Problem reading bios chip with ch341a and with clip

Hello, I am trying to read the BIOS on a Dell Inspiron 15 5559 motherboard with a Winbond 25q128fvsq bios chip and when I connect the clip on the chip and plug in the programmer into my computer and even trying every version of the ch341a programmer software and asprogrammer, it fails to detect the chip. What am I doing wrong?

@Linas81 - For W25Q128FV you need to use 1.18 version CH341A software (for valid read only), or use ASProgrammer 1.41, otherwise other versions always fail (at read sometimes, but write always).
For write to this chip, only Colibri (included below) or ASProgrammer has been confirmed working here by others

If you continue to have detection issues, you may have it setup wrong, or you may need to connect 4/8pin and 24pin PSU cable, some systems need those connected, some need them removed.
Here is guide with lots of images, so you can be sure to connect it all properly (DO NOT rely on what the little image shows for chip orientation in the software)

Thanks, those suggestions worked.
