I have FreeBsd 13.1 installed on a Thinkpad T61p laptop. I try to make
hibernate work so it can save power between uses.

If I type `sudo zzz`, it successfully goes to hibernate mode. When I
open the lid again, I can hear the computer is waking up. However the
screen does not come back. I can type blindly `sudo reboot`, which
will bring back the screen to show the shutting down messages.

I wonder what kind diagnostics I can do and how to fix this issue? Thanks!
