Abstract
An electronic device includes a port for connecting the electronic device to other electronic devices and a moisture detector configured to detect an electrically conductive liquid in the first port. The moisture detector is configured to maintain a voltage on a first electrical contact of the port and to detect a short circuit between the first electrical contact and a second electrical contact of the port. The moisture detector determines that the electronic device has been exposed to an electrically conductive liquid if the monitor module detects the short circuit. The moisture detector may also put the electronic device into safe mode if it is exposed to an electrically conductive liquid.
