Potential sleep issues that may require BIOS updates.
s2idle sucks, but you can make it suck less if you do the kernel param acpi.ec_no_wakeup=1 (on the P14s Gen 5 AMD, at least). This results in a normal-ish power drain in sleep mode and the laptop no longer gets hot. I haven't got a hard number to give you, but it doesn't self-drain in several hours.
