Hi ther! My Display on my SP4 is pressed out on the left side by a bloated accu. So I would like to Change the accu by myself, there are several Videos on YouTube so I think I can do it and it will cost me 60$ or so. But Im afraid when I heat the Display to loose it the accu can explode. What do you think? Also to remove the old accu they all heat up the case. So will there be a Risk for me? Thank you!
