Actually, it's the 100% charge state that is bad for LiIon. But a 
charge/drain cycle will likely wear the battery out even faster - LiIon 
batteries wear model is based on usage time. A 90% charge is ideal for 
long term storage - or for someone who leaves the laptop plugged into AC 
power most of the time.

As far as software controls, I'm not familiar - but one thing that works 
in any OS is to simply remove the battery when on AC power.
