I bought a new Z13 which is a Ryzen, I still have this issue on Windows I called up support to complain that the machine is boiling hot every morning when I take it our of my brief case. They sent a tech to replace the motherboard. Still have the same issue, not sure if I should bother calling them back. Luckily I also purchased the battery warranty (expecting this issue as I had a HP and a Thinkpad which had the same issue and I suspected it was a Windows issue) as I am sure this is destroying its life.
