Dell XPS 13 (9343) having sleep issues

I have a Dell XPS 13, early 2015 model, which has been having issues with going to sleep or sometimes waking up from sleep.



The issue is encountered when I will close the lid to put the computer but instead it will keep ON and drain the battery. The computer will need to be hard rebooted by holding down the power key after the battery has been charged. All of the data that was open or unsaved on the computer before will be lost.



Sometimes the laptop would go to sleep fine but when the lid is opened the screen's backlight will come on but nothing will be displayed on the screen. The computer won't respond to any commands beside holding down the power key to hard reboot. Again, any data that was open or unsaved on the computer will be lost.



I have tried making a habit of putting the computer to sleep by pressing the power button before shutting the lid but it will still somehow end up waking itself and draining the battery or it won't respond when the lid is opened requiring a hard reboot and therefore I lose all my open files.

Every time the issue happens, I have tried to run "powercfg -lastwake" but it says "wake count - 0"

I am running Windows 10 with all the drivers and BIOS updated to the latest version.

This issue also occurred in Windows 8 before I upgraded so I am wondering if it is hardware issue?

Is there anything else I can try to fix this?

Is shutting down the laptop instead of putting it to sleep only other solution?
