Keyboard/Touchpad/Screen lock
This notebook may rarely suffer this weird problem, as well as some other Probook models. It happened to me today second time in a 1,5 years of quite frequent use. It is possible to find this solution elsewhere, but I thought it should as well be here, because when googling for it, I found this page sooner.
Symptoms: Notebook starts (fan is working, hard drive activity LED is blinking), but display is black, it does not react to any key combination or touchpad, only long press of Power button can switch it off. But don't panic, the device is not bricked. You may find, that with external monitor, mouse and keyboard it otherwise works fine (you should use external keyboard to switch the notebook off, or remotely over network, rather than using the power button). This is not OS/driver related problem, the affected parts are not working from the first phases of startup.
Solution:

  1. switch the notebook off
  2. unplug external power, remove battery
  3. press and hold power button for few seconds

That's it. After inserting the battery it will work as usual again.
