Will Halley's comet ever burn out?

Halley's (not Hailey's) will in time lose its ice and become a dry rocky like “dead comet orbiting the sun. As it loses its ice it will no longer generate a tail and no longer be a comet. This could happen in as little as 100,000 years or so because it loses ice every time it passes close to the Sun.
