Greetings, I wanted to back up the BIOS. Connect the EZP2019+ programmer. I did it without the 1.8V adapter. After removing the backup, I turned on my Lenovo Idea pad 3 computer, and it no longer provides video.
I bought a BIOS chip and installed a BIOS update
but the laptop still doesn't work.
Another part of the motherboard could have burned out.
Motherboard:

GS450/GS550&GS750 NM-C821 Rev 1.0​

Model: Lenovo Idea pad 3 15ADA05
BIOS Chip: W25Q64FWSIG
Programmer: EZP2019+

If I didn't use an adapter, could another part of the motherboard be damaged?
How can I fix the problem?
I already bought the bios chip and the 1.8v adapter.
Can you help me with a bios to test?

How can I know if it is a problem with the motherboard or the BIOS chip?
