Does the capslock light work?
Can you switch to a text console using ctrl-alt-f3?
Can you connect using ssh from another computer?
After you reboot it, what are the first lines from:
journalctl -b-1 -r
The laptop was still responsive, the three-fingered salute initiated a
reboot. Looking through the journal logs, I don't see anything related to
the display. Everything looks normal, the wireless comes up normally, and
reconnnects to the wireless. The closest complaint I could see is something
with the audio card:

Feb 29 12:38:40 linuxlaptop kernel: snd_hda_intel 0000:00:09.2: refused to change power
state from D0 to D3hot
Feb 29 12:38:40 linuxlaptop kernel: acpi device:1a: Cannot transition from D3cold to
Feb 29 12:38:40 linuxlaptop kernel: ACPI: Preparing to enter system sleep state S3
But everything looked normal, except for the display. The backlight was on,
but the entire screen was black. ALT-Fn, to switch VTs, didn't elicit a
response, but the three-fingered salute initiated a reboot. I haven't tried
to ssh in, but given that, and the following in journal:

it's fairly likely that the network was up.
