Welcome to the Linux forum Snorty!

Unfortunately problems with suspend and hibernation are very common with Linux. But fortunately everything worked fine before in your case. Therefore I have high hopes that this problem can be solved.

Does your screen come back after a reboot?

Do you mean "suspend" or "hibernation" with the word "sleep"?

What kind of version of LinuxMint are you using right now?

Have you recently gotten a new kernel version? This often affects issues with suspend or hibernation. Changing back to an earlier kernel version that caused no problems is often the only and best working solution.

Select menu, then type "system information" , then you will find what type of linux system you are using.

Yes, extensive Details are always needed here, to get useful help. Is your ASUS the "ROG" bad boy with the nVidia GTX 10 GPU? "All" nVidia GPU devices have had proprietary Drivers for many years. The 'soft' GPU drivers in the GNU/Linux world can never get "all" functions correct. [ See Webster's definition for Proprietary ] More importantly for you, is that your GPU will generate HEAT when stressed, which your laptop 'mini' Cooling System may NOT be able to move out ... causing Overheating/Dead PC. Be very careful to monitor your GPU and CPU and HDD temperatures, at all times!... BEFORE making changes.
