Any other thinkpad x1 carbon users on ubuntu 19.04 notice that the battery still drains even while the laptop lid is closed & suspended?

I updated from 18.10 to 19.04 about two weeks ago, and ever since, I've come home from the work and found my laptop burning up in my backpack with the battery drained 50% or more after half a day closed & (I assume) suspended.

I had this problem for a while with 18.10, but it went away after a thnkpad BIOS update included the linux sleep state.

Thanks in advance

    Are you certain that the laptop was in fact suspended? Because the power statistics claims to have data points from essentially equally spaced intervals through this time. Is it a possibility that it was still powered fully on, with the screen off? – vidarlo Jul 09 '19 at 04:06
  • Is there a way to check a log of suspensions/resumes to verify? – amamparo Jul 09 '19 at 05:12
  • I saw the same on 19.04, if you check power settings, there is no sleep on lid close – marosg Jul 09 '19 at 06:14
  • check your logs with dmesg to see if it went into suspend. dmesg | grep sleep – holmberd Jul 09 '19 at 13:08
