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?

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.

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

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.
