Request for BIOS F.24 Rev.A (sp77968.exe) for HP 15‑ac147ns + Windows 11 advice

[NXR2]

Hello,

I own an HP Notebook 15‑ac147ns currently running BIOS version F.20. I understand that the last official BIOS for this model was F.24 Rev.A (SoftPaq sp77968.exe), but I can no longer find it on HP’s support website or FTP server.

Could someone from HP or the community please provide me with a safe, original download link for this BIOS update, or share the file if you still have it? I want to make sure I’m using the correct version for my exact model.

Also, I would like to know if you recommend upgrading this laptop to Windows 11. I’m aware that the Intel Core i3‑5005U processor is not officially supported by Microsoft for Windows 11, but I’d like to hear your opinion on stability and performance if installed with the necessary workarounds.

Thank you very much for your help and advice.

Best regards,
Dario

Hi, Dario:

My understanding is the last BIOS update for the model series was F.29

Solved: HP Notebook - 15-ac133ns (ENERGY STAR) BIOS and Hard drive d... - HP Support Community - 939...

I can give you F.24 too if you want:

There is no such file on HP's FTP server as sp77968:

W11:

I would do it if you want to stay current with cumulative and security updates after October.

I updated my HP 350 G1 notebook to W11 a long time ago and it has an i3-4005U processor and W11 works just fine on mine.

I have a SSD in it and 16 GB of memory.

You can upgrade to W11, but you would have to use a workaround that bypasses the W11 hardware checks.

If you are happy with your PC, and if you are interested in installing W11 24H2 via an in-place upgrade on your PC as is, watch this video, which is the easiest way to do it in my opinion, and I have tried many different ways to do this during the last 3 years.

How to Install Windows 11 on Unsupported PC in 2025 (New Easiest Method, No CMD)

[NXR2]

Hi,

First of all, thank you for your quick reply. I downloaded the F.29 version you mentioned, and when I try to install it from Windows 10, the system asks me to restart the laptop to complete the BIOS update. However, after restarting, nothing happens — it just boots normally without applying the update.

I also tried creating a BIOS recovery USB, but I get an error when trying to launch the EFI files.

I'm a bit lost at this point. I'm not sure if there's something I need to configure in the current BIOS settings or if there's another issue preventing the update.

Thanks in advance, best regards.

Update:
Sorry, maybe the update method I used wasn't the right one. I’ve now successfully updated the BIOS using a Recovery USB and the Windows + B key combination in HP's BIOS Update mode — everything is working correctly.

My next question is: what’s the best method to install drivers for Windows 11 on this laptop? I’ve been using this link: https://support.hp.com/us-en/drivers/hp-250-g4-notebook-pc/7609933 and downloading the Windows 10 drivers from there to check if they’re compatible with Windows 11.

I tried Windows 11 on this laptop, but I had compatibility issues with the Intel and AMD graphics. The screen would go black on startup every time I tried to install the AMD drivers.

You're very welcome.

Glad you were able to update the BIOS.

Since you have one of the notebooks with the AMD/Intel switchable graphics, if the W10 graphics drivers don't work on W11, then I recommend you go back to W10 because that is a custom driver for which no W11 driver will exist.

If your notebook just had the Intel graphics, W11 would have worked with no problem.

One question for you:

Did you try doing the in-place upgrade from W10>W11 by watching that video I posted with all of the devices working normally on W10 prior to the upgrade?

Or was the AMD graphics adapter missing after the upgrade, where you had to install the AMD graphics driver?

Hello

The truth is, I'm having problems even installing the drivers in Windows 10. When I install Windows 10, Windows Update automatically updates the drivers, and the first reboot completely shuts down the screen. I have to start Safe Mode and uninstall the graphics driver.

I'm not sure if I should just install the Intel driver and ignore the AMD driver. What's your recommendation? I just want a stable OS installed, and it will be used for office work.

Thanks, best regards.

Hi:

Yes, you cannot update those drivers.

What happens is Microsoft is installing an updated drivers as if the PC did not have a customized graphics setup.

With the HP graphics drivers installed, immediately run the Microsoft Hide Windows update utility that I zipped up and attached below.

The utility will find the graphics drivers from Windows update pending to install.

Check the box(es) to hide the updates.

The utility will run again and report the problem is 'Fixed.'

Close out of the utility and you should not have that issue again.

It you try the upgrade to W11 again, run the hide Windows update utility again to prevent those updates from installing in W11 if they show up.

Hi,

I managed to install Windows 11 using the method you suggested and with that tool. It seems to be quite stable and smooth—having an SSD and 8GB of RAM appears to be enough.

Thank you very much for everything; I’ve marked your first reply as the solution.

Best regards.

[Paul_Tikkanen]

Anytime.

Glad to have been of assistance, and I'm glad you were able to get your notebook to run correctly on W10 and W11.

You will need to repeat the W11 upgrade procedure again when W11 25H2 is released to the public because an unsupported PC will never get any new builds automatically.

There may be different videos by the same person that did that video and by other folks, that come out to do in-place upgrades because Microsoft seems to make minor changes to the new builds that may prevent what worked one year from working the next.

Each build will only get the cumulative and security updates for the build that is installed.

Each build gets support for two years.
