The difference is probably the nature of the suspend. Suspend to disk is 
when the system writes the memory to disk (swap area usually) and then 
turns off completely. No power used and no lights flashing.

Suspend to memory is a different sort of hibernation where the system is 
put to sleep but the memory is kept powered up to retain its contents. 
This mode does require some power to keep the memory powered and usually 
has some kind of flashing light. The benefit of this approach is it is 
much faster to suspend/resume then the to-disk approach.

So, how did you suspend the machine in each case ?
