Hi guys, I was wondering ifsomeone could explain to me what is the use of the empty slots on my laptop. I will attach a photo and say that my configuration is quite old (2008). I stumbled upon this curiosity when I opened the cover (I wanted to know what memory I use cause I want to buy bigger ones and just realized that I have the possibility to add some stuff). Could they be bluetooth or another wifi?
