The next time you get a bloated battery put it into a plastic bag sucking the air out and then putting it into the fridge (no colder than 34F) that will slow the chemical reaction so you can safely remove the battery before it warms up. And of course run the battery down first.
As to your problem, I would see what the onboard diagnostics tells you. Restart the system and see if you can get it to fire up. Apple messed it up so it might fail but worth the try. Press the ***D*** key to enter you may want to try the internet version as well. Review this [link|https://support.apple.com/en-us/HT202731|Use Apple Diagnostics to test your Mac] and review this guide for the other startup key options [link|https://support.apple.com/en-us/HT201255|Mac startup key combinations]. Tell us what you get for error messages.
The reason the system is slow is one or more sensors are telling SMC the system needs to run in CPU Safe Mode which cranks up the fans and lowers the CPUs clocking to prevent it from over heating.
I would inspect all of the cable connections to the logic board as well here as one could be not seated correctly or the ZIF latch is not pressing on the ribbon cable or even missing as they to tend to fly off nearer to be found! Reference this guide [guide|56210]
Hopefully it’s just a simple cable issue. Let us know how it goes! Good luck 🤞

@mfirestar - Sadly, I think you still have a TIM issue 😩

I us a loadable spray can which I load with ISO and using a soft tooth brush fully clean the green chip carrier of the paste. It doesn’t take much to mess things up.

Now jumping to your MacBook Air… swapping the SSD wouldn’t be the cause and if you had kernel virus that wouldn’t infect SMC and that would require firmware level access which only Apple has the certificate key to allow via their OS updater process. Basically very remote and you wouldn’t be the only one.
So why is my Air acting like my MacBook? Some symptoms can be caused by different problems so it’s important to fully diagnose the root issue. At this point see if your friend can run the diagnostics on this system. I would look at Activity Monitor to see what process is running hard as a badly running App can be the problem. Compare your systems besides the Apple processes what else is running that is common?

Lastly, let’s check the battery, install if you haven’t yet [https://www.coconut-flavour.com/coconutbattery/|CoconutBattery] let’s see what it tells us.
