Expected Results

What is reasonable?
Note that we ask for you to judge whether the system behaviour is 'reasonable' or not, without prescribing the exact outcome. If some aspect of the system behaviour is surprising or confusing to you, it is probably worth pointing out.

• Reasonable behaviours might be:
  1. The system is working as normal.
  2. The external display is working fine.
• Unreasonable behaviours would include:
  1. Not resuming.
  2. Blank screen.
  3. Crashing when the lid is opened
  4. Resuming and immediately shutting down
  5. Slow and flickery resume
