Hello,
This kind of suspend issue could be caused by many possibilities, video driver, kernel and buggy firmwares... etc.
You can first check if there is more than one graphic controller on your system, and install the corresponding driver if you do have an AMD / NVIDIA graphic card.

For more debugging instructions, please check this article:

And you will find more information for where to get help in the FAQ linked here.
