in theory it should work, because your computer corresponds to the same batch of serial numbers that had that issue,. But i will ask tech tomorrow just in case

I’ve run into another issue, I reset my windows to a fresh install, and now every time I close the lid of my laptop it gets VERY hot like it never turned off, what do I do
