DMI transferred from your old bios backup:

Thank you very much,
I really didn't know why I couldn't change the information. I was validating your file and if there is DMI information in the sector 0x1000 to 0x2FFF, but your new BIOS file is encrypted on BC base and mine changed the encryption key to 54, FF, etc. I also noticed that it has more information at the beginning. Which method do you use?. Thanks for the help as all the information is in the BIOS. It seems to me that the motherboard was at some point replaced.

thx but power led blinking and fan turn processor work but black screen with my old bios and with new bios 😥

[Vesko356]

It's a virgin bios for your model with DMI transferred, you won't find any better bios, if it's not working your problem is not bios related, or you didn't program the chip as it should.

Here's your New bios file, it's a virgin bios from Lenovo with your DMI so it should works fine.
Next time find your device thread or create your own.

Hi everyone! 😀

Myself like most folks here a problem with BIOS as well (black screen, laptop boots up, LED's work), so I would like to ask if the Bios file from the post #12 would help my model?

I have tried all known fixes with unplugging CMOS, ram, battery drains... which ultimately led me here, considering the wide issue with this model.

Old (default) bios: GLCN41WW
Installed bios: GLCN55WW

Is DMI info unique for each model or do I have to do anything (make a bios dump from GLCN41WW or something) to have my version working?

Can I have a working bios with v55WW or a virgin v51WW is enough?

I'm new to the modding world, but I learn quickly, so I'm sorry if I haven't managed to follow something more thoroughly 😉

[Vesko356]

Use the bios at post #14, transfer the DMI block from your dump or if you can't do it yourself, upload your bios backup and someone will do it for you.

[pcG44k]

Tnx for the reply, Vesko! 😉

I didn't make any bios backups previously, so is there a way to extract bios backup/info or something else can be done?

Is CH341a (w/volt selector) with another adapter ok? Any better?
NeoProgrammer v2.2.0 should be used to dump bios from the chip?

[Vesko356]

Latest version of NeoProgrammer is V2.2.0.10
It's been discussed many times - choose the bios programmer according to your budget, please use the forum search before asking questions - you're starting to get off topic..

Good morning,
following an update of the GLCN55WW bios (under Windows 11) of my ideapad 3 15alc6, my laptop became unusable.
I have a Ch341a with 1.8v adapter.
I can read the chip and erase it well.

Is my "oldbios" corrupted?

Thanks for your help.

Hello and thank you for the reply,

Can someone tell me if my bios is not damaged?

For donations, ask one of the moderators, SMDFlea, Vesko356... some changes have been made, they could clarify for you......

Good morning,
With hxD, I opened the glcn52 file provided on this site and my oldbios file.
I then copied the range from 1000 to 2FFF from my oldbios which I copied and pasted by overwriting on the glcn52 file.
I haven't written about the chip yet, but is this the right procedure?
THANKS

[SMDFlea]

In your picture there are 4 F`s in the end-offset , it should be 3 . 1000 to 2FFF

[leno2021]

Oops !!!
it's a capture that I made after modifying the files, in reality I put 2FFF!!
Bravo for the observation!!

[leno2021]

Good morning,
I erase the chip with asprogrammer and the ch351a.

After modifying bios 52 I send it in the chip with the ch341a 1.8v
I know that for many this seems obvious but is my procedure for modifying my bios the right one?
THANKS.

[hopkok]

Hi bros, I change ofset 1000 to 2FFF in this file, but DMI is still the same, bad offset?
