Hi, Not sure if this is an issue, or just not compatible with the SP3.... Basically, there's two things I've noticed, the settings in PC Settings for auto adjust brightness is dimmed out and not active... Is this not possible on the SP3 or do I need to adjust a setting to enable it..? Also... in the system tray when you click on the power status I get a percentage but don't get the guestimate as to how long the system thinks I have remaining in minutes/hours..? I've also noticed I'm not getting anywhere near eight hours... About 4ish before I need to connect it up again...? I know that power demands varies immensely depending on usage, but still would like to have the guestimate if I can.... Anyone help with these settings/issues..? Cheers!
