える。【選択図】図２ |
