Have you tried laptop-mode-tools? Maybe this helps :)

Hello All! I have a T420 that doesn't resume when the laptop lid is opened. I put it to sleep by closing the lid. When I open the lid, the disk indicator flashes and then stops. The power button led remains pulsing as if it's still asleep. If I press the power button at this point nothing happens. Resume from sleep seems to work fine if I put the laptop to sleep via dbus with the lid still open and then resume by pressing the power button. I have tried both Stretch(stable) and testing with the same issue. I have upgraded the BIOS to the latest(and what a chore that was). I'm out of ideas. Has anyone seen this particular problem before? Any suggestions? Thanks in advance! Ryan
