Although it is already a portable software, it could be an interesting application.

It stops a computer from going into hibernation, or to allow only partial hibernation. Really usefull at times.

And it is not open source but free to distribute (but not to sell)...

Please mention the homepage of the utility at least...

Just searched to see if anyone requested this before and found this thread.
I 2nd it.
