HP Envy Curved All In One 34-b1xx

HP Recommended
HP Envy Curved All In One 34-b1xx
Microsoft Windows 10 (64-bit)

My HP Envy Curved All In One 34-b1xx is a great computer (love the size of the monitor) and only a year old.  Unfortunately, the screen occasionally blacks out, although the computer is still running.  In fact, I can keep typing and when the screen comes back on, the words I typed are there.  This started happening many months ago but wasn't very often so I ignored it (wrong).  It occasionally said "Check HDMI-In Cable", but I didn't have any cables plugged in aside from the power cord and the wired network.  Now the screen goes off and on quite a bit, every few seconds, after I've been using it for an hour, or even less.  I have been able to shut down and restart.  I worry the window of usability is shrinking so want to fix soon.  Thanks for the help!

@CornHusky
Thank you for posting on the HP Support Community.

 

Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details:

  • Did this happen after a recent window or software update?
  • Have you made any hardware/software changes?
  • Did you make any changes to the settings of your PC prior to the issue?

While you respond to that, let's try these steps: 

Hard Reset: Follow steps from the link: https://hp.care/2GnkMa8. (do not skip any troubleshooting steps even if you feel steps are repeating)

BIOS default: 

  1. Turn off the computer and wait five seconds.
  2. Press the Power button to start the computer and repeatedly press the F10 key to enter the BIOS setup menu.
  3. On the BIOS Setup screen, press F9 to select and load the BIOS Setup Default settings.
  4. Press F10 to Save and Exit.
  5. Use the arrow keys to select Yes, then press Enter when asked Exit Saving Changes?
  6. Follow the prompts to restart your computer. Once it's done please follow the next steps.

Perform Windows Update and HP Support Assistant: (do not skip any troubleshooting steps if you feel steps are repeating) 

To check for updates now, select the Start button, and then go to Settings  > Update & security  > Windows Update, and select Check for updates.

Install updates from HP Support Assistant: Go to Download HP Support Assistant to install the tool.

  1. To open the HP Support Assistant, double-click the HP Support Assistant icon https://support.hp.com/doc-images/932/c05040382.jpg.
  2. Click My devices in the top menu, and then click Updates in the My PC or My notebook pane.
  3. Click Check for updates and messages to scan for new updates.
  4. Review the list of updates. Updates with a yellow information icon are recommended. Updates with a blue information icon are optional.
  5. Click the update name for a description, version number, and file size.
  6. Select the box next to any updates you want to install, and then click Download and install.

And, also run BIOS Update: Follow steps from the link: https://support.hp.com/in-en/document/c00042629

 

Hope this helps! Keep me posted for further assistance.

Thanks for your response.  I will give your steps a try.  To answer your questions:

  • Did this happen after a recent window or software update? No, this has been a recurring problem that keeps getting worse.
  • Have you made any hardware/software changes? Not lately
  • Did you make any changes to the settings of your PC prior to the issue?  No.

I will keep you posted.  Thank you again for your help!

Hi again.  After reviewing the link at https://hp.care/2GnkMa8, I wanted to make sure the hard reset applies to my situation b/c I do not have an HP Envy laptop, but an all in one, and also, my screen goes blank then comes back on intermittently, rather than stays blank.  Just wanting to make sure before I get started.  Thank you again for your help!

Good morning!  I was able to limp along with my computer but finally followed all your recommended steps a little over a week ago.  I thought the problem was solved bc there were quite a few updates to do and things seemed to be working fine until yesterday.  My screen started blacking our intermittently.  The computer still worked as I could continue to type and when the screen came back, the words were there.  Unfortunately, the screen blacked out every few seconds making it impossible to use.  I tried shutting down a few times and the problem would reoccur within an hour or less.  No failure message or other pop ups this time like before with “Check HDMI-In Cable.”  Note, there is no such cable plugged into my computer: only the power cord.

 

Thank you for your assistance.  I really appreciate it and hope you can help me get things fixed!

Thank you for posting back. 

 

This sounds like hardware related issue with the computer. 
I would request you to reach out to our Support and our Support Engineers should be able to check the available service options in order to diagnose the computer physically. HP Support can be reached by clicking on the following link: www.hp.com/contacthp/

Hi.  Thank you for all your help.  Unfortunately, I have not been able to receive help through the HP Support link you gave me: www.hp.com/contacthp/.  After clicking on this, it determined my 1 yr warranty expired Nov 1, 2019  (the problem started before then, but I didn't follow up soon enough).  It led me to finding my nearest HP Service Center, which is 40 miles away.  I've called that third party several times and left messages with no response.  The next closest HP service center is over 80 miles away.  It would be great if I could speak with an HP Support Engineer to get help with the hardware issues I'm having.  My computer works intermittently, even when the screen goes black, but it doesn't always come back on.  I can tell it's on it's last legs.

 

You've been so helpful throughout this process.  I appreciate any further help.  Thank you!
