How to prevent the computer from going to sleep mode (power saving mode)

1. The problem

During long computer tasks like a big file copy or download, the computer might enter its idle mode, interrupting the operation.

In the best case the operation will proceed when the user moves the mouse or presses a key to wake up the computer.

But there are cases where the operation cannot be resumed or there are even data loss. For example if your are formatting or repartitioning and external USB disk or moving files to a network drive via wifi.

You can go to the Windows system settings or to the Mac system preferences to disable the automatic power down sleep, but then you must revisit those settings to revert it to the normal operation.

2. The solution

I was frequently facing this problem and I wanted a more quick and easy solution, so I provided a "Power settings" tab in the configuration of the StarMessage screensaver.

With the power settings you can temporally disable the power saving mode for 2 or  8 hours. This will give your task enough time to complete what is being done. Then, automatically the power settings go to the normal operation, so that you do not have to spend time on this again.

There is also the option to permanently disable the power saving mode (for indefinite period of time). In that case you will need to revisit the screensaver's power settings to turn it off when the time-consuming task is finished.
