SP4 battery life much better with Win 8.1 dual boot!!


How do you see anything on the screen with such low brightness settings? 15-28% ?? I initially had mine at 75% and liked it. Turned it down to 50% because the battery drained so fast, but it's not nearly as nice to use. I'm amazed to read that people can read at that low light level. Maybe there's another setting I need to tweak.
