HP m7 j020dx LapTop
Product number: E4S19UA#ABA
Purchased it in 2013

I believe according to the specs it has two memory module slots presently with 2 memory modules at 4 gigs each total 8 gigs.
I also believe it is expandable to 16 gigs which I would think is two modules at 8 gigs each.
I think the list below states the memory modules that can be used.\

I'm guessing here so I need a little bit of assistance please.
Does the chart (pic) show what memory modules of 8 gigs that can be used and if so how do I know what to purchase from this picture showing the list of memory modules.

It is running slow for the past couple of years. I have plenty of hard drive space available; about 600 gigs so that is not the slowdown.

I have a while back run some programs to rid it of unnecessary files etc but still runs slow and takes forever to boot up (almost 15 minutes) where the task manager finally shows below 80% on the disk usage.

Thanks for the help.
