How do I fix the laser on my GMC Redeye saw?

The laser on my GMC (Australian) Redeye circular saw just stopped working one day. Is there a part I can replace, or will it 'explode' into little pieces when I take it apart (had that happen more than once with power tools...)?

I live near Raleigh NC - is there someplace I can take it if I can't do it myself? Thanks!
