HP ENVY H8- 1534
Microsoft Windows 10 (64-bit)

Changed bios to secure boot.  Computer did restart without any issue.  The next day, on pressing the start button. Nothing. No beeps, sounds, video.  Nothing.  In order to access bios, I needed to reinstall original video card. Still,nothing.   I reset CMOS,( My jumper pins are not the same as the HP site says)  no change, changed the battery, no change, brand new power supply, still nothing.  I am looking at the BIOS_REC jumpers but do not have a guide before I try to move jumpers.  Any help will be greatly appreciated.

There seems more to the problem then just the bios.  Your motherboard was made by gigabyte and has an SPI programming header

Specific instructions that might be useful are here

Various SPI programming tools

 

Tap ESC key after power on and see if the HP diagnostics can run.  If the ESC key is recognized you should be able to get into the bios.  Try another video board if more than one available.

Hello, and thank you!

 I got as far as swapping the video card, clearing the CMOS, removing the CMOS battery. 

removing all components, unplugging the power supply, removing the CMOS battery, holding down the power button for three minutes-120-180 seconds, replacing the CMOS battery, and power supply then try restarting- and still nothing.

 The escape keep option wouldn't work as the Keyboard and mouse are USB, I also used a Bluetooth keyboard and mouse) but nothing received any power.

 Neither one is being recognized. -No power to them as one keyboard will normally light up on Power On. But nothing now. The DVD drive has power to open and close, but the computer is not seeing the data on the disk. 

I have changed power supplies, moved the BIOS_REC jumper to each set of posts hoping I would somehow stumble onto thesolution. Still nothing.

 I Prayed, swore, and cursed it too, but none of that helped either.

 That is where I stopped.

I am not certain I understand the

 SPI programming header exactly. is that Flashing the Bios?

By what I have seen on the threads  and I may be mistaken.

 

   I assume- I am to take some wire, and connect it to the empty jumers in the combinations from instructions link- Hibiscusguy(?)

 

Here is the pin out for the Rom Recovery Header to the LPT port:

Like I said I am only guessing-  and I have not attempted this at all...yet, until I have abetter understanding

 

Connect Pin 1 to Pin 7 with a wire??

 

Then follow suit with the rest of this?

 

pin 1 to 7 lpt                                 

pin 2 -- Not used

pin 3 -- Not used

pin 4 -- 9 lpt

pin 5 -- 3.3v (MUST USE 5V TO FLASH, SEE BELOW!!)

pin 6 to 10 lpt

pin 7 to 18 lpt

pin 8 to 8 lpt

I am going to pull the motherboard tonight and see if there is a short on the bottom- I am going from experience on that. I had an ASUS MB before this PC that shorted out under one of the MEmeory Stick slots. But that is just me guesing.

 

Thank you for what you have already mentioned. I appreciate any and all info. If you have anything else I might try, or maybe, if you could, explain the header thing to me alittle slower (humor) so that I know what you mean. othjerwise, again. Thank you.

The SPI header is used by the manufacturer to flash the bios  in the event the bios needs to be updated before installing in a system.  

 

A properly equipped and trained tech support could do this. They might charge more than a replacement motherboard.

 

Probably time to move on to a windows 11 capable system unless there is a guru in your neighborhood that can help.
