purchased Acer Chromebook 311 purchased 11-26-20, noticed bottom seems warped, read could be battery, any ideas or what I need to do.  Is this dangerous, has been sitting on my desk and just went to use it this afternoon and noticed it wobbles, has not been dropped or anything.

There are other things than the battery that can cause some warpage, but the battery is usually the first thing we look at. Which model of Chromebook 311 do you have? It's likely something like CB311-xxx-xxxx. We'll want to open it up and visually inspect the battery to see if it's swollen.
