@arges I am also experiencing suspend issues on my XPS13 but before opening a separate bug report I would like to check if our systems are affected by the same bug.

Please check/confirm the following:

1. Is your system fails to resume or stuck during suspend? Please suspend the system using system menu (instead of closing the LID) and describe power-button light behavior. Is it turned off after 5-10 seconds?

2. Is there an external monitor? What happens if it's disconnected? (In my case connecting/reconnecting the monitor after the system is booted triggers the issues).

3. Is it a persistent behavior?

4. Is http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4.10-xenial/ still broken? (It solved the problem on my system).

Can not reproduced this issue on Precision 5510 (Ubunut 16.04, 4.4.0-21 and 4.4.0-22)

System can suspend/resume by close/open led successfully.

If a external monitor is connected, close led is not able to trigger suspend (on Precision 5510)
