Lenovo IdeaPad 3 15ADA05

[peste]

Hi, I need a BIOS file for Lenovo 15ADA05. The machine turns on without video, there is fan spin all voltages are present (3.3v, 5v, 19v) and the power button LED keeps flashing. It powered on once and gave TPM error message. I've tried the Novo button and disconnected CMOS to reset but to no avail. I suspect the issue is the on board RAM so if anyone can also provide me with a BIOS that has the on-board RAM disabled for troubleshooting as well I will also be gladly appreciative. Attached is a dump I was able to pull off the BIOS as required. Thanks in advance.

is working thanks

there is a hole on the side of laptop, pressing on the switch inside that hole you'll be able to enter in bios setup, take from there serial no

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...

[volinakis]

So... i could never go to BIOS... thats why i think there is a problem and wanted to test with another BIOS.... I don't know if there is any keyboard combination to Activate something which let me in BIOS.
I don't think that another thing is wrong... even i can't take out RAM couse they are SMD and soldered.

Thanks anyone for your help!! I hope this case could help others!

Namaste!

Hello, could you help me extract the EC.... I tried with this copy but it didn't work, my equipment came with a wet EC and it was replaced, I don't have the serial number labels.

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.

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, but i have the same problem... BIOS is not working, just the LENOVO Logo. When I try another option, is the same... just goes to LENOVO Logo and get stucked there.

When I take off SSD m.2 the computer says:
"Verifiying shim SBAT data failed: Security Policy Violation
Somthing has gone seriusly wrong: SBAT self-check failed: Security Policy Violation"

So I realise that there is SecureBoot ON.

So... i could never go to BIOS... thats why i think there is a problem and wanted to test with another BIOS.... I don't know if there is any keyboard combination to Activate something which let me in BIOS.
I don't think that another thing is wrong... even i can't take out RAM couse they are SMD and soldered.

I'm sorry but i didn't follow... Soyo SY-7VBA133U points to another user asking for correct bios, do you reffer to DMI copy ? from what i have been reading DMI doesn't male power led blinking but windows uefi key and other issues right ?

Edit: i think i got the problem, when i write BIOS and next when i read it results are the same. I am using clip and i think i will need 1.8v adapteur am i right ?

If your chip is Winbond 25Q64JW you will need a 1.8v adapter, because W 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.

Hope could be helpful!

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 ?

Please attach your backups directly to your post in a zip or rar.

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 25Q64JW
Made 2 copys.

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

Again, thanks for all your support!!
