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.
s/n: PF33180Q
Thank you....

Lenovo Thinkpad L15 (CPU 10th Gen) Supervisor Password
Hello All,
I recently acquired a new Lenovo Thinkpad L15 Gen 1 with a i3 10110U.
- MB: GL4A0/GL5A0 NM-C631
But the issue is, after opening and dismantling it to clean it / changing the thermal paste, I realized that there is a Supervisor Password.
As this serie is quite new, I don't know is there is a solution to remove it
?
I can give you every information I have in my possession if needed specially the Bios Dump.
Thanking you 1 million times in advance
