On my destop PC I can only wakeup with the (soft) power button. But as I understand that also don't works for you and you have to give some under voltage to your PC to wake it up.
I know two things which can help with suspend problems.
1) Update kernel, e.g. by installing Debian with kernel backports or the latest Ubuntu (should be 24.10 currently). Maybe that's also possible with Mint somehow. With updated kernels you have a chance that the problem is fixed.
2) Toggling the type of suspend between s2idle and deep, if possible:
If only one option is available in the cat command, you can't switch to another type. The one in square brackets is currently active. If this helps the value has to be changed in a configuration file, with the method above the value is switched back after rebooting.
