[gf <1211128@xxxxxxxxxxxxxxxxxx>]

Hello,

I had the same problem on a T500 machine.
A Lenovo BIOS update solved the problem for me.

I started to play around with the sleep settings while connect to power,
battery, and closing the lid and as a workaround a logout before sending
it to sleep also works without a BIOS update.

This is a double post.

Status in “linux” package in Ubuntu:
  In Progress

Bug description:
  My T520 has stopped suspending and resuming. I close the lid and
  doesn't suspend. Not sure if this has anything to do with it, but I
  noticed it stopped suspending when I installed XMir.
