Battery charging switch
Many people are using laptops at home with AC adapters plugged in, which in particular situations is not good for the battery health. I found the 'disable battery charging' option in Battery meter very useful to preserve my battery. However, you need to turn on the computer to select it, and it resets after restarting windows as well. What I suggest here is a physical switch for the laptop that controls battery charging Enabled or Disabled (exactly like the wireless switch on most laptops). This should help you to control your battery charging without any software at any time even with a laptop turned off.
