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
Thanks in advance!
