Lenovo IdeaPad 3 15ADA05

[cusspide]

Well, I'll contribute something to see if it helps.
IdeaPad 3 - 15ADA05.
I can't enter the BIOS. Nor can you boot from a pendrive. The machine with Win11 and with a mechanical disk. A real turtle.

We offered the client SSD disk and Win 10.
When you press F2 or Fn+F2, it freezes on the logo. The same when pressing F12.

I chose to update the BIOS from Windows itself (It works, slow but it works), from the LENOVO website, where they flashed me with version E8CN41WW. I restarted, the process started, it finished and when I restarted, it died. Not even the Logo comes out.

I'm going to do it with the RT809H. Thanks LENOVO!!! (tremendous rubbish)

As I can dump some BINs of devices that work at 100%, I will upload them. Greetings and thanks for your help.

Well, as expected, I copied the BIN, this one and it worked

Again with Setup and boot selection. Thanks TRACKER1

I upload the flashed bin according to the Lenovo method downloaded from the same website. It crashed and didn't start again.

Thanks a lot !!!

Hello everyone!! I'm from Argentina... i have an Ideapad 3 without any sticker... so i don't know which exact model is my laptop.

I think is IdeaPad 3 15ADA05 (looking for some pictures i notice that is the same...)

MainBoard: GS450 & GS550 & GS750 NM-C821 REV:1.0 2019-12-05
BIOS: Winbond 25Q64JWSIQ

Basically the first time it goes with problem was showing a BlueScreen, and not booting Windows getting stuck in LOGO.
Then it just get stucked reading SSD, showing the "loading icon" but nothing happends.
So i try to enter to the BIOS but nothing... just stuck in LOGO.
Using NOVO button... is the same... not booting BIOS.

So i think this problems comes from BIOS... i don't know if there was any upgrade.

Someone else had the same error?? I wish to try reflashing BIOS, but i don't know so much...

What do you recomend? Thanks in advantage.
