how to tell when the heatsink go bad

Heatsinks themselves don't go bad. They are simply pieces of metal. The fans attached to them can go bad. Signs include not turning at all or very slowly and making unusual noises.

Also, the thermal compound used between heatsinks and processors can dry out and need to be replaced.

So, what problem are you having?

That sounds like the heatsink/fan assembly (the fan part) isn't working properly and the system is shutting down due to overheating.

As it's a laptop you will void your warranty if you try to replace it.
Take it in for a service and get them to have a look at it for you
