Description Ben Engbers 2023-06-21 14:02:48 UTC 
My laptop is mostly connected to a universal USB-C dock. Until a few weeks ago I could open the lid, push the powerbutton, close the lid and the bootprocess would continue without errors.
Now, after closing the lid, I see the Lenovo logo without the rotating wheel and nothing happens. 
How can I create a log-file that can be used to discover the cause?

Reproducible: Always

Steps to Reproduce:
1. Connect the laptop to a docking station
2. Push power button
3. Close the lid
Actual Results:  
I see the Lenovo logo without the rotating wheel and nothing happens.

Expected Results:  
I would expect to see the Lenovo Logo with a spinning wheel below. After a few seconds I would expect that the boot process would continue

After holding the power button until the laptop shuts down, I can do 2 things:
- Wait a few seconds and push the power button again. I then see the Grub screen and usually the boot process continues. Sometimes however, I have to repeat the shut down.
- Disconnect from the dock and restart the machine. When I see the Lenovo logo AND the spinning wheel, I can connect to the dock and close the lid and boot continues.

Hi,
What happened a few weeks ago? Were there any updates?
If the Lenovo logo appears and then nothing happens, then it seems like it's getting stuck in firmware before it ever gets to grub.

You can try turning on lots of debugging from grub
grub2-editenv - set pager=0
grub2-editenv - set debug=all
and if this is UEFI, you can turn on shim verbosity
mokutil --set-verbosity true

Please send along any output you get.
