firstly, tlp is a powerful tool, but you need to configure it before letting it loose, identifying components you don't need and can be powered down, figuring out power limits, etc. that's too much work for me. also, if you're on ppd, maybe try switching it with tuned and tuned-ppd, which are now default on Fedora.
can't help with your specific machine, here's what works for me. what I want is a powerful laptop that works as a workstation when on AC, sips power when mobile, and has no significant power drain when left in standby for days. so:
-
using Plasma, as it has (among many other benefits) different power settings for docked and on battery. so it has generous power settings on AC and then rather conservative ones on battery, and
-
implementing
suspend-then-hibernate. the laptop sleeps normally when not used, but if not used in an hour or so, it suspends to disk and turns off all power - no more battery drain. on powering up, it resumes from disk back to how I left it - faster than cold boot!
this brings it super close to stuff I had back in the macOS days - a laptop that I can leave for days and when I pick it up heading out the door I know it has a charge.
