Here is the danger of this bug on a laptop (as I've experienced):

The system, from all appearances looks powered down (with the exception of the power indicator which remains lit on my laptop). Unfortunately, the power indicator is not in a conspicuous place which means that in order to *verify* the system is off, I have to lean over and look at the side of the laptop.

When a user gets into the habit of a system just working, checking the power indicator slips the mind. Hence, a powered on laptop may be placed inside a tightly insulated laptop bag. When this happened to me, I didn't discover it for about 2 hours. When I went to take the laptop out of the bag, the fan was now running trying to keep the internals cool, but the bag was insulated (padded). This resulted in the system being so hot that I could not even touch the keyboard in places without getting mildly burned.

I have no idea what will happen to a discharging lithium battery that is being heated rather than cooled in that situation, but I imagine there may be a component of definite risk to a system.
