when i picked up my laptop (hp pavilion 16) this afternoon, it was puffy against my lap, so i looked at it and it was expanding at the bottom. i forgot to take a picture, but i looked it up and it said it could be a battery issue! i opened it up, and here is what it looks like. my dad says the battery seems fine! from the images on google, i’d also say it looks okay, but what do you guys think?
