M58 LPT Question

I have over 400 junk M58's (7373-A34) that were ordered without a parallel port.  Somebody in procurement can't read.  Anyways, I see that there is a 25 pin connector on the Panda L-IQ45 mainboard.  How do I enable the port to allow parallel printers to be used with these PC's?  I assume it is possible since the plug is on the mainboard.

 

Any assistance is greatly appreciated.

Re: M58 LPT Question

The M58 requires a parallel port cable to be installed.  Order part number 43N9022 for the cable. You can see a diagram of the motherboard and a description of this part in the  Hardware Maintenance Manual on the Lenovo support website.  http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-70910

Re: M58 LPT Question

Thank you for the response.  After spending time on the telephone with Lenovo and them telling me it was not possible to resolve this issue, I finally found a solution that (mostly) worked.  I purchased a 25 pin cable w/adapter bracket and installed it.  After much headache, I finally figured out that the printer must be connected and powered on to configure the port correctly in the BIOS.  This works as long as the printer remains connected to the port.  If the LPT cable ever becomes disconnected, the settings disappear.  I will deal with that I guess.

 

Who would think that computers would be shipped without a parallel port installed but available on the mainboard.  I would hope that a BIOS update will become available in the very near future to turn this port on permanently so I do not have to keep resetting the parallel port in the future...just a thought Lenovo (if you are reading any of this)

Re: M58 LPT Question

Finally I found the solution for second COM2 port and LPT port.

For activation is necessary to connect at each port, a 1K resistor between GND and Port Enable pin.

Only after doing this you can enter in BIOS and to be able to see the COM and LPT port, just enable them in BIOS menu, and make the settings.

For COM2 connect a resistor (1K) between pin 9 and 10.

Main board-Connector as seen from above:
   -----------------------------
    |    |09|07|05|03|01|
    -----------------------------
    |12|10|08|06|04|02|
    -----------------------------
   Pin-Nr. Signal
    01      DSD/DCD
    02      DSR
    03      RxD
    04      RTS
    05      TxD
    06      CTS
    07      DTR
    08      RI
    09      GND
    10      COM2-Enable
    12      not connected
   COM2-Enable: PIN10-->1kOhm-->GND enables COM2

 

For LPT connect a resistor between pin 25 and another GND pin from 18 to 24. (You have to modify your bracket to connect the wire from pin 25 to another one between 18-24 GND, and in his place put a resistor 1K to GND, also to one of GND pins 18-24).

This is the real numbering on the main board, is in the right.

The table I used haves a different numbering (In the left side), but the designations of each pin is correct.

Re: M58 LPT Question

I bought in 2015 a refurbished

"Lenovo ThinkCentre 58p" ( DuoCore 2x 3 Ghz, 4 GB RAM, 160 GB HDD, DVD-ROM, Win7Pro->Win10Pro now running by free upgrade ).

 

I sourced the missing parallel port with proper cable, from an old 486-ISA Multi-IO card ( 2x serial, parallel, game )...

It was just necessary to activate the parallel printer port in the Lenovo BIOS.

The red cable within the flat ribbon cable is at the "L" of the on-board printed "LPT1".

No hardware modification ( i.e. no 1K resistor ect. ) was necessary.

 

For PCL5 drivers for old laser graphics printer with Win10, see
