pushing the button in the back to off doesn't work sometimes. the nas just doesn't shut off. how long are you supposed to wait? 30 mins? no, still won't shut down.
luckily, I found out that under maintenance --> restart, there is an option to shut down. Doing that from the software was able to shut down immediately.
however, when I tried to turn it back on, pushing the button to on did nothing. I ended up unplugging the power cord and replugging it in order to get it to work.
BTW, this is fw 1.09 in the blue interface for LS-WTGL.
