I just turn my tab off then plug it into the charger.
No beeps, no screen, because it's off.
Works for me.
I stumbled onto this because my tab has the power problem. When it's asleep sometimes it won't wake up. I have to hold the power button for 12 seconds to get it to turn on. Since I started turning it off every night to charge it I don't have the power problem anymore. Well a 99% improvement anyway.
