MoBo repair looking for IC

So I have bought a used M73 Tiny with Intel 4130 for an audio setup.

Got it two weeks and lost the front and left back USB ports.... 

In the BIOS or Linux they are not working. 

The power is okay got 5V from all ports. 


Opened up the pc and did some measuring. The USB 3.0 blue port and left back the Data - and Data + are connected to ground when i measure.


So I want to change the IC's but the number on the IC is nowhere to be found.

Attached a picture of the IC 119 13xxUJG.


Can some Lenovo Technician or Lenovo enthousiast point me in an IC?


Also saw the current MoBo 03T7344 is not available anymore? Substituted for another type??

There are no circuit diagrams available

Re: MoBo repair looking for IC

OK thanks  


So in search of a new MoBo. 


I have found the 03t7252 originally for M93. But with all usb3.0 ports so a nice upgrade 


But i see it's for Win7. Would that give problems on win10? 


Why the board is related on a OS Version?
