Battery Damage When Using Surface Dock

My recent setup was a Surface Book I7, Surface Dock, and 2 external Acer monitors. One morning I came downstairs to find the screen of my Surface Book bulging out; you could see the battery inside. Although it was still functional, I was told by a non-Microsoft repair service (just as a free quick diagnosis, since they didn't do Surface devices) that the problem was the battery and could not be repaired. I purchased a Surface Pro 7 for Business (since I needed it to have Windows 10 Pro rather than Windows 10 Home), and while looking through the quick start instructions, I noticed that it said the following:

Battery Health

All rechargeable batteries wear out with time. To maintain your battery health and performance, follow these tips:

  • Once a month, let your battery drain below half way before charging it.
  • Avoid having your Surface Pro plugged in 24/7.
  • Store your device in a cool and dry environment.
  • If you plan to store your device for a long time, charge the battery to 50% every six months.

I think I did these most of the time with my Surface Book I7, except for #1. Because the Surface Dock uses the same port for charging & data, there was usually no choice other that to have it charge the whole time that I was using it. This is not 24/7, it is more like 12-13 hours. However, I sometimes wonder if the extra data signals being sent along with the power caused (or was at least a factor) in this incident. I have only had my new Surface Pro 7 a couple days, so I would like to avoid any excess damage if possible. Is there any way to help reduce damage without avoiding using the Surface Dock? Thanks!

    This is dangerous to use. If you are within 3 years of original purchase, you
    "should" be able to get a free replacement. Please contact support

    • ask for Surface support.
