Japanese Patent JP2016015807

A

PROBLEM TO BE SOLVED: To prevent breakage of an electronic apparatus due to a short circuit between a terminal used for charging of a secondary battery and a peripheral conductive material when charging for the secondary battery built in the electronic apparatus is performed.SOLUTION: An electronic apparatus repeats a behavior of performing charging of a secondary battery for a charging timer time t8 when power is supplied from a power supply adapter, and subsequently stopping the charging for a stopping timer time t9. During power supply to the electronic apparatus, the power supply adapter repeats clocking of a protection timer time t6(t8
