[nvda] Re: followup: nvda and battery power

well my manuals say once a month I probably don't do this.
however if you slag off you will be rewarded with a dead battery.
And deep charging will not fix it.
So once you are down the slippery road to no battery then you are screwed prity 
much.
I try to discharge once/twice a year.
I just did a discharge last month.
