I have a 2017 Stealth that's out of warranty. A month or so ago, I noticed the lid would not stay closed. Suspecting the battery, it took me a few weeks to get to it, but when I took the back off the laptop, the battery had swollen to the point that sitting the laptop on the back plate left a 1/2" gap. (yup, that bad). I replaced the battery no problem. But both before I replaced the battery and afterwards, I've noticed CPU temps in certain circumstances have become volatile. Playing Doom Eternal (I have a Core with a GTX1070), the cpu gets to 80 deg C, and everything seems fine. But a Google Meet session with even 1 other person and the CPU temp is in the mid 90's instantly if I'm on the balanced power plan, switch to power saving and my CPI gets throttled and temps go down. The Meet session works just as well though, so this is my short term solution. (side note: starting with balanced and changing all the settings to match power saving <> power saving and vice versa) My question is this: Is it possible the battery swelling caused a change to the thermals in the laptop? Specifically since it obviously distorted the body prior to being swapped out (lid not staying closed) has the body perhaps lost contact with internals in places it's needed to transfer heat? And if that's the case, before I jump in, any suggestions on what to do?
