did you run these commands in terminal:

sudo pmset -a standby 0
sudo pmset -a autopoweroff 0
sudo pmset -a hibernatemode 0
sudo rm /var/vm/sleepimage
sudo mkdir /var/vm/sleepimage

Hi Yes but it doesn't help. if i close the lid or put system to sleep there is no way to wake it up. I have to Hard reset the laptop from the start button.

Not sure about your XPS 15 but with the latest one (9500 year 2020), Dell's S3 sleep implementation in the BIOS is broken. You wake up to a blankscreen or dell logo if you have sign of life enabled.

You can confirm this by enabling S3 with Win10 as well (by default S3 is not used on Windows).

can you guide how to do so

If you're using Win10 2004, it's a lot harder (blame Microsoft).
On pre-2004, refer to this https://www.tenforums.com/tutorials...ans-windows-10-a-post1502109.html#post1502109

Have you resolved the issue? I have the same laptop and experience the same issue with screen not waking up from sleep.
