Solved! MSI STELATH PRO CASING WHERE THE KEYPAD IS SWELLING

[DALIGUY]

MY LAPTOP/MSI STEALTH PRO CASING UNDERNEATH WHERE THE MOUSE IS SWELLING AND IT DOES NOT SIT FLAT.
IT SITS UNDER A THREE FAN USB COOLER AND IT IS STILL SWOLLEN.
I AM HESITANT TO TAKE IT APART WITHOUT AN IDEA OF WHAT COULD BE CAUSING THIS ISSUE,
THE MAIN QUESTION I HAVE IS WHAT IS SITTING DIRECTLY UNDER MOUSE-PAD/KEYBOARD AREA?

ANYONE PLEASE??
MANY THANKS,
JACK

Likely a swelling battery which should fixed asap. A swollen li,-ion is dangerous as they can catch fire and/or explode.
