we are encountering unusual problems with one of our Tecra devices.

Background info:

(The Laptop is used mostly in docked mode).

Occasionaly the screen won't turn on (laptop aswell as ext. monitor) while the laptop is used in dock-mode when the system is powered on by the user.

The user is also facing this issue, when the device is used outside the dock (eg. presentations) and reputting it into the docking station.

As said, the issues arrive occasionaly and we can't spot the problem.

Things I've already did:

- Update BIOS/UEFI to newest version
- Check multiple BIOS/ Windows settings e.g. Power-Settings -> disabled most of them that could cause this weird behavior
- Checked display drivers (Intel) and updatet them to the newest (no beta drivers)

The solution now exists of powering off the device via hard reset (pressing the power button for multiple settings), restarting the system and then putting it back into the docking station.

As you can imagine, this problem is very frustrating to us when the user has worked on something important and hasn't saved his progress before leaving meetings, because he knew he will be at his office, putting his device back in, but nothing happens and we have to hard reset it.

I appreciate any kind of help.

Best regards,
