Lenovo Thinkpad 20LT-S0KL1G bricked after writing the wrong eeprom

Hi,
I was given a laptop with a BIOS locked by a password. I read that one way to unlock it is to read the EEPROM contents, patch them, and write them back. I was using the typical CH341A programmer and clip to do this, but because the clip is so loose, after patching the dump I accidentally placed the clip on the wrong EEPROM and now the laptop won’t boot.

Can I do something to fix it? I’ve attached photos.

Thanks for responding so quickly. I tried it, but unfortunately it didn't work 😔.
The EEPROM chip is MX25L8005M, which is also 1MB.
Laptop serial number is PF-1D8PGY.
