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.

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...

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.

Never mind I have tried 5 different BIOS but no sign of life, moving on to diagnosing.
Thanks

Hello EveryOne,

I have a Lenovo Ideadpad gaming 3 15ACH6 LA-L171P Rev 1A that is not reacting to power button press (no LED or fanspin)
After a shorted EC chip replacement I have found that BIOS chip is full empty so cannot post it. (I'm guessing that is why RSMRST not rising after button press)
S/N: MP2E5TCK
Thank you
