A few years ago, I had a Thinkpad X1 with Linux which would wake up in 
my backpack every now and then, draining the battery and overheating.

Then I figured that turning on my bluetooth headphones was the trigger! 
Bah, laptops nowadays use this silly "Windows Modern Standby" which 
drains the battery faster even when it works as it should.

I switched to a System76 Lemur Pro with Coreboot UEFI firmware. It still 
drains the battery in 3-4 days while sleeping, but now at least in 
theory I could debug it myself.
