Disable USB charging

I bought a laptop recently.  It has not wrong to write home about.  However, its battery is a bit funny.  It keeps draining when it is off from the main.  It turns out this is normal in new laptops.  New laptops have this "useful" feature called Power-off USB charging which allows devices like phones to use the laptops battery as a powerbank.  In order to do this, the laptop is kind of "always on", and slowly drains the battery.

I don't know about others, but I personally dislike this features.  With this feature, if I don't use my laptop for a a day or two, and the laptop is off the main, the battery will become flat. This won't be the case with my old laptop.  Although the battery will still become flat eventually, it will be in a much much slower rate.

Luckily, this feature can be turned off.  Though you may need to do a bit "hunting"/research as I did.  My laptop is an Acer.  Firstly, some geniuses over at Acer decided this feature should be hidden in BIOS.  To reveal the hidden options you need to press the CTRL+S when you are in the bios.  Then, look for a very obvious option called "TBT Wake from S4 Support", and turned it off.  It is so obvious, isn't it.

 

 

 

Last step, launch "Quick Access" as an admin, then disable "Power-off USB charging" from there.

 

 

My laptop battery behaves like it "should be now. 

While we are on the topic of hidden options.  The reason I found the hidden menu was because I reset my laptop BIOS, and then Windows lost my NVMe drive.  It turned out this was because the reset re-eabled the VMD Intel feature. With this enabled, Windows needs a special driver to "see" the drive.  Once I found the option, and turned it back off, my Windows boots as it should be.
