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... -

Hello,
I'm searching for a usb firmware for the notebook of the title.
The issue is that it stays at 5V only input from both usb c ports and the controller TPS65994 has been replaced.
The firmware should be the U5502 and I upload the dump of it.
Lenovo provides firmware updates but I was unable to find the appropriate file inside.

Thank you.... -
