The way to defrost in a microwave is at low power, I been told.

What happens is, the first little SPOT of food that defrosts now contains water, instead of ice. Microwaves work by heating water, but they don't work so well on ice; so they are now super-heating that one spot of water. Result in burger meat, one area is entirely cooked, while the rest is frozen solid. People think it's hotspots in their oven, but it's just how this works.

Answer, go low power; that way when one section melts and heats up, it gets a chance to spread that heat out more. Turn the food over (or stir) so that the hot spots get to spread heat to different places.
