Why is NetLogo so much slower when I unplug my Windows laptop?
Your computer is switching to power saving mode when unplugged. It’s normal for this to reduce speed a little, but unfortunately there is a bug in Java that drastically slows down Swing applications, including NetLogo. One workaround is to change the power settings on your computer so it doesn’t go into power saving mode when you unplug it. (If you do this, your battery won’t last as long.) Another workaround is to run NetLogo with an option recommended by Sun, by editing the NetLogo.lax file, found in the NetLogo directory (under Program Files on your hard drive, unless you installed NetLogo in a different location).
