Power Triggers is a small utility for running batch file on suspend(sleep) and/or run another batch on resume(wake). Both are optional, which means you can either choose to run batch file before sleep or after wake or both.
It sits in the system tray and takes only 4Mb of system memory. It can come useful on wide range of issues, such as, removing errors on suspend and resume. Technically you can perform any action before sleep and after wake up with this tool.
