  • Hopefully this will fix the sleep issues on my SP7. Loosing about 10% per hour when in sleep.
  • I installed this firmware today on my SP7 and now the screen brightness slider doesn't seem to work at all (I'm stuck at 100% brightness). I've tried toggling on and off the auto brightness adjustment to no effect. Had the same behavior with the Surface Go for several early firmware releases. It's amazing Microsoft can't get this to work consistently on their own controlled hardware.
