PC still automatically enters S3 suspend while in the process of manually installing updates (or at least the downloading step before installation)

Comienza con el flujo de instalación manual de mintUpdate y la transferencia a Synaptic descrita en los logs; después, sigue cómo la aplicación gestiona las fases de descarga e instalación. Reproduce el problema con la suspensión automática S3 activada y un timeout corto. Se considera terminado cuando el sistema permanece activo durante toda la descarga y la instalación de la actualización, y el flujo existente de actualización e instalación sigue completándose con normalidad.

Describe the bug
When manually installing updates, the PC is still able to automatically enter S3 suspend.

That being said, it wasn't actually installing updates when it entered S3 suspend, rather it was still downloading them before the actual install process, so perhaps this makes a difference.

To Reproduce
Steps to reproduce the behavior:

1. Have S3 suspend enabled in your PC's BIOS／UEFI (a lot of newer laptops lack this function, no idea about newer desktops)
2. In Mint's power options, have it set to automatically suspend after a period of time
3. In mintUpdate, select a bunch of updates and install them
4. Assuming that your internet is slow enough, the download is large enough, or the suspend time-out is short enough, you should see that your PC will enter S3 suspend even though the PC was in the middle of installing updates (or rather downloading the updates for installation)

Expected behavior
Installing updates should prevent the PC from entering S3 suspend, especially when you're manually installing updates rather than automatically.

Additional context
This was discovered on a Thinkpad T420. In terms of modern laptops, I can at least say the Framework Laptop supports S3 suspend in its BIOS／UEFI.
