ThinkCentre M700 Small: how to enable the parallel port?

2021-03-30, 1:48 AM

I have a ThinkCentre M700 SFF type 10GS and my customer needs a hardware (non-USB) parallel port. I purchased and installed a parallel port header that attaches to the motherboard LPT header. The problem I'm having is that there is no option in the BIOS to enable/configure a parallel port and Windows 10 (x64) does not detect a parallel port. The latest BIOS version (M05KT90A) is installed and this is a clean Windows installation with all Lenovo drivers installed (via Lenovo System Update).

 

How can I allow Windows to detect the parallel port? Thanks to anyone who has any ideas. :-)

Hello samhathaway!


Welcome to community forums


According to psref, parallel port is optional and you can refer here: https://psref.lenovo.com/Product/ThinkCentre_M700_SFF

So I suggest you share the machine type model(ex: 10GS000YUS) so it could help gather more details about this machines' variant?


Let us know.

Thanks for your response. The machine type model is 10GSS0LX00, but I don't see that model listed on the PSREF page you linked. Thanks again!

Checking on parts lookup shows FRU 45J9598 or 43N9022 would be compatible but 3rd party cable may have an issue and is not guaranteed so it can be a challenge finding a compatible one. 

 

You can refer to this link: https://pcsupport.lenovo.com/ph/en/products/desktops-and-all-in-ones/thinkcentre-m-series-desktops/thinkcentre-m700-tower-and-small/10gs/10gss0lx00/parts/display/compatible

 

You can buy the part here(US & CA): https://lenovo.encompass.com/

Regards

Thank you for the link. One additional question: Since the parallel cable (FRU 45J9598) is a passive component, I would expect the parallel port (LPT1) to show up in the Windows device manager and the parallel port settings to be present in the BIOS regardless of whether the parallel cable is installed. Is that right? Or is there something about the cable that tells the computer to enumerate the device? (Other computers I have worked with that have internal LPT headers show the device in the BIOS and in Windows regardless of whether a parallel cable is attached.) Thanks for your insight.
