Lenovo ThinkPad Edge E550: Not working USB on thinkpad e550

Fri, 24 Apr 2026 02:09:04 -0700

Hi. I have a Thinkpad E550 and USB port on the right side (next to DC in) is not working. I checked with USB load that it provides 5V, 1A. I tried Lenovo diagnostics in BIOS and it doesn't detect USB mass storage device. I disassembled the computer and checked for cold solder joints on the USB, they were OK (verified with multimeter). The USB port in question is on a small daughter board. Thinkpad e550 parts, part number: 00HT632

I replaced the flat flex cable and it didn't help. I'm wondering if I should replace the daughter board. Since it's expensive, before I order one I would like to ask if somebody has access to schematic of that daughter board and can verify if there's some circuitry on the board that can cause the USB data communication to fail.

On this machine is installed linux mint. Here is "lsusb -v" output

Thanks a lot!
