Hey folks, and many apologies if this is the wrong place to post this. Upgrading the RAM on my laptop will be my first ever PC parts purchase and upgrade of any kind, and I have no idea what I’m doing after looking through parts options. I am wondering how I can know if a given RAM stick will fit in and work with the P15, and if anyone has any options on where I should buy it from. Thanks so much in advance and sorry for such a rookie question.
