See, most desktop motherboards have a small battery that supplies power to the BIOS even when the machine is turned off. This battery might last two years or it might last 10, but when it fails, you'll often see an error message like the one above.
To make the scones, in a large bowl, combine flour, brown sugar, oats, baking powder, orange zest, and salt. Mix well. Cut frozen butter into very small cubes. Using two forks, quickly and thoroughly mash butter into the flour mixture, until the mixture resembles coarse crumbs.
1 While the scones are chilling, preheat the oven to 425F. 2  Bake the scones for 20 to 25 minutes, or until they're golden brown. When you pull one away from the others, it should look baked all the way through; the edge shouldn't look wet or unbaked.  Remove the scones from the oven, and cool briefly on the pan.
