I have been following the steps that you have provided.

1. Unplug the machine

2. Press on power button for five to ten seconds

3. Move jumper to clear bios position and turn on power for 10 seconds.

4. Turn the power back off.

5. Press on power button for five to ten seconds.

6. Put jumper back to original position.

7. Power Back on and turn on.

 

I have repeated the plenty of times but was just wondering it says that it starts up and shuts down again  in seconds. Is this what I should be looking out for to know the bios is reset.

 

Thanks

Hello Cobi,

Thank you very much for the message and I’m very sorry that your HP ENVY 20 TouchSmart All-in-one PC is malfunctioning.

 

The reason that your HP ENVY 20 TouchSmart All-in-one PC is unable to start up is because the CMOS content is corrupted, and this procedure is an attempt to refresh the CMOS content. Maybe you would like to try the very simple approach suggested by Durstee235 in his message dated 08-15-2016 11:59 AM on this thread which I quote here "What he did was unplug the power, and hit the power button on the computer multiple times (like 10-20) and after doing so the screen will work (at least in my case).". If this method does not work for you after numerous time, maybe you would like to try the following approach.

 

As some people find it hard to restore the display, I have listed the procedure on restoring the display step by step in the following. Please follow it very carefully and slowly (do not rush through this procedure).

 

1. Pull the computer power plug from the wall power outlet (please do not pull the power connector from the back of the computer because this causes power surge that stresses the computer and cause problems) and wait for the white power LED indicator on the motherboard to go off, drain the residual charges by pressing the computer power button for 5 seconds and clear the static charge on you.

2. Remove the CMOS battery and put it aside (you will put the CMOS battery back to its holder on the motherboard after you've restored your computer).

3. Clear the CMOS by moving the CLR_CMOS jumper from pin 2-3 position to the 1-2 position.

4. Insert the power plug into the wall power outlet for about 5-10 seconds. You may wish to press the power button on the computer to check that the computer is indeed in CMOS clearing mode. In the CMOS clearing mode, the power button light will light up when pressed but nothing else such as the fan and drives will function.

5. Pull the power plug from the wall power outlet (please do not pull the power connector from the back of the computer because this causes power surge that stresses the computer and cause problems) and wait for the white power LED indicator on the motherboard to go off, drain the residual charges by pressing the computer power button for 5 seconds and clear the static charge on you.

6. Move the CLR_CMOS jumper from pin 1-2 position back to the original 2-3 position.

7. Insert the power plug into the wall power outlet and turn on the computer.

8. The computer will start up and then restart itself automatically within a few minutes after it has completely refreshed the CMOS. (Please give the computer adequate time to refresh the CMOS. For instance, at least 3-5 minutes or more in certain cases. You should observe this process of starting up and restarting. If not, you will have to repeat steps 1 and 3 to 8 again. You may wish to put the computer in CMOS clearing mode and leave it in that mode for a considerable amount of time while you attend to other things if you need a break.)

9. If the first attempt is successful, the screen will come on and display a message after a few seconds whereby you can press F1 to boots the computer. In this case, please proceed to the other procedures mentioned in the e-mail message.

10. If the display is not restored on the first attempt, press and hold the power switch to shut the computer down. Then repeat steps 1 and 3 to 8 carefully and you will eventually get the display to work. If after countless attempts and the display still could not be revived, you may wish to leave the computer unplugged for a couple of days to drain off completely/sufficiently before working on it again; there are several cases whereby the display was successfully revived right on the first attempt thereafter.

 

Thank you very much for your attention and I wish you will get your HP ENVY 20 TouchSmart All-In-One PC to work again soon!

 

Best regards,
Chris

Hi Chris,

 

Thanks very much for the reply. My computer is a hp envy 23 d010ea but I presume it's the same solution as the 20" one.

 

I sorry to be annoying but I was just wondering on the 02-08-2016 08:03 PM that you put up you said that after going through the steps you have given that when you turn back on the computer it should shut down and restart after a few seconds. But on the last one you put up for me it says you have to wait 3 to 5 minutes. I was just wondering do I have to wait 3 to 5 minutes every time I go through the procedure or should I see a sign like a shutdown and restart fairly quickly that I know it is working.

 

Thanks again

Hello Cobi,

 

As mentioned in an earlier message in this thread, HP ENVY 23 AIO PCs have a different pin configuration. Please refer to the following picture of the pin configuration shown on one of the metal plates of the HP ENVY 23 AIO PCs (try to find this metal plate on your HP ENVY 23 AIO PC).

When I did it, the computer started up and then restarted itself automatically within a few seconds after it had completely refreshed the CMOS. However, as many people were having difficulty in reviving their display, I suggested to wait for 3-5 minutes just to be sure that the computer won't automatically restart which meant the computer could not refresh the CMOS content.

 

Since you have the same model as Matt (Durstee235), maybe you would like to try the very simple approach which I quoted in the previous message: "What he did was unplug the power, and hit the power button on the computer multiple times (like 10-20) and after doing so the screen will work (at least in my case).". You may wish to contact him for advice.

May I wish you will get your HP ENVY 23 TouchSmart All-In-One PC to work again soon!

 

Best regards,
Chris

THANK YOU OXIDE (and PhoenixForce)!!!!!  That was an incredibly clear and helpful writeup.

 

I tried messing around with the clear CMOS and the CMOS battery and no luck.  I didn't have an Arduino on hand to follow your directions exactly but I was able to upload a BIOS for my 23-d129 using my Raspberry Pi partially modifying your instructions restoring my Envy 23 to productive use again.

 

My steps:

 

1. I downloaded a NOOBs image to a new SD Card for my Pi.

 

2. Downloaded flashrom to my Pi – First time through I had a few dependency issues until I found this install command:

 

sudo apt-get install build-essential pciutils usbutils libpci-dev libusb-dev libftdi1 libftdi-dev zlib1g-dev subversion

sudo svn co svn://flashrom.org/flashrom/trunk /flashrom

cd /flashrom

sudo make

sudo make install

 

3. I copied my new ROM image (downloaded from the HP website – after installing the .exe installer, there was a new folder on the root of my C: that had the .ROM file.) to the /flashrom folder.

 

4. I wired up the Pi following your instructions and some other instructions on the web to make sure I was connecting everything to the proper pins on my 40 pin Pi connector. I had a breadboard and some header wires / pins that I was able to use from a Sunfounder kit I had bought before. Using the pin names from your diagram:

 

SPI_CS# -> Pin 24 (GPI08)

SPI_MOSI -> Pin 19 (GPIO10)

SPI_MISO -> Pin 21 (GPIO09)

SPI_CLK -> Pin 23 (GPIO11)

3V -> Pin 17 (3V3)

Gnd -> Pin 39 (GND)

 

5. Before flashrom would work, I needed to modify the /boot/config.txt file to uncomment dtparam=spi=on and then restart the Pi.

 

6. I checked to see if the connection worked first by running the following which created a backup the current ROM:

flashrom -p linux_spi:dev=/dev/spidev0.0 -r old.ROM

 

That worked fine on the first try. So I then wrote the new rom:

 

sudo flashrom -w /flashrom/NEWROM.rom -V -p linux_spi:dev=/dev/spidev0.0

 

(where NEWROM.rom is the name of the new ROM).

 

That also worked perfectly and then I was able to boot up the machine and update the BIOS using HP’s EXE.  Only issue is the new BIOS version seems to crash at POST when my Kinect is plugged into the computer, but that seems to be a known bug.  Previous BIOS version didn't do that.

 

THANKS AGAIN!!!

Thanks to Oxide's detailed post from August 5. 

 

I had no success switching the CMOS jumpers so as last resort went for the BIOS flash.  I'm not a computer expert so this was new territory for me but there was really no downside as all I had was an expensive brick.

 

I bought an Arduio UNO clone that cost about £10 and followed the instructions in Oxide's post.  I ran into a bit of trouble using Ubuntu in VirtualBox as the Aduino didn't get recognised when it came to writing the flash program.  I solved this by reinstalling Ubuntu alongside my OS rather than through VirtualBox and installed the Linux version of  Arduino IDE software into Ubunto to check the connection.  I googled the error and found a YouTube video explaining how to fix this and the rest of the process was straightforward.  If you have that same problem I found the YouTube fix was only temporary so don't unplug the Arduino from the USB until you are finished writing the flash.

 

The computer rebooted and all seems basically ok.  I had one small problem with a driver (jnprns.sys) that caused the computer to crash as soon as I connected to the internet either by wireless or ethernet.  I had to reboot in safe mode to delete this driver (after uninstalling all Juniper/Pulse apps/files) as it seemed to be used by something in the start-up. After that everything was fine.

 

However what I wanted to do was go back to a prior verison of Windows or even the factory install so as to prevent the black screen recurring. I find that when I use the recovery options (doesnt matter which option I use) the process starts but I get a WDF-violation error and the system reboots with no changes made.  It still reboots and opens properly so I'm not unduly worried just now but trying to get to the bottom of that.  But at any rate at least I have a working PC back.

 

So, thanks again to relevant posters.  As I said. I''m a novice with computers so I'd recommend trying to flash the BIOS if you are still having problems.

Hi guys I'm not sure if this post is dead or not but over the last few weeks I had this problem with my envy 20 and I tried resetting the cmos with all the different variations you guys did like waiting longer while have the pins in 1-2 or 2-4 and even replacing the battery early when changing the pins to 2-3 or 4-6 and all the results I got was the pc either not resetting, the pc resetting after a couple of seconds then not resetting at all, me turning it off and then it resets the second time and that's it or it'll just reset in a loop but I have no luck with the display turning on any help is appreciated. And by the way I left the pc unplug for hours and followed all the power disconnection techniques

As I understand your computer gets nothing but a black screen during initial boot,

And you are unable to reset it as none of the keys responds
(Please correct me If I'm wrong)
 

Have you attempted any other steps of your own to solve the issue apart from the ones, you have mentioned?
 

please attempt the below steps:
 

Perform a hard reset
 

Attempt a BIOS recovery
 

If there's no display, use an alternate monitor
 

Run the System Diagnostics tests
 

For more steps, click here


Let me know if those steps worked for you. 
If they did, that’s awesome!

I used an elegoo clone for the Arduino Uno R3 and after 3 or 4 tries the write finally worked (kept hanging during the reads). Booted right up with the Screen again working. The instructions provided by OXiDE were excellent - thanks much.
