I am on power saver mode, started yesterday morning 10am, with light use, web surfing and some YouTube, till now 9pm, it's 23 hours, still have 20% battery left
try reboot your router with surface on?
when I turned on sp2 first time, I don't even see my network drive, after I rebooted router, everything works fine
still not shipped, just bought one in the store and cancelled pre order, they have a lot of 256G in stock. what's the point of pre order if you don't get it delivered on release date.
