I think the title covers it all. I have KDE Neon dualboot with Windows 10. 9 out of 10 times, if it gets to sleep mode it does not wake up. I need to press the power button to power on the laptop again. I am at my wits end about this issue.
Edit:
Expected behavior: When the laptop goes to sleep/suspend mode automatically or manually by closing the lid, I will be able to wake it up and continue working.
