Hi all!! Thanks for your help!

I reach the goal and fix the computer... The SSD m.2 was corrupt... and for that i couldn't enter BIOS normaly. But with other m.2 it works fine!

So... if you have same problem, just change m.2

Please, see all my post to understand whats happened to me.

Thanks again for all of you who bring help without wanted nothing....

Hi Volinakis, thanks for your help.
I already try that, even i explain all in post 194
All serial numbers that i have is from the webpage wich sends me the QR code from laptop label. Pictures attached in post 193

The NOVO button that you means does not work, when I select BIOS option, it does not get in BIOS, just go ahead loading OS, and stuck there.

I will try with another M.2 SSD just to see what's happening......

Just for refresh my problem...

The computer starts with Blue Screen Error... Client sends me a pic showing the Recovery instance with error code 0xc0000001

When I get it, i looked inside and saw that i was full of dirt. So i cleaned it.
Then I try turning on, and it allway get stuck "Loading Windows" in LENOVO Logo stage.
So i wanted to see BIOS, and pressing F2 or FN+F2, nothing happends, just LENOVO Logo without any loading, gettin stucked.
Looking for internet it says that this notebook comes with NOVO Button... i pushed it, Menú appear,...

Woow QR works and tell me wich computer ir... because there is no label just the ones in attached photo.

This computer is a IdeaPad 3 14ADA05 81W0 PN: PF2PRW41 MTM: 81W000MUAR
With AMD Ryzen 3 3250U and DDR4 4GB

Just for understand, why is important this numbers?? I really like to understand that... thanks for any kind of support!!

PD: my client was so awful taking care this computer... like you see in inside back plate....

If your chip is Winbond 25Q64JW you will need a 1.8v adapter, because [B]W[/B] is for 1.8v chip...

I attach datasheet.

You have to see first which voltaje is working... may be chip could works with other voltages but better use the intended for. Even you can test 8 pin for seeing voltage from the board.

I don`t know... there is no sticker anywhere... just a PartNumber inside moba: PN:5B20S44284...
That's all!

Thanks anyway! <3...

Hi! Thanks for your help!!

Here is the files... I did not take chip out from board. I used a clip with 1.8v adapter. Looking in the datasheet it says 1.8v that is the W version of 25Q64J[B]W[/B]
Made 2 copys.

Tell me if anything was wrong or right and how can i continue.

Again, thanks for all your support!!Hi! Thanks for your help!!

I have one CH341 "pro", same as video... I was thinking to make a BackUp and wanted to compare with others just to see if it could be any difference and try to fix it...
But i don't know if this is possible becouse differents hardware data or any code or key that is especific...

First will do a backup... So, what can i do then?

Could i try BIOS from #29?? but i need to put DMI info?? am i right? (i read all comments that day, i not remember correctly, sorry)...

Huge hug for you!! Thanks for all!...
