Macbook Pro 2015 continuously powered on

I have a Macbook Pro (Retina, 13-inch, Early 2015).

As it is slowly aging, I'm starting to consider leaving it continuously powered on.

Currently it stays most of the day powered on, for about the past six months.

Recently I noticed that its bottom is slightly bent. I have used it carefully through all of its life, taking good care not to over expose it to high temperatures.

Does leaving it continuously powered on entail any risk of catastrophic explosion, or further bending?

Solution 1:

This is in almost all cases caused by the battery swelling up and thus "bending" the case. The case expansion cannot in itself be caused by "overuse of fans".

You need to have your battery checked and replaced - don't wait with it. It is caused by a defective battery that swells up, and potentially could lead to a dangerous situation (such as causing a fire) if left unattended. This can happen not only when the computer is plugged in and powered - but also when the computer is turned off and not powered by an external power source!

Remember that the battery is a wearing part, and yours is probably 4+ years by now.
