Only while plugged in, the Laptop screen(goes black) doesn't respond after idle screen timeout.

Hello there,

I've been facing this issue since 2 years now, seems like a simple problem but mine is really weird, I didn't get any query regarding my issue hence I decided to post it myself. Please read my post completely and please help me resolve this issue.

When I leave the laptop (HP Pavilion 15-cc1xx, win 10 64 bit, Intel core i5-8250U) idle, the screen turns off to save power & doesn't respond to any inputs even external connected USB mouse light turns off (I saw that when this happens the HDD LED turns off I suppose the HDD is not waking). After screen turn off it is suppose to go to sleep but the power LED and fans are continuously on until I hard reboot using power button.

Here is the weird part--- This only happens if my laptop is plugged in and doesn't occur while on battery. The power options screen is shared below

I've tried doing almost all troubleshooting like updating drivers, BIOS, and sfc scan and also reset but all in vain.

Sometimes, this also happens when I put it to sleep, but this sleep issue occurs very rarely cannot predict when it happens I've to hold my breath when I press sleep and wait until the power LED starts blinking for confirmation or else I've to again hard reboot only to loose unsaved data. Although this sleep issue happens very very rarely.

I think the issue is only with HDD since the HDD LED stops blinking when this happens ***.***When it is blinking then I'm sure that the screen will turn on as I've seen it for myself many times.

Here is the picture of power and HDD LED I was talking about,

    There are no minidump files there you told to delete and after that they did not get created.

    Are you using HP docking station? For the external monitor, Have you done this below 

    step1: Change the hdmi cord

    1. As short as possible (6 ft should be ok).
    2. Properly shielded and high-quality
    3. Heavy gauge wires inside (like 24 or lower)
    4. Straight-thru cables (no Redmere or other non-sense build-into them)

    Regarding the elan drivers, I did It, exactly as the site said from step 4, but the problem still persists. 

    After that failed, one more thing I tried to do in the same way is uninstalled intel MEI but it installs again even though the auto install option "no" is ticked. I still strongly believe that it is Intel MEI issue even Robin(independent advisor here) in previous replies told that. What do you have to say about it?
