Hi All I have an Asus F505ZA, 15.5" laptop running Ubuntu 20.04. It seems to choke when I am using several apps and browser tabs open and just stops responding. I have to do a hard shutdown and reboot. It came w/ 4GB RAM and I thought that upgrading that would help so I have a 16GB stick to install into the expansion slot. I've done this on several laptops as well as replacing SSD and HD. The most difficult was my old TiBook but I succeeded. However, Asus made adding RAM not an easy thing as evidenced in this video https://www.youtube.com/watch?v=9lyEEAZdYwo  and I am not confident about doing the job so I'm looking for a guru to whom this is easy, to install the RAM. I'll pay for the time. Anyone interested? Hope all of you are safe and protected! Best Brian --
