Bios issue after windows update

[VampHalen]

Just run latest windows update and now stuck in a bios update loop. Please help

@VampHalen -- after 3 or 4 consecutive "failures" to load Windows 10, does your computer open to a "Recovery Console", where you can try various trouble-shooting options, including a "time-warp" back to a date/time when Windows was working.

I had the exact same problem with my 15-db0018ca laptop. But I went through the Windows update to never come back. Now the screen is always blank when I turn on the laptop and the fans spins to top speed.

I had the very latest W10 update, which was "Windows 10 Version 20H2 (64-bit)". Thanks Microsoft for breaking my computer, so good job. Thank you. Well done.

By the way, I tried all the available solutions from the Virtual Agent, and nothing worked. I tried hard reboot:

• Removing all external devices and components.
• Power reset or hard restart.
• Connecting external monitor.
• Using the internal HP BIOS Restore tool.
• Using a USB drive HP BIOS Restore tool.
• Resetting the memory modules.
• Removing the battery.

Nothing worked.

Please, HP support, do something! You'll get hundreds of clients affected by this Windows update in the coming years.

@carloswm85 -- Now the screen is always blank when I turn on the laptop and the fans spins to top speed.

Did you try:

1. power-off the laptop
2. disconnect the AC power-cord
3. remove the battery
4. hold-down the on/off button for a few seconds, to drain any residual electricity
5. reconnect the battery & the power-cord
6. power-on

Anything?

When you power-on a computer, the motherboard first runs the POST (Power On Self Test).

One step is to temporarily run the fan at 100% speed/noise, and then to sense the temperature of the motherboard & processor, and then to tell the fan to slow-down (and get quiet).  So, it seems that this step within the POST is not completing properly.

If the computer was purchased less than 12 months ago, contact HP Support, to open a claim against the Warranty, to get HP to repair/replace it, at HP's expense.

Otherwise, your only hope is to take your computer to a good technician, to try to trouble-shoot.

You may remove the disk-drive, to extract your Personal Files.

I already tried that, but I'll do it again following the exact steps you've detailed (I'll update this post when I do so, so please check my reply again next week).

Thanks for the information you've shared about the motherboard behavior. And your advises.

My computer is not inside the warranty period. Nevertheless, HP should do something. It is absurd that a "supposedly secure" update from Microsoft do this. Someone has to take responsibility of this problem suffered by customers provoked by big corps.

@carloswm85 --  I went through the Windows Update to never come back. 

An experiment: remove the disk-drive from your computer, and connect it to a different computer, as the "primary" bootable device. Disconnect any Ethernet cable from the different computer, for the purposes of this test. Power-on that computer, and boot from your disk-drive. Does Windows (20H1) successfully start, to try to prove that the update was successfully completed on your disk-drive?

[VampHalen]

Have tried getting in contact with support since the time of posting, absolutely impossible to get in contact with them. Have tried calling & messenger/WhatsApp support with no joy. 20 odd days left of warranty and I'm sure I'll hear something back soon enough once it falls out of warranty. Can't even download bios image to attempt to flash/upgrade/roll back as their website has no images available. 

[VampHalen]

Nothing at all, just keeps looping BIOS UPDATE, WRITING NEW BIOS IMAGE, VERIFYING NEW BIOS IMAGE, CLEARING PENDING IMAGE, PREPARING AUTOMATIC REPAIR, APPLYING UPDATE THEN BACK TO START

I haven't had the time to try the other solutions proposed in this post. I will.

In the meantime I was doing some research in this problem, and I want to share this video with you guys that may enlighten some other visitors to this post.

How Risky is Updating Your BIOS? ( + Corruption Demonstration) 

In the demonstration he uses HP14, and the HP recovery tool and some other solution. But none of them work.

I'd like to see HP taking some responsibility on this. Really, if things like this happen to your perfectly-working-and-healthy products, you're just losing customers just because. Not to say that I still need to contact Microsoft because the update they sent was the one that caused the problem in the first place (assuming I didn't make any mistake while making the update, which as far as I'm concern, I didn't).

I'll try to implement the proposed solutions in the following weeks, and keep you update.

Okay, sadly this solution didn't work: https://h30434.www3.hp.com/t5/Notebook-Operating-System-and-Recovery/Bios-issue-after-windows-update...

The fan just kept running to 100% speed and the screen stayed black the whole time.

I'll go on trying the other proposed alternate solutions. I'll keep posting.
