HP Envy 23 AIO: No Beep, Screen Blank, No USB

Certainly can. Open the executable on another computer. Run it, wait for it to fail. Then go to c:\Swsetup\spXXXXX (forget the exact Softpaq number). The file you want will have an extension of .rom

You can rename it whatever you like.

HP Envy 23 AIO: No Beep, Screen Blank, No USB

Anyone have an issue where after the recovery, the BIOS settings keep resetting to default at every boot? I suspect it has to do with the serial numbers and other data not present. I tried the usual programming tools (nbdmifit etc) to no avail. I know these tools usually only support business grade notebooks but I gave it a go anyway. No dice.

Sure it's not a dead cmos battery? I haven't had any issues with the bios resetting.

New battery, voltage checks out too.  One solder joint in the back probably came loose from messing with it so much.  I'm done with it though.  Runs well otherwise.  I managed to program all the SKUs and what not with SMBCFG - great tool.  

 

One other thing to note, at least for me.  The Intel ME disappeared completely after this process.  Not the end of the world, but FYI.

MUCH love! :D

Succesfully ressurrected a Pavilion 23 AIO 23-b006es. All is well again

 

Was getting a bit nervous when writing the new rom as it took 37 minutes. But no need to worry.

 

Big ups!

Great News. Did you write bios through Arudino or Raspberry PI. The Arudino with VM hasn't worked for me - so I was gonna by a Raspberry PI

IT WORKED!!

 

 

  • I ended up buying a Raspberry Pi  (which is a nice new gadget to have) and used that to do the reading and writing of the flash chip.  I didn't have the jumper cables that would work with the Pi - so I ended up using both the Raspberry Pi and Arudino.     I think my problems were with security around the Virtual Box of Ubuntu - so having Ubunto on the Pi directly to the Arudino seemed to help. 

 

  • Even after I "wrote the new" BIOS and was succesful - i was so stressed that my machine didn't come on.  I was able to throw it away for good -- and then decided to re-insert the CMOS battery and move the Recovery Pin (I had lost track which 2 pins it was supposed to cover).    It ended up that I had the CMOS battery backwards or the recvoery Pin in wrong place.   Possibly both were issues - but the machine did start back up!

 

Many Thanks to PhoneixForce and Oxide for all of your help!!

 

I wrote up some details that I used on my site at: https://marcusstouffer.com/2016/11/25/raspberry-pi-and-arduino-uno-r3-to-manually-flash-hp-envy-bios...

Thath's great.  I bet this recovery works on any HP desktop that has the recovery port too.  Hopefully they will continue to build them that way.

Hi. Which Raspberry Pi did you get? There seems to be different kinds. I am trying to flash the BIOS using a cheap Arduino UNO R3 compatible board but it gets stuck at reading the flash contents and just sits there.

 

Thanks

This one here.

I believe they all have the same pinouts though.
