Re: BIOS medion S6426

Hello Luke, unfortunately this IS indeed a very serious BIOS update issue.

Like already said and proven above.

 

I know too because I got the same problem on mine Smiley Sad

MEDION AKOYA S6425 (MD 61072) 

MSN: 30024625

 

Reinstalling the drivers did not improve the problem, even reintstalling the complete system to factorystate with PowerRecover did not solve the issue.

So this is 100% a bad BIOS version.

 

Of course the above linux solution only apply to the 5% of people who got Linux on their laptop, not Windows. Smiley Sad

 

- And another nasty thing this update did was making the system a LOT slower.
On an average of 3 benchmarks before and after the BIOS update to version 209, the CPU score went from 9300 to 7300 points in Passmark!
(That is a decrease of 22%!) My laptop makes a lot more noise and gets hotter too because of this...

 

So please Medion, work for a solution on this, or I'll have to turn in my laptop to the store while I still can.

Re: BIOS medion S6426

 Hello tec9,

 

Hmm, unfortunally, Linux is not all sunshine. It's impossible to use the headphones on the PC. So there is still something wrong.

 

I also tried windows afterwards, but sadly, I can only confirm what you are saying. I tried a clean install of windows, update of the drivers (downgrading the drivers), every possible update there is for windows; but no sound available. Strange, because before the bios update, it was working perfectly! I guess this is the reason why they deliver the PC with an older BIOS firmware, however, it would be nice to get some help from the Medion-experts.

 

So, for the medion-expert, is there something we can test further? Do you need more information from our side? Can you confirm maybe what we are experiencing, or is there another reason why the PC's are delivered with version 207?

 

Greetings,

Re: BIOS medion S6426

Got same problem on S6425

 

How come such a BIOS update did pass quality control?

In my case, when enabling CSM (?), I could not enter BIOS anymore, and system refused to start up, whereas in 2.07 that worked fine.

Had I known this I would have NEVER updated.

 

Could somebody make a version to go back to version 2.07? See

Re: BIOS medion S6426

It should not be too hard for Medion to give us a Bios update with the same content as 2.07.

 

For everyone who got this problem I would contact Medion and explain the situation (I already did)
You can contact them by filling in the contact-form on their service-portal: ex: 

https://www.medion.com/gb/service/contact/

https://www.medion.com/nl/service/contact/

https://www.medion.com/be/nl/service/contact/

https://www.medion.com/be/fr/service/contact/

...

After the contact form you will receive a mail with some tips and faq, then you have to reply to that mail that it did not solve your problem so they will create a "real" ticket and send it to their product specialist.

Re: BIOS medion S6426

Going back to 2.07 not possible? Of course it is!

 

Medion should just make a new download available that will allow a BIOS update to version 2.07.

If needed, such an update can be relabeled 2.10 or whatever.

 

However, I doubt that is necessary, as the the InsydeH2O FFT tool used to upgrade BIOSes has an option to NOT check a version, so it can be used to downgrade. But that is up to Medion to fix.

 

Medion, take your responsibility and fix this for your users! It's really bad to push such a BIOS version to the whole customer base.

Re: BIOS medion S6426 / S6425

I think I've found the V2.07 BIOS.

I'm not sure how long this link will be kept alive, so be sure to get a copy here

I did a binary compare with the V2.09 BIOS, and it seems the V2.07 is LARGER, i.e. contains more data. It looks like it has more assembly code parts.

Maybe someone is willing to try and install this version, or at least check if it is applicable? I'm currently not able to do so.

If you edit the platform.ini file, you can at least disable automatic install, but let the software check if it is suitable to be installed.

Do not know the option by head, but will check.

Re: BIOS medion S6426 / S6425

Yes, In the meanwhile I noticed you can't download the BIOS version 209 anymore from the MEDION site and they reverted back to 207.

I also got a response from MEDION that they send the case to Medion Germany for a solution.

 

I told them I want to go back to version 207 as it's not just the sound problem but also the >20% speed decrease from the CPU.(It's like your pc suddenly aged 5 years).

Re: BIOS medion S6426 / S6425

Great that they're further looking into this, but we really need a solution in the short term. Now we don't know how long this will take, and what the solution will look like.

Re: BIOS medion S6426 / S6425

Medion has released a BIOS recovery from 209 to version 208.

After this, the sound is working again Smiley Happy

 

The CPU benchmarks are still not as good as version 207, a 400points decrease instead of 2000 points with version 209.

Re: BIOS medion S6426 / S6425

Hello,

 

yes, 208 works for windows. But for future persons: Linux is screwed... I can only boot with acpi=off. So no battery indication, no mouspad working, no shortcuts with fn-key, ... Pfff, depresisng,
