Bios update loop

[GB991]

Hi all,

I recently had a faulty cooling fan replaced on my laptop and all appeared well but on each boot up, there was a warning that the fan had a fault. I checked if there was a bios update and it seemed so, so I downloaded this and set the system to update.

Now, I'm stuck with the bios update loop several others have described in the community. The bios updates, then cannot verify. It tries twice, then restarts and repeats; update, no verification (x2), restart. I can't interrupt the process with f10 or windows key V or B.

Has anyone actually resolved this issue? The laptop is a Pavilion 15-cwxxxxxx. It's barely 18 months old and hasn't really had much use.

Thanks in advance.

Hello,

Thanks for replying. I'd already reported that this doesn't work in my initial enquiry. I tried it again anyway and am still getting the same issue that upon startup, the laptop opens the HP BIOS Update screen, rewrites the BIOS then cannot verify it. It then reports the error and offers to restart. Upon restarting, it goes back to the start of this process again ad nauseam. 

As I said too in my initial post, the heat from the charger being plugged in and charging the battery is slightly worrying now that the replacement fan is not running.

I appreciate this might be a complete reset and loss of personal data on this machine, but I'd be grateful for any alternative suggestions you have, or guidance on how to reset the machine if that is sadly the only option.

Thanks,

Gordon

Hi again,

So - can I confirm that you think there is nothing further I can try and I should start taking it to pieces in order to salvage my personal data? If so, can you suggest the best method for then reinstalling the necessary BIOS and  OS?

Does feel a bit extreme for what was a fan failure here.

Hello @GB991 

You made a mistake. Instead of checking the fan problem (disassembling the notebook), you did a BIOS update, which went wrong. Now you have 2 problems.

Kind regards

Hi,

Odd tone to take for someone 'trying' to help.

Also, you're wrong. As I said in the first post, the fan was replaced, which, as you'll well know, involved taking the notebook apart. The new fan worked. The laptop worked; the only issue was the BIOS now reported that the fan wasn't working even though it was. Therefore I looked at the guidance on the HP site for updating the BIOS, followed that and here we are.

Hello @GB991 

Yes, you have replaced the fan. But I don't know exactly what you did and what could have gone wrong. It is strange that the BIOS suddenly does not recognize the fan. We are now trying to solve the problems:

(1) Download BIOS file ( with another computer )

HP Notebook System BIOS Update (AMD Processors)

F.48 Rev.A

Download

(2) --->>>> BIOS Recovery Reinstall with USB

(3) Please report your results

Hi,

Apologies for the delayed response; I tried this and it didn't work; still looping so I handed it back to the technical repair agent who installed the fan and they can't get out of the loop either.

I am out of warranty, but now appear to have a machine that has been 'bricked' by solely following HP's guidance on installing that April 2022 BIOS update. Before I started this process, the machine was working absolutely fine, but just had the fan recognition error on each boot up process which wasn't a huge inconvenience and was certainly preferable to what is now an expensive coaster it appears.

I'd be really grateful if there are any other suggestions on what to do here and apologies for sounding ungrateful; but this shouldn't have been difficult and shouldn't have rendered a machine that is less than 2 year old inoperable.

Thanks again for reading,

Gordon

Hello @GB991 

That's the way it is with electrical technology, either it works or it doesn't...

This is the last solution

You could order a pre-programmed BIOS chip on the Internet and have it soldered in.

Good luck
