MikeX, do you have a role within an OEM by any chance? Or is it that you are so risk adverse that you do not think that a Bio med should do anything?

The risk of a battery fire ( note, on a laptop, not a medical device) is always there, a cmos support battery carrying 35mAhr is not a major risk of fire in my experience ( I used to design and develop batteries for the Navy).

Risk assessment has replaced common sense, they should be the same, but one comes with a form to back up your thinking.
