How do I fix a Thinkpad P14s to wake from sleep?

I have a Lenovo Thinkpad p14s (AMD), and I just freshly installed Ubuntu 20.04 on it. If I go into suspend and then wake my computer up, the screen with the clock appears, but I can't use the keyboard or mouse to get to the login screen to enter my password. FYI the thinkpad is also hooked up to an external monitor. Not sure if this is a bug so I decided to post here first. How can I prevent freezing on wake up from suspension?

Have you changed the sleep setting in the BIOS? That worked for me (Ubuntu 20.04.02 LTS).

Reboot.

Press Enter at the "Lenovo" screen.

Press F1 to enter the BIOS.

Change "Config -> Power -> Sleep State" to "Linux".

Press F10 to save and reboot.

Prior to this, the LED on the laptop lid stayed solid red when I suspended. Now it pulses slowly (which is what I'd expect from owning previous Thinkpads).
