Lenovo IdeaPad 330S-15ARR - 330S_ARR_V06

[Assembler]

Hi, have a nice day, i have a Lenovo Ideapad 330S-15ARR 81FB Ryzen5
with Serial number: YD04X9L9
MO: YDN0B862801V
FACTORY ID GXSC
MTM:81FB005WIX

stuck on ubuntu uefi voice for startup, every linux boot is freezing with a cursor on a top left of screen.
can i have latest bios with correct serial (i think the serial is wrong because the motherboard was replaced/fixed) thankyou!

hi every one
i had thesame Lenovo IdeaPad 330S-15ARR
it was no power

found out it has short on main power rail
ive tried to find the schematic for the board but failed.
so i tried to check what is heating up,, found the mosfet frying itself,,
ive removed the mosfet and injected 19v to the source( not sure yet if what type it is)
ive done this because there are so much short caps around that area,
then I found a bad cap very far from where i expected,
its a filter capacitor,
when removed, finaly i had charging light but no display, i suspected that i may had a currupted bios
I did used the posted bios from this thread but didnt work, i looked for another bios chip that is work for 1.8v then I rewrite my old bios file, the the thing came back to life

note: the mosfet is q5901
the bad cap has no label, i can send a photo
I will upload my bios file for the future errors related on bios. this is working bios file

Thank you very much.It worked for me.

I didn't say you were wrong.
I can't tell if it would work with

00 FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF

but with

FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF

it definitely works

Sorry, I'm not an expert, that's why I'm asking.

After some time I came back to it. I did
1. cut the beginning of the file from 0 to 0000317 (792 bytes) see
2. cut the end of the file, everything from offset 0080000 to the end 008881D0 (557528 bytes) see
3. I replaced DMI offset 001EE000 - 001EE220 (560 bytes) see
Now the file has the correct size 8388608 bytes, but the md5sum does not match your file

I searched for the problem and compared the files.

BIOS.my BIOS.volinakis differ: byte 11588379, line 126499

see offset 01EE220
my

00 FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF

your

FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF

There is only a difference between 00 and FF. Either I am wrong or you are.

for sure i am wrong, that's why "I uploaded the one you gave me to the bios. I started NTB and it works great." ...

I don't even know where to start ... read bios guides of this forum, you don't even read what I wrote ...

my bios start with hex 0100 003e and you cut from 00ee 606c - 48 more bytes ...

Try to insert the clip several times and read again. As I already wrote, I managed to make a clip after 5-6 attempts. If you don't succeed, de-solder the chip with hot air and use an adapter.
I ordered this and there are more options than flashing the bios

BTW, I'm not an expert, I'm just a consumer too, just trying to help.

[fmarquis]

Yes I used a clip and the 1.8v adapter, it tooks maybe 7-8 tries for it to work and read something that wasn't full zeroes.
The extracted BIOS looked fine, I extracted the bytes required and put them on the template bios found on this thread.
But now, I can't seem to write it back :/
Is there a way to know if the chip is not dead ?
If it is, can I order a new blank chip and try to switch it on the motherboard (won't be easy with my fat fingers :/ )

[gusto]

Did you use a clip or another method for writing and reading?
I managed to clip after 5-6 attempts.

[fmarquis]

Hello,
I read all this thread again and again, bought a.programer and managed to read my corrupted chip. I extracted all required data and put them on one of the template Bios from this forum.
But now I can't seem to write the chip with the new bios. I think that I may have burnt it :/ The software can't detect it.

What can I do ?
Buy a new chip and try to replace it on the motherboard ?
Is there a way to confirm that the current chip is burnt ?
Thanks

hello, anyone with an advice on the best next step in my case ?
Thx

[volinakis]

I followed post number 29. I found the region 1EE000 - 1EE22F and replaced it.
However, I do not know if it is enough to replace only this region 1EE000 - 1EE22F (I did not replace the Win key)
The BIOS you sent me starts in the hex editor like this


I edited the BIOS in the hex editor as it is written in # 29. However, it is not written anywhere that I have to cut the beginning and end of the file.
I am also attaching pictures and a file that I edited. It should match the one from volinakis (however md5sum doesn't match).
I don't have NTB at the moment, so I can't check if mine is correct.
