Clevo BIOS Thread

I think he was. I can confirm 100% that the P170EM can boot in UEFI mode.
The oldest Clevo laptop that I know to be able to boot in UEFI mode is the M570TU with BIOS .19. It's a model from 2008.

 

Hi noob question but I can't find an unabbreviated answer anywhere:

What the hell is the EC and why should I care that I am currently on 1.00.11 while 1.00.14 is available?

 

EC = embedded controller. Small chip that controls vital functions like fan speed and keyboard. Update if you're facing issues, otherwise leave it alone.

 

Hi @Bester,
the "Embedded Controller" is a micro-controller that manages various real-time aspects of the PC (not handled by the CPU) such as screen brightness, external monitors, laptops battery charging and management, mouse and keyboard control and so on, while the BIOS is a program used to perform hardware initialization during the boot process (and provide various services as well).
Both BIOS and EC can be updated separately, they are totally different "environments"
Best,

Brilliant. These were both very helpful. Thank you both, I think I'll leave it alone.

 

Fan control is often a big one handled by the EC so fan behaviours can change.

 

Hello Meaker@Sager.

Have you got an Instruction how to do about EC flashing ?

 

Usually you do it as part of a BIOS flash.

 

OK, is there an example of where to look or how to do it? I have a bios programmer and a bit of experience with it but unfortunately not enough to follow you

 

Oh to program it manually? You take your flasher program once clipped on, dump the existing contents into a backup, then program it with the file you want. The exact procedure depends on the board/software you are using.

 

Is there any way you can help me with my project?
I have a 341A Programmer with Clip 8 pin for the BIOS.
I would pay them something for it too.

 

What software are you using?

 

Hello.
Razor Blade 17 Pro 2020 with Synapse Software

 

Software for the programmer.

 

Oh sorry......

 

Damn that is beyond me. I couldn't imagine making my own BIOS update haha.

 

hello guis, iv got a problem updating the bios for the p775tm1g

first i updated the EC wich worked fine, but updating the bios giving me errors. i cant get it updated ? any help wud be appricited!

 

hi guys
asking b/c I do not see my model listed. I have an older np9772, I just want to make sure I grab the right bios version. my video card is acting up, trying to eliminate possible issues. I have messaged my CS but it is a Friday
thank you!

 

Ask Sager about their BIOS. don't cross flash a Sager with a CLEVO BIOS. Sager should be able to assist

You might have to settle for older drivers. I have a GTX1070, and I can't use the latest NVIDIA drivers. Yours might be even older.

 

thanks I have reached out to them!

 

thanks, where do you find their old drivers at?
they had been doing well up until this new yearish

 

Try these:
https://www.sagernotebook.com/drivers.php?cat=608

 

https://www.nvidia.com/en-us/geforce/drivers/ Manual search, select your graphics adapter under notebooks and search, then scroll down to see the older drivers.

 

thank you. I think my vidcard/gpu are going.
I will try that tonight. I actually restored to a prior windows back up and that did not solve the problem
I used a driver from september, that did not work.
I did a windows reinstall. that did not work.
currently, it is working with the vid card disabled.

 

thank you will check it out

 

Ouch! Keep a close eye on GPU temperatures, and other temperatures too. Plenty of utilities out there that will chart the temperatures for you. For all you know, it might just need a good cleaning and repasting. Fingers crossed.

 

planning on cleaning it shortly, thank you. I am hoping that is what the problem is. I probably should have done it prior to resetting windows lol

 

well a good cleaning changed nothing. I tried multiple old drivers for the 970m. I wonder if this card is just dieing
waiting to see ifthere is a bios option. I am not sure if the 970m is something I can replace or not.

 

Hi,
I need last Prema bios for Clevo P170EM.
Is possible that?
Thanks for your help!

 

Only Prema can give it to you. Unless he decides to make his older BIOS public. @Prema ?

 

Does Prema still post/view these forums? I bought a system that came preloaded with the Prema BIOS and I think there is a bug in it that causes the internal keyboard to stop working. I'd like to submit a bug/jira issue but I'm not sure where that would be.

 

I don't know if he does. You can PM him and maybe he will get back to you. You can also contact him through this website: https://premamod.com/

 

Perhaps I will try here. I have an x170sm-g and recently added two new RAM sticks. Then my machine started freezing and acting strange. So I was told to up the RAM voltage from 1.2V to 1.35V but I am not sure how to do this. I have the Prema mod installed, but I cannot see how to edit the voltage. I see it listed there, but no edit option. Anyone know how to do this??

 

If you click on the 1200 and just type 1350, won't that work ?

 

Nope. I figured it out. I have to change from default profile to custom profile first. Then everything is editable. Thanks.

 

Awesome!

 

I would really like to do this as well can you explain what you did. Thank you

 

Yes. I went into the Prema Mods -> Advanced -> Overclocking Performance Menu -> Memory. From there choose custom profile and simply edit the value you wish. Save and boot.

 

@Blacky

Hey !

I think I have a Newer version of the BIOS for the P770DM-G, where Can I provide the files ?

 

Ah, Wow. I haven't really maintained the initial post in a while because now we get the BIOS / EC from here: https://repo.palkeo.com/clevo-mirror

But yeah, yours is newer than what we can find in Palkeo's repo. You can upload it to megaupload or some other file sharing service and I will add it to the initial post.

 

There you go

https://www.mediafire.com/file/ovjljpd20c4nym7/X6BIOS_B0517.zip/file

I advise you to download them and upload them where you see fit, I cant guarantee the files not being erased or blocked in the future due to inactivity.

cheers!

 

Hi all,
I'm Timo and am new here. Following this thread I was able to get service manuals and also a new Clevo-BIOS Update for my Clevo NV41ME - thanks for that!
However I'm now experiencing problems. I figured here are some Bios-Experts and people with good Clevo-Insights involved. So maybe someone has a hint for me:

After the BIOS update to 1.07.05 (from palkeos mirror for my model) the Thunderbolt 4 port was not working anymore. Am I missing anything? Spoiler: I was able to revert using my BIOS-dump (1.07.04) (made using a ch341a+clip).

Things I did:
- Make an EFI-Boot-Drive on USB
- Place BIOS/ALL folder on USB
- Boot into EFI-Shell
- Unlock ME using MESET.efi
- Reboot into EFI-Shell
- Flash ME+BIOS using FLASHME.efi (or nsh?)

Instead of flashing using FLASHME.efi I also tried flashing using FLASHALL.efi without better success.
To revert back from 1.07.05 -> 1.07.04 I first used the stock bios provided by the palkeo-mirror. Here I ran into the same issue (thunderbolt not working).
Finally I flashed my own BIOS-Dump using EFI-Shell and FLASHALL.efi. Afterwards everything worked as before.

Thanks in advance
Timo

Sidenote:
Inside the 1.07.05 archive are release-notes stating:
1.07.03:
"[...] 1.SUPPORT RETIMER F/W CAPSULE UPDATA [...]"
1.07.04:
"[...] 2.Add Keep TBT Re-timer capsule update info solution. [...]"

Maybe due to this "capsule solution" the thunderbolt portion is not updated properly? Do I have to extract anything using uefitool or just update a portion of the Bios using a special command?

 

Generally in such a situation either wait for a new BIOS update or email whoever sold your laptop about the problems you had with your BIOS update. Generally, these problems will get forwarded to Clevo and make their way in a future BIOS update.

 

Hello,
I have prostar N850EP6,
bios 1.07.09Px
KbC/ec 1.07.05
Don't have responce from vendor....
Last clevo updates:
Bios. 1.07.13
KbC/ec 1.07.07

Is it critical if I flash and update my laptop?
Best regards

 

Look at the BIOS updates in the palkeo link in the initial post. See if any of them have any critical updates.

 

Thank you, I took versions from palkeo link.
There is no any information in redme files.... Just new versions.....

 

Ahh, they don't write anymore. Clevo used to write next to the version number what they fixed.

 

Dear all experts,

I am seeking advise on bios update in a old laptop laying around.

It is a re-brand of clevo P650SA - Aftershock -S15. The current bios:1.03.03 + EC:1.03.03.

Can i upgrade from 1.03.03 directly to 1.05.01 or I have to follow the version order.

Please help.

Thanks.

 

There is nothing in Clevo BIOS file info that suggests you can't do an upgrade straight from 1.03 to 1.05. Just make sure you upgrade the EC first and then the BIOS.
