According to one embodiment, an electronic apparatus includes a first unit and circuitry. The first unit includes first and second sensors and a wireless device. The first sensor detects approach of an object. The second sensor detects whether the first unit is open or closed. The circuitry reduces transmission power of the wireless device when the first sensor detects approach of the object, and not to reduce transmission power when the second sensor detects a change from an open state to a closed state and the first sensor detects approach of the object.
