After BIOS update no display

[Unfriendlybios]

My PC is 25 months old A Pavilion TP01-1227c running Windows 11. All updates and security program always updated. A windows update included an HP BIOS update, that was odd because the HP updates normally show under optional but it was there so I clicked to install. After an hour the screen was still black like it had shut down. After power cycle and start no change. After trying a new monitor and checking the web and trying the suggested methods with no success, I called HP support. I explained it started with the last BIOS update. My PC was out of warranty so I purchased the service and was connected to a tech, After I explained again the tech said they cannot help with a BIOS problem a second tech said to try the power cycle and hard rest options so desperately I tried again and no change. By the end of the day, I purchased a new PC. It took a few days to get that set up so I ignored the old PC for a while. I have exhausted all my options to get all the files I need but still some things are missing. Now I would like to access the old PC but so far nothing on the net has helped. I get it HP, Microsoft, or Intel want no part of the blame but why am I left with a brick and no help because I used windows update?

This statement " I have exhausted all my options to get all the files I need but still some things are missing."

Assuming that you mean there are things or data that are still needed from the old PC?

Since it is not explained what these remaining things might be, you can remove the hard drive from the old PC and connect it to the new PC either directing by using a SATA port and power or using a USB to SATA adapter to provide access to the old drive and search for the data still  needed.

If some of those things are programs, then that is problematic.

Thanks for your input, sorry I was unclear, "Now I would like to access the old PC" I should have underlined that.  So please in this thread  reply only about trying to get this PC up. If I go in a different path I will look under other categories.

Hi, @Unfriendlybios 

Before you take the PC apart, try recovering the BIOS using this method if you have not done so already.

Plug a USB flash drive in another PC.

Download and run the previous BIOS update for your PC from the link below on another PC.

Driver - HP Pavilion Desktop - TP01-1227c | HP® Customer Support

I just ran the above file on my Dell Optiplex 7050 MT desktop.

If you didn't buy the same model PC, when you run it, you should only get an option to create a BIOS recovery drive.

The program will ask you to select the flash drive you want to create the recovery drive on.

It will format the drive and create the recovery drive.

When the recovery drive has been completed, these are the simple instructions to follow...and hopefully this will recover your dead PC.

1. Power off the device to be recovered.

2. Insert the USB flash drive into a USB port.

3. Power on the device.

4. The device may reboot up to 3 times with indicator lights on the keyboard flashing, or the screen appearing blank for short time.

Paul, Thanks again it looks like you put quite a bit of effort into your response but I want other people that see this thread to know this; My situation is the monitor (checked on a different PC and the broken PC checked with a new monitor) does not display NO DISPLAY the monitor power button is on yellow like you turned off the PC . The PC was not set to boot from flash drive. So any of these comments do not apply to my HP1227c with this problem. You cannot boot or recover without access to a screen and make selections. Only if your PC was set to boot from a flash drive this may help you. If you have screen you can use boot methods from the PC. HP and Microsoft say this problem was not their fault or responsibility. If your PC is under a warrant you will get support but it is odd that all the related posts are only PC's without additional coverage?

You're very welcome.

Sorry, that didn't work for you.

But one thing you should note.

The PC does not have to be set to boot from the USB flash drive.

The PC will automatically detect the flash drive as I indicated in the instructions.

Most PC's are not set to boot from the USB flash drive.

The Windows boot manager decides what device to boot from.

In August - September, a BIOS update wrecked a good deal of HP all in one PC's and all the folks needed to do was to make the bootable USB recovery drive, plug it into their PC when it was turned off.  Turn the PC on, and the PC automatically detected the flash drive and recovered.

Some examples:

Here's one very similar to your situation.

Solved: Re: No display day after BIOS update - HP Support Community - 8892925

And there are many more but most of them are related to those all in one's with the MonkD motherboard.

I am concerned with how unreliable the BIOS updates are in HP consumer desktop PC's.

I would be very upset if that happened to me on a perfectly good and expensive PC.

I only use HP and Dell business PC's and never had any problems with the BIOS updates from the support sites or those new ones pushed on us from Windows update.

I think you know a lot about PC's so I won't disagree with your info. In my life I have owned less than a dozen PC's and any at work were governed by IT. In my case the first thing I tried was the HP boot flash drive. Then after a number of other attempts including HP paid support, a multiple list from HP articles, They all include steps saying to use power button to reset, force to start from flash drive, remove or disconnect various devices external and inside the PC. Some of the HP help articles have changed or display no longer  available just since 2 weeks ago. One thing for sure this bios update for some disables display and or USB ports. It would seem that the traces of the problem get redirected so as to not point to any HP or Microsoft acknowledgement of the problem and inaccurate fixes cannot be their fault. The caveat being if you tried this step or that it's not our fault it is yours. Simply connecting the hard drive to the new PC (I was forced to by) would end the saga but in a timely manner windows 11 has to many problems not recognizing external hard drive. If you are smart like Paul, you probably keep warranty extended or do not install BIOS updates just because the are in windows updates. It was even rumored tat HP would have someone post under a problem to claim this is fixed or resolved so people with the same problem get off tracked and accept it was their fault and unfixable. So readers when you see SOLVED in an HP post,  that only means do not add to the existing post it would look bad if a million people had the same problem from the same reason.

Hi @Unfriendlybios 

If that last post is aimed at me, then I am way below @Paul_Tikkanen  as far as knowledge on these matters.

I was just trying to help.  Paul stepped in with much better information and I am glad he did.

You did not explain what was missing in being able to get data from the old PC, so I offered a way that the common user could use.

[Unfriendlybios]

Please only post if you have any useful information. The simple fact is an HP BIOS bricked my PC and many others shortly after they fell out of warranty coverage and offer no help to recover.  I am posting to get more people that were taken advantage to see what is going on. Paul  did offer many practical steps to try, unfortunately I had tried those and more before I started this thread. After I paid for HP support to help with this issue they said they could not do anything to help with BIOS update problems unless I had existing full warranty coverage. If that indicates any level of PC knowledge that has no answer. My original statement was descriptive and accurate but solved to this in anyway is not true and helping HP to burry the problem they caused.
