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

Anonymous

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,

I think you found the same issue because the dump files never changed. They are the same file as I checked the timestamp

And I tried uninstalling that Elan app from settings>apps and also from device mgr but after reboot they get installed again. The thing is I need that touch pad app because without that I cannot use any gesture on touch-pad as I use it most of the times.

I really don't think that issue lies in these drivers but in Intel MEI drivers because I've seen that blk screen only happens on battery but after checking the option "Allow computer to turn of this device" in pwr mgmt tab of that driver the issue occurs even while on battery power, as for now I've left it unchecked that's why its not happening on battery.

And I saw this error in Event viewer sys tab is this OK or this needs attention?

MEIx64:-Intel(R) Management Engine Interface driver has failed to perform handshake with the Firmware.

Hi

It is the same file (ETD.sys) that causes the BSOD. Why don't you just completely uninstall it reboot your laptop and see how your laptop reacts without that apps (Elan touchpad) then we will know if it is not the responsible of your BSOD.

Ok I found one file that causes a BSOD, it called ETD.sys from your mini dump file.

To read more about ETD.sys please follow the link don't download anything there, I send to you to just get an information about the file https://www.file.net/process/etd.sys.html

KMODE_EXCEPTION_NOT_HANDLED ETD.sys+4e9d6 (relate to mouse pad) (is possible your black screen is caused by this ETD.sys) Get an external mouse ready in case your mouse pad refuses to work after the modification we are going to do. Here is what you are going to do.

open command prompt as admin

cd\ (hit enter key on your keyboard)

C:>

C:>cd windows\system32\drivers (hit enter key)

C:\Windows\System32\drivers> ren etd.sys etd.sys.old (hit enter key) (ren command is to Renames a file or files)

Then reboot your laptop

Work with your computer as you did and see if the blank screen is still there, we close the laptop lid when we use an external monitor connected to the laptop ports (vga, hdmi,dvi). You can still close it to see if it freezes. Leave a feedback

Hey, I tried this after I reinstalled factory version drivers of Elan touchpad as I told you before that I was using unofficial drivers which u said was the reason for BSOD. but now after reinstalling official HP drivers and running those commands it showed the ETD.sys file is not present(I think that file was of unofficial drivers). So I tried closing the Lid again and the BlackSOD happened again I had to hard reboot my laptop. So I'm sharing the dump files again to see if you can get any other error msgs.

And this is even happening after connecting the HDMI cable. One thing I observed that when I closed the lid jus enough for the screen to turn off and while the HDMI cable connected I tried to move the mouse with touchpad and tapping keys and they didn't respond after closing the lid but when I opened the lid they worked only External mouse worked at that time.

>>Before You asked me which port did I use for External monitor it is HDMI port.

Here is a workaround leave a feedback

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 dump files. I know that the files are of today and I am facing the issue its not fixed yet but what I am trying to say is ETD.sys is showing because I don't have official HP provided ELAN touchpad driver as ETD is ELAN touch driver and I've changed the driver to another ELAN unofficial driver which enabled Windows precision touchpad drivers(I gave above link from where I downlded). I still have the Unofficial ELAN drivers and this BlkSOD issue is been since I purchased this laptop 2 yrs ago, even when I had the official ELAN drivers from HP. I've tried restoring the official ELAN drivers and no change.

I'll install official ELAN drivers and then give you the dump files again may be then the main reason will show up.
