Default Re: lenovo IdeaPad S145 bios needed

Hi guys
I have the same problem as many of you - flashing white power LED, black screen and no Vddgt power rail

I have attached my eprom dump. On my PCB the eprom is actually a 25B127DSIG. My TL866 does not support this.

According to the schematic (attached if anyone wants it) the chip should be W25Q128JVSIQ. This is not on the list of supported IC either so I used W25Q128BV and it appears to have read it OK

Can one of you smart guys give me a good data file

My laptop is
Lenovo Ideapad S145-15IWL
MotherboardFv440/FS441/FS540 NM-C121
Rev 1.0
CPU Core i5 8th gen
