So my Laptop is a Lenovo Ideapad 300-15ISK, i got it back 2016, on task manager it says it is got 4 ram slots but when i open the panel on the back i visibly only see 2 ram slots, no they don't stack and would they be deeper on motherboard or under more panels? and second question i am not sure if this is the right laptop i bought when i lok up the model, it comes up with a all black frame laptop, all black inside frame and black keyboard, mine has a silver lid, black screen perimeter thingy, black keys but rest is silver. Is this how it is under where the Laptop details are it says it is a Ideapad 300-15ISK (80Q7) is it because the ones now are newer? and is task manager stuffing up? because i don't see aa 3rd and 4th slot. thanks!
