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.

Slow WiFi after suspend/resume cycles (solved by updating the WiFi driver)
Depends if it comes with the Qualcomm NFA725A for Wi-Fi that the T14s Gen4s did - the drivers and hardware are a disaster under Linux and if it's still soldered in there's no chance of swapping it to something else.
It'll work, but be prepared for frequent disconnects and sleep issues. https://www.reddit.com/r/thinkpad/comments/1jtehta/comment/mlu3yhg/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button

Battery life with Docker running (around 3 hours) Battery life is only around 5-6 hours with moderate usage (browsing and text editor at 50% brightness).
