My MacBook Air is running SLOW

I’ve had this laptop since around 2019. A while back my computer started running very slow, I tried to reinstall it, completely erasing all the data but the problem persisted.

Since I’ve been around computer basically my whole life I thought it’s dust in the fan so I cleaned that up. Still no improvement.

After closer inspection I noticed something that looked like a small hole or a very small crater in my battery and one side was also very swollen, got terrified and ordered a new one, replaced it with your FANTASTIC guide but it’s still running slow.

Downloaded the TGpro after done some reading here since I’m lost…

When entering the system settings - battery i can see the battery at 100%, but when I plug it out the computer dies.

I attached an image of the TGpro. Sorry for the potato camera.

Let’s get a CoconutBattery snapshot as this looks like a power issue. The system is running in CPU Safe mode which is why the system is sluggish.

@jpmk - Sorry you got a bad battery😖 the batteries microcontroller is not working that why the data fields are messed up with NaN and just missing.

crwdns2934271:0crwdnd2934271:0crwdne2934271:0

@danj dammnnn,... that's even after I changed the battery... But i'm sure the computer behaved the same way before I did the change, but the battery was constantly at 0%

crwdns2934271:0crwdnd2934271:0crwdne2934271:0

@jpmk - There is only one cable from the battery where the batteries data passes to the main logic board. Are you sure you fully seated it? If you are then it’s the battery it’s self.


While I don’t doubt the original battery had just worn out, it wouldn’t react like this.

This is kinda embarrassing… but you where right, the cable to the battery was not plugged in properly, I was trying to be extra careful because I’ve never really fixed a laptop before, carefulness gave me a lesson.

Thanks for your help! @danj
