Re: Lenovo IdeaPad 330S-15ARR - 330S_ARR_V06

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.

my

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." ...

[gusto]

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

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.

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 ...

If I can see correctly, I looked for the PHCM sequence in BIOS.cap and it looks like this (region starts at 00000310):
Otherwise, I have to delete everything up to line 0300 (including)

This looks more like the BIOS you uploaded to the forum.
However, it still does not match 8388608 bytes.
So I moved to the end of the file (extracted from the original BIOS (NTB)) and saw that at the end offset 007FFFF0. I deleted everything from offset 00800000.

Now the file matches closely with what I extracted from NTB.

-rw-r--r-- 1 gusto gusto 8388608 okt 31 10:42 BIOS_test.cap

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.

[volinakis]

I would like to ask again.
Using innoextract in Linux, I extracted this from the exe file

If you notice the BIOS.cap has 8946928 bytes. However, the file BIOS.bin.zip that you uploaded to the forum has 8388608 bytes.

Am I making a mistake somewhere when I open BIOS.cap in the hex editor?
Do I still need to do something with BIOS.cap?

read what i wrote in previous post: you HAVE TO edit BIOS.CAP in order to get right length. you are welcome.

you have to use innoextract to get bios image from update. Then edit with any hex editor to get right length - 8.388.608 bytes. Then transfer DMI.

try this one:

I used innoextractor and extracted bios.cap, but there was no match out of 8,388,608 bytes.
So I uploaded the one you gave me to the bios. I started NTB and it works great.

[volinakis]

Thank you. I followed your instructions in post #29.
First, I downloaded the official bios for my NTB from lenovo's website.
I'm not sure if I extracted the bios bin correctly from the exe file.
I used the 7zip program to extract. From the extracted files, it seems that bin will be this file [0] (6575 Kb). However, when I open file [0] in HxD, I don't like it at all (I am attaching file [0]).
Can you please check if [0] is really correctly extracted from the exe file?
