I prefer the energy savings. 5% (I assume as a fraction of maximum power consumption) is noticeable. If your total battery lifetime is 3 hours you will get an additional 9 minutes. I'm also assuming the keyboard LEDs would come back when you start doing something, like typing, and stay on for a while before going away again. On the other hand, I'm not sure how common it is to have a keyboard attached to a laptop running on batteries... -- Hans Petter --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
