Inspiron 17-7373, LCD won't wake up
Inspiron 7373 2-in-1
I have an Inspiron i7-7373 running Windows 10
I am Facing Sleep mode issue that
If the display turns off due to the normal power saving setting, it won't turn back on. I have to hold the power button down to force the machine to turn off, then reboot it.
This doesn't happen if I initiate a sleep or hibernate action (manually, or by closing the lid). It only happens when the timer to turn off the display is triggered. I've tried resetting the power plan to the default settings, but it made no difference. I'm running the latest BIOS/UEFI version, and I'm running the latest graphics drivers from Intel for the i7-8550U with (Intel UHD Graphics 620).
This started a couple of months ago. The only thing I've been able to do is set the display to never turn off. When the problem occurs, the keyboard LED lights up, but i can't get the display to come back on, and I can't get the system to respond to anything else. (I've tried running commands with the display off, such as windows +r, shutdown -r -t 0, enter for a restart. I've tried closing the lid then reopening it to try to trigger sleep mode. Etc.)
Is this a known issue? Is there an actual solution?
