Macbook trackpad not working properly

Hi All,

I recently bought a macbook 12 inch mid 2017. This fan-less design makes my macbook really hot in normal daily basic usage. Recently my macbooks trackpad starts to not function properly (lags, clicking by itself, and all the other crazy things...) after 20minutes of use. Would this problem be related to battery swelling and causing problems with touchpad? Because touchpad work just fine when i open the macbook, but after a while trackpad stops working.

Thank you
