Hi there, I have a ThinkPad X1C6 which I got cheap from a friend as I've mentioned before if you decide on checking my profile, but it has issues, including both the bios and thunderbolt firmware bricked. So far, I got a 20KG bios from indiafix, however, I still haven't figured out how to fix the thunderbolt firmware issue ( I feel like mentioning that I've never worked with FL1 and FL2 files or with any Lenovo product and I'd wish to not brick something beyond repair. ). Can someone with this same model of laptop give me a thunderbolt dump of the chip (Winbond W25Q80 ONLY) and compare my dump...08-24-2025, 03:08 AM

Hey there,
first time posting here. I have been lurking a bit trying to find a solution but with little to no avail.
So I have a Lenovo ThinkPad P15 Gen2. When I got it (for free) it was turning on but not charging because the battery was unplugged. When I plug the battery in, the Laptop won't boot at all.
Specs:- Type: Lenovo ThinkPad P15 Gen2 20YQ-001KGE
- CPU, GPU, RAM work fine (not involved in the Problem)
So the first thought was to toss the battery and get a new one, as clearly the BMS is throwing errors or something.
Now I noticed...
