Lenovo IdeaPad 3 15ADA05

[borgesbe]

Hey there, have tried all BIOS on recommended posts, but still Ideapad3 15ADA05 has power blinking light with no image. SN is PF24W3TN, MTM 81W100EDPG, model name 81W1 and i did a bios dump before trying other versions. Can anyone point me in the right direction ?

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

Thanks anyway! <3

Look for a label on the laptop case.

What is your serial number ?

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 25Q64JW
Made 2 copys.

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

Again, thanks for all your support!!

Thanks peste for your answer!!

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!!

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.
