This model of laptop currently has a few issues with power management.
We have tried using bbswitch (with patch to count AMD gpu as iGPU) to
power the dGPU off which succeeds, but then it fails to turn back on:

  ACPI DSDT info

Bug description:
  This is for people with a hybrid graphics configuration to be able to
  submit the DSDT information: This includes nVidia Optimus and AMD
  Hybrid Graphics.

  To gather information about the laptop model, install dmidecode. For the DSDT/SSDT
  files, install the acpidump and iasl tools:

      sudo apt-get install acpidump iasl dmidecode

  or (on Fedora):

      sudo yum install pmtools iasl dmidecode

  Then use the script from http://lekensteyn.nl/files/get-acpi-info.sh to create the
  tarball containing information about the laptop model, PCI hardware and ACPI tables.
  To do so, run the following commands in a terminal:

  
      wget http://lekensteyn.nl/files/get-acpi-info.sh
      sh get-acpi-info.sh

  This will create a tar.gz file that you can attach to the bug report. In the comment
  itself, please include a link to the product page of the model (if available).

  This information will allow the full development of hybrid graphics
  features for Linux. Thanks for your help!
