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,

    Can you put do nothing for all 6 . Because I want to know if the issue is from your device or from software.

    Have you tried this

    Just tried it after changing the setting I closed the lid and after leaving for few minutes i opened the lid screen didn't turn on and not responding to any inputs of keyboard and touchpad and mouse.

    Seems like I found another way to get into the same problem.

    Hi,

    Regarding your title "Only while plugged in, the Laptop screen(goes black)" 

    Is it the power adapter the issue or maybe the power management settings?

    I've changed the power adapter and there was no chng. Recently I forced installed Intel MEI ver 9.5 driver through device mgr because the setup stopped me saying the laptop isn't compatible. So the sleep issue which I had, is now resolved(all issues I had before actually are fixed) but one last thing remains i.e., if i leave my laptop idle while plugged and the screen after display time out doesn't wake. So I've changed the power settings to never and turned on screen saver, that was temporary fix for me.

    I think this is because of buggy bios update itself now cause I've tried everything and nothings left, and this started after that update so I'll just wait until nxt update hope it'll fix this one last issue.
