Hi,
a few days ago, battery life (Surface Book i5, 128GB, 8GB RAM, Mod. 2015) at full charge suddenly showed not the usual 8 or nine hours, but only 2.5 hours. It was not a mistaken display: I watched it drain within this time down to 5 Percent. DIsplay says both units (Tablet + Base) are charging.
Did I miss something? Do I need to update the battery drivers (in case there's such a thing)? Please, I need an advice - I'll be in the middle of nowhere until christmas, mail doesn't reach me and I can't get to a city to exchchange the device.
I's appreciate any advice; thank you.
