I fired up my Switch 10 for the first time in a few months. it boots fine, but when I go to do anything, the screen blanks. I can awaken it with the Windows key, but all I can do is toggle it between the login screen and the regular screen... but the first keystroke blanks the screen again.
if i use JUST the touchscreen, it seems more or less normal. (I'm running Windows Update now this way. The last full update run was in March. )
is this a known problem?
