Lately my Surface has been mysteriously shutting off way before the battery is low/critical. - ie. about 20-25%, when the concern level is 10-15% - And by shut off I mean it just stops dead, and booting up again starts from scratch.
It also has a habit of screen burn around the edges for a few minutes if I've been using a bright/white program like SAI.
And now that I've started it up after the most recent pop, the screen is flickering while on power.
I really don't want to have to replace my Surface. I just bought a new desktop. That's enough money burning for a while.
