   on a slightly unrelated note
   
   i'm trying to troubleshoot two issues with my T480 that popped up at the same time, a couple days ago:
   
   • it sometimes won't wake up from suspend, especially after being transported
   • even if not being moved, it randomly crashes and spews garbage onto the screen (and any external screen that might be connected). (although i'm suspecting it's not that random after all, it happened while typing at least twice)
   • in both cases it will boot just fine after holding down the power button
   
   i'm suspecting some RAM connection issue, but how would i reliably reproduce this? yanking out a RAM stick under power doesn't seem like a good idea…

     i would first:
     - reseat ram
     - run memtest
     then if they still happen:
     1. change linux suspension type (and/or check the bios for suspend/sleep support options since that is a thing)
     2. try to test with a different OS (or linux distro)
     
     if it still happens, logs would probably be needed then

     @theking@mskey.nekomimi.party already reseated RAM, cleaned the slots with canned air, and ran memtest (only one pass though)
     
     suspend type is normal suspend to ram, i've never set up swap on this machine (don't really need it with 32 GB of RAM)
     
     i guess i'll try booting a live system and travelling around with that suspended next. maybe run another memtest overnight as well
