I've tried suspending with pm-suspend, shutting the lid and pressing
the power button as both are set to suspend in power management
settings. And I tried resuming opening the lid and pressing the power
button.
All methods with the same result, the laptop is suspended but when I
want to resume the power light turns on but the screen is black and I
cannot connect over ssh either. So it's worse than a graphics related
issue.
Following the steps in DebuggingKernelSuspend page I was able to resume
after suspending with the command:
`sudo sh -c "sync && echo 1 > /sys/power/pm_trace && pm-suspend"`
WiFi wasn't enable after resuming but I was able to enable it manually .
I'm attaching my *wakeup* and *dmesg* as advised by the debugging guide.
