Lenovo IdeaPad 3 15ADA05

I am using a cheap CH341A programmer, and I do not have any backup. Do I have any chance to bring the laptop back to life again?

CH341A has at least 3 software support.

I know, I used the NeoProgrammer for the back-up, but I already flashed another bios to the chip, and now I do not have anymore the original one

I can give you the file from the Lenovo homepage, but it doesn't have the DMI since you don't have the original file.

Update ? ,is the laptop working. Explain what the problem is

[polete2007]

The problem is that when I start up, I get an error in MS-DOS about the newly installed CPU and other times a blue screen appears, and I have the latest BIOS installed from the Lenovo website, but the PC is unstable.

All the bios posted here need flashing with an SPI programmer.

Hello everyone,

I had the problem 2 days ago when updating the bios that it froze. Even after a good 5 hours the status has not progressed a bit. After forced shutdown and restart everything stayed black and nothing reacted. Thanks to this forum, I read out the bios with the CH341A and saved the non-functioning ones first. I then uploaded the file from the forum to the bios chip. PC and Windows starts but Win11 complains about the missing key. In the bios the information about serial number, key and so on is missing. I also have a photo of the information page of the bios before I tried the update.

Now the bios version E8CN41WW is installed and working

Can someone help me to get the information into the bios file, it would also be great if the Preinstalled OS license would be possible.

Product name: IdeaPad 3 15ADA05

Many thanks in advance

Need help for BIOS password removal.

Lenovo Ideapad 3 14ada05
S/N: PF2LY3HP
MTM: 81W000GCID
Model: 81W0

I can't use F2/Fn+F2 and only accessible via Windows UEFI Firmware. just in case it is needed for advanced.

can the password still be found in this bios file?

post merged...next time look for a thread with the name and model, motherboard model of the laptop, and post there, if you can't find it, then make a new thread..
