Abstract
Embodiments herein describe methods and systems for controlling the power state of a tool. A tool is placed into an active mode upon initial power up, as typically indicated by one or more indicators. The tool is automatically placed into an inactive mode upon the expiration of a timer, if the tool motor was not activated. If the tool is activated, such as by pressing the tool switch, prior to expiration of the timer, the timer resets. A display is provided to signal the user as to the current active status and/or current mode of the tool.
