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,

    The last thing I can think of is to uninstall HP software and let only drivers.

    Click on start>settings>apps and uninstall all HP software.

    If it doesn't work I will release this question to see if other Experts can have a different tip for you.

    Please release this question to see if other experts can see. Because i don't find any solution to this anywhere

    Hi Chatania,

    Then read update the bios manually from USB Flash drive (outside of windows).

    I think I'm not able to downgrade because of this compatibility 

    it only supports till version 1909 and I'm having version 20H2 right now.

    will you tell me how to rollback using USB, I have the 1909 setup and I cannot rollback using recovery in setting because I've just clean installed this 20H2 version using a USB stick not by win update.

    Hey, I just did the clean install and my bad luck the same issue is still there exactly the same. I don't think that hp software were really causing this problem. I remember before this issue started my laptop was having bios version F.33 and after updating to F.34 this started so now i am sure this is a bios issue so i asked hp and they gave me setup of F.33 and its not letting me downgrade the bios have a look

    I asked hp about it and they told me to go to service center.

    Before that do you have any ideas about this.
