Abstract

A method for an electronic device with pressing keys can automatically turn off power when an undesired operation occurs. A time threshold such as 3 or 5 seconds is set by a user in the electronic device. The method keeps detecting the operations of the keys. A pressing operation will be considered undesired if its duration exceeds the time threshold, and then the electric power will be automatically turned off.

Claims

1. An automatic power-off method for an electronic device having an input unit composed of a plurality of keys, the method comprising the steps of:

setting a time threshold;

counting a length of a duration of the key being continuously pressed;

comparing the length of the duration with the time threshold; and

turning off the electronic device when the length of the duration exceeds the time threshold.

2. The automatic power-off method of claim 1, wherein the length of the duration is about 3 seconds.

3. The automatic power-off method of claim 1, wherein the length of the duration is about 5 seconds.
