Is it possible for a laptop to not turn on and even charging lights fail to turn on if you short out some pins with a screw driver on an eeprom chip?
I have done this with desktop computers and never had such an issue so I am not too sure if this is the same with the laptop?
If so is there a way to fix this issue, its a lenovo laptop?

Definitely… a laptop circuit is not the same as a desktop mb.
This kind of shorts affects laptop EC IC and IO IC… and if i remember correctly, you were using a Dell charger on this Lenovo…
Get the laptop mb schematic/boardview and start digging or to some one who knows how to probe it.

How come by putting a screwdriver on the eeprom’s pins can ruin its bios firmware? And why does this happen to a laptop and not the desktop motherboard?

what are those?
Yeah I was using a dell charger on the lenovo laptop. The laptop did not first turn on until I connected the dell charger to it and then I could turn it on no issues. The charger was disconnnected before opened the back and I put my screw driver on the pins on the eeprom chip.

Where do you think the point of failiure is, is it the eeprom chip that needs to be reprogrammed?
We dont know what laptop is or the mboard, so we dont know if uses several ICs for EC/TPM/ME/SPI bios, it can be corrupted data or damaged circuit… and dont ask to see this or that, im not going to lose my time to analyse anything remotely, good luck.
EDIT:
No they are not, what difffers its their connection to the mb circuitt and power dependecies…that ARE NOT always equal and this is where you #@$42#$%^, comgrats!!!
Ok at least I want to just understand soemthing on desktop motherboards are eeproms different to the ones on the laptops? I thought it would have been the same?
