I'm still fairly new so forgive me if this has already been addressed:
My battery went down to the bear minimum and the wireless was automatically switched off (which makes sense). However, when I plugged in the power cord, my BB would still not let me use the wireless function until it had been charged to a certain level--has anybody else encountered this?
I thought this was a bit irritating as I waited for my battery to be adequately charged, but I learned my lesson!
