T-520 Missing Driver PCI Serial Port

2015-11-24, 0:26 AM

Thinkpad T-520. New Install of Windows 10 Pro 64 bit. Device Manager says no driver for the PCI Serial Port. What driver am I looking for? TIA for any help and/or ideas.

Are you able to ge the Hardware Ids for the PCI Serial Port? This way we can figure out what exactly it is :)

 

If you right click the device in Device Manager, click Properties, go to the Details tab and select Hardware Ids from the dropdown box you should be able to copy and paste them into a post here.

I just installed Windows 10 on an old T520 and device manager shows the same PCI device missing drivers:

 

PCI\VEN_8086&DEV_1C3D&SUBSYS_21CF17AA&REV_04
PCI\VEN_8086&DEV_1C3D&SUBSYS_21CF17AA
PCI\VEN_8086&DEV_1C3D&CC_070002
PCI\VEN_8086&DEV_1C3D&CC_0700

 

I found this page: https://support.lenovo.com/ca/en/downloads/ds037583

but the T520 isn't in the list of supported systems. Has anyone figured out how to resolve this?

 

For the record the system seems to be running fine in its current state.

I had the same problem. You will need to download the latest Serial Over LAN (SOL) driver for you computer. Go to device manager, select the pci serial port, manually update the driver, point it to search in (c)drive --> DRIVERS --> WINDOWS --> AMT. That should download the SOL driver.

Hope this helps!
