Request for PW removed Bios - Lenovo IdeaPad Gaming 3 15ARH7

[Chrisjacob]

Hello,

I am writing to request your assistance to provide an edited bios without password on my Lenovo IdeaPad Gaming 3 15ARH7 laptop:

Serial Number:MP2BKH42
Machine Type Model:82SB0001US

I am able to get into bios but not update any of the settings with password I have. So I'm assuming I need to reflash with unlocked bios. I can read bios chip withch341a programmer and get bios file off of computer. I also have updated bios file from manufacturer. Just not sure how to edit it to remove password.

Appreciate any help in unlocking bios file.

your bios is corrupted... read the bios chip again and post again...

Read the chip I can find but seems too small a file (winbond 25q16)
has a system password I need to remove - suspect the nvidia card has been disabled
Any help greatly appreciated

Look for chips with the number 256 on the back. Ex: W25Q256...

Try

Doesn't work - keyboard lights for 4seconds then off.
Motherboard is hlg50 la-m082p if that helps

No way, it's the original bios.

[alltalk]

Definitely - original bios works fine
The one you uploaded (thank you by the way!) is very different
By original I mean what was read from chip in the first place

[alltalk]

Need some help with this if anyone has some experience.
After trying one or two different files I've put back the original dump and laptop is now black screen.
No damage on the motherboard - whatever I do laptop now lights the keyboard for a few seconds then power light stays on but no video.
Wondering what to do now - try another chip?
Thanks for any advice!

So what would be the correct voltage for the bios chip?
