ThinkPad X1C6 winbond 25q80dvsig chip dump request

[TamFishe]

Hi, I got a ThinkPad x1 carbon 6th gen from a friend after in an attempt to fix it he ended up bricking the motherboard. today i tried plugging the laptop to the wall and i got no signs of life, despite the connections being proper. i've found out this winbond 25q80dvsig chip under a label near the usb c ports and i gave it a read, and the output has massive chunks of 0000 0000 0000 0000 followed by FFFF FFFF FFFF FFFF and sometimes some proper values scattered across the whole chip. I've attached the file because I've read people request it in order to fix it. Moderators, if I've posted this in a wrong place, please guide me where to post. Thanks to everyone in advance

Post the laptop serial number. Has the 25q80dvsig been messed wth by your friend as it isn`t the bios chip.

The serial number is PF-1ELXLJ, type 20KG-S54200, i have no other info about the chassis or the motherboard itself. As for him tampering with that chip, no, he didn't touch it ; the previous owner was updating the bios on this and he forgot to plug in the laptop to charge to which then it died, passed it to my friend, my friend lost patience and didnt pay attention to remove the cmos battery and the main battery while reflashing a random bios, powered the laptop on, then a ceramic capacitor blew up and thats when i said to give me the laptop which i got this week on monday. As for the bios chip in present, I flashed one that i found for the 20KG model on indiafix, but I never powered the laptop on because....well besides today trying to feed it power and nothing was happening, i haven't fixed the capacitor issue either.

Update: I think It's probably the thunderbolt firmware, I'm not too familiar with it, but is it also a possibility that the usb c's aren't working when i plug in the ac adapter? I can also change from bios requests to the right category if needed

It is the thunderbolt firmware. Sort the cap issue and make sure theres no shorts on the power rails before going any further. If its all ok then find the bios chip, make a backup and post it
