I just upgrade my Lenovo X1 Carbon from Ubuntu 20.04.4 to 22.04. Before, I could wake up from suspend by either opening the lid or by pressing the power bottom. Now, after upgrading, I cannot wake up from suspend at all! I need to force shutdown that is very annoying.
Any idea how to fix this problem?

Security chip
also let the laptop wake up from suspend again. Not sure which downsides deactivating the chip on Ubuntu has.
