A few of us are experiencing a few issues with these laptop (I have the same exact model); it will be best to file a bug for this.
Do you mind sharing what you have done to get it to this state, I have tried kernel 4.3.x from the testing repo and the laptop will not boot. I went ahead an try kernel 4.4.x (rawhide) and the laptop boot only once and after that I have only been getting a blank screen. I am currently using kernel 4.2.300 (obsolete soon) and have to append i915.preliminary_hw_support=1 to the kernel argument; however, the touch pad works.
I have only file a bug for kernel 4.3 from the testing repo, but I hope to file all these bugs within a day or two.
