Can't use Linux due to BIOS update, any way to flash another BIOS?

[Dinkle]

Hello and good day!

Over the years of using my laptop, it suddenly started to crash any/all versions of Linux, kernels and distros (pretty sure it was a BIOS update), making this laptop useless outside of windows - which now has become unbearable with microsoft's recent update history.

I'm 99% sure that the fix is to disable the C6 (which is infamous to cause issues with Linux) and higher power saving states on my Ryzen 7 5800H, but I can't do that on the Linux side - it crashes/perma-freezes during boot/few seconds after, so I have no time to install/make any changes.

Disabling it in the BIOS would be a permanent fix, and I've already seen that the option IS available when using AMI's BIOS tools.
Only problem is I can't access that specific setting in the already existing advanced BIOS options, and have no easy way to flash the modified BIOS .bin file (to make the setting visible to me)

Is there some easy way to get around all that which I don't know of? And/or can an authorized HP service center help me with these things?

(HP should give their advanced users more freedom instead of treating them like clueless kindergartners.)

Proper help would be very appreciated - thanks and regards.

Edit: I have the latest available BIOS installed (AMI F.27 21/10/2025)

Hi @Dinkle,

Welcome to the HP Support Community!

Thanks for reaching out, 

I understand how frustrating this situation must be, especially when it limits how you want to use your device.

At this time, HP officially provides support primarily for Windows and macOS environments. Since your concern is specific to Linux behavior and low-level BIOS modifications for Linux compatibility, this would fall outside the scope of HP’s supported configurations.

For more specialized help, I recommend reaching out to Linux-focused communities and experts who regularly deal with kernel, BIOS, and hardware compatibility issues:

See The Linux Kernel Archives (in English) for general information and updates about Linux.

Ubuntu: http://www.ubuntu.com/ (in English).

Red Hat Enterprise Linux: http://www.redhat.com/ (in English). For home or personal use, see http://fedoraproject.org (in English).

SUSE Linux: https://www.suse.com/ (in English).

Novell SUSE Enterprise Linux: https://forums.suse.com/forum.ph (in English).

Regarding BIOS modification or flashing custom BIOS files: HP does not support or recommend modifying the BIOS outside of official updates, as it may permanently damage the device and void the warranty.

I hope this helps.

Take care and have an amazing day ahead! 🚀

Best regards,

Kuroi_Kenshi

Greetings @Kuroi_Kenshi,

Thanks for the response,

And yes while it's frustrating, I understand that it's also a complicated or unusual situation - so I'm not trying to make a big fuss out of it - but seems there might be no way around that.

I do not require support for Linux - rather just the bios itself, I want to be able to use my PC in the ways that fit me and my needs, not just what is more profitable to a corporation.

Please understand that this BIOS situation from my end is VERY close to ransomware - being hacked (BIOS auto update) and demanded ransom (I can't access my linux work/content unless I pay HP for support).
Or if preferable, we can go with terms like "support-based extortion" or "manufacturer-induced lockout."


As for the resources - thank you for the links and BIOS info, but I have done enough research to know that anyone else who had the issue, simply disabled the lower (or higher?) C-states in their BIOS settings, or installed the zenstates python script (which again, I have no time to do before my laptop crashes)

Thus please, if possible, give me an 'official' BIOS update with the C6 and C7 CPU states disabled (or changeable), as that should fix/stabilize my system. Lastly if it makes a difference, I don't have any warranty on the device - as I usually know what I'm doing.

Regards, and again - thanks for the effort with replying.

I gave up on trying to change the bios, but ermm.. now it seems to be happening on windows as well - and apparently it gets a whole lot worse (with system freezes on top of the random crashes) when I stop using the performance power plan (e.g. switch to balanced mode - or etc). I also recorded a video of the system and laptop being frozen - how can I share that?
