Abstract
When a host PC acts as a host and communicates with a portable electronic apparatus, the portable electronic apparatus can release connection between the portable electronic apparatus and the host PC in no response to the host PC and in accordance with an amount of remaining power of a rechargeable battery. Also, the release of the connection between the portable electronic apparatus and the host PC results in that it is possible to avoid an access error for an HDD due to a shortage in the amount of remaining power of the rechargeable battery, and thus it is possible to prevent media data from being damaged due to the shortage in the amount of remaining power of the rechargeable battery.
