Greetings to all.
I have a strange problem with an Lenovo Ideadpad gaming 3 15ACH6, to be more detailed, laptop worked fine for at least 1 year and from a few days ago laptop won't boot into windows, it gives bluescreen witn ntoskrnl.exe and, tought it's from OS or hdd or even Ram, but all of those are fine, even if i try to do a fresh install with W11 it give's bluescreen with page fault in nonpaged area.
So tryed with a good Ram, even with another good SSD, tryed with more USB drives with media creation tool for os install, same problem. It give BSO at windows load or windows installer load.
next i tryed to update bios, but only chance to do it was with recovery procedure and it worked to update bios but not the EC too.
So to eliminate this possibility of let's say incorect EC dump or incompability from EC with Main i wanna ask you for a clean bios and EC dump.
If this won't work out then the only option remain that the problem to be from CPU and it should be changed/reballed.
if it can help, i can enter in advanced bios setup with the secquence of F2-Fn+R+N-F10-Yes-F2, maybe you got some ideeas of what i can change from there to bypass this problem (maybe increasing some voltage of Ram or CPU, or increasing some page file if exists)
I atached readed dumps from the MB and the official update from lenovo(H3CN47WW).
SN is :MP2NJ5MP
Mb is GOG20 LA L171P REV 1.A

Another thing forgot to ask - i dont have any soldered gpu ram (someone desoldered before), without it should it post something on screen?

[SMDFlea]

Should I copy my S/N and how do I do that if required? Is it required to just boot laptop without copying anything to test?

You can try them without the serial, it can be added later.

The laptop has four bios versions...the laptop's bios is corrupted and the bios version cannot be found...try the versions from post 83 one by one...

The DMI offsets don`t look right (for the 82k2) ,i think they should be

EA5000 - EA6FFF

EAA000 - EAA03F

Hello i need BIOS, i Think someone before me broke that and tried do something with flashing (soldering of chip) and now laptop only spins fans and LCD is light up but nothing on the screen. All voltages are ok, battery is chargin.

None taken, we are here to help each other I think.
My oppinion is that replacement accoring to my comparison link and your bios datasheet W25Q128JWSIQ is better for your replacement because its maximum Maximum Clock Frequency is up to 133Mhz and your GD25LR128D is up to 120Mhz
(w25q128fwsig is only 104 Mhz) but someone correct me if I wrong.

Thank you very much, all works as should.

Thank you very much. Will update end of next week.

No disrespect, but I'm sure everything with my programmer CH341A and drivers is working fine. I'm still able to read other chips without any issues. That's why I'm asking for alternatives to GD25LR128DSIG.

CH341A supports this chip with Neoprogrammer. I have used it before.
If you cannot detect chip with the program then either your driver is not correctly installed on your machine or the legs not tuching, OR chip is faulty.
Try reinstalling the driver first and check leg connection with multimeter

Thank you for your reply. I'm using Neoprogrammer, and the original chip I was reading as GD25LQ128C. The new chip doesn't work at all—it's not responding. I'm connecting it via a 1.8V adapter and holding it on a clipboard; I also soldered but not reading.

Thread merged. Your programmer is a CH341A, what software are you using with it. The chip is probably ok, it`s just that the programmer can`t detect it if the chip is not in the supported list. You can try to write to it if you choose W25Q128FW

Hi, I mentioned my laptop earlier—it's a long story. The BIOS chip (GD25LR128DSIG) has a broken pin. I ordered a replacement from China, but it seems to be fake, as the programmer doesn't detect the chip at all. My question is: what is its equivalent? I don't want to order another one just to find out it doesn't work again. I checked the W25Q128JWSIQ and W25Q128FW, but I'm not sure if they're compatible. Please help. Thank you for your time and response.
