Lenovo ThinkPad P1 Gen2 18809-1 Boardview
-
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... -

Good day, everyone,
My ThinkPad E15 Gen2 suddenly stopped charging the battery and when the battery died the laptop is bricked.
The cause seems to be the power delivery circuit, namely the firmware on 24256e (UB9 on the schematic) chip.
I could not find the updated dump (current version is 2FF9 as per Lenovo) for this chip anywhere. So, please, if anyone has it or can make a dump from a working machine, please, share.
