W25Q80JVSIQ isn't bios chip. Find an other chip and post your serial number more.

Try one of this if it is as you wrote ThinkPad L590 (type 20Q7, 20Q8) FL490F L590 NM-B931 Bios Bin
Because of yoyr Serial Number its not a L490

My idea is that you shouldn't look for bios solutions anymore, go looking for hardware problems.
